Accounting Policies [Abstract]
BASIS OF PRESENTATION	NOTE A — BASIS OF PRESENTATION The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U. S. generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U. S. generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three-month period ended March 31 2017, are not necessarily indicative of the results that may be expected for the year ending December 31, 2017 or any other period. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s annual report on Form 10-K for the year ended December 31, 2016. Use of Estimates The preparation of these condensed consolidated financial statements required the use of certain estimates by management in determining the Company’s assets, liabilities, revenues and expenses. Actual results could differ from those estimates. Specific areas, among others, requiring the application of management’s estimates include determination of the allowance for loan losses, the valuation of investment securities available for sale, fair value of impaired loans, contingent liabilities, fair value of other real estate owned, and the valuation of deferred tax assets. Actual results could differ from those estimates.

RECENTLY ISSUED ACCOUNTING STAN

RECENTLY ISSUED ACCOUNTING STANDARDS, Not adopted as of March 31, 2017	3 Months Ended

Accounting Changes and Error Corrections [Abstract]
RECENTLY ISSUED ACCOUNTING STANDARDS	NOTE B — RECENTLY ISSUED ACCOUNTING STANDARDS, Not adopted as of March 31, 2017 The following provides a brief description of accounting standards that have been issued but are not yet adopted that could have a material effect on the Company's financial statements: In March 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-08, requiring entities to amortize premiums on certain purchased callable debt securities to their earliest call date. The accounting for purchased callable debt securities held at a discount did not change. Amortizing the premium to the earliest call date generally aligns interest income recognition with the economics of instruments. This guidance requires a modified retrospective transition under which a cumulative adjustment will be made to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. This guidance is effective for fiscal years beginning after December 15, 2018. Adoption is being evaluated as to its effect on the Company’s operating results or financial condition. In January 2017, the FASB issued ASU 2017-04, eliminating Step 2 from the goodwill impairment test. Under the amendments to the guidance, an entity should perform its goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. The loss recognized, however, should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. The guidance is effective for annual periods or any interim goodwill impairment tests beginning after December 15, 2019 using a prospective transition method. Early adoption is permitted. Adoption of this standard is being evaluated as to its effect on the Company’s operating results or financial condition. In August and November 2016, the FASB issued final guidance via ASU 2016-15 and ASU 2016-18, which address classification of certain cash receipts and cash payments, including changes in restricted cash, in the statement of cash flows. The guidance may change how an entity classifies certain cash receipts and cash payments on its statement of cash flows, the purpose being to reduce diversity in practice. The Company is evaluating the impact of ASU 2016-15 and 2016-18 on the Company’s statement of cash flows which will generally be applied retrospectively for fiscal years beginning after December 15, 2017. In June 2016, the FASB issued ASU 2016-13 for “Measurement of Credit Losses on Financial Instruments” to replace the incurred loss impairment methodology with a current expected credit loss methodology for financial instruments measured at amortized cost and other commitments to extend credit. Expected credit losses reflect losses over the remaining contractual life of an asset, considering the effect of voluntary prepayments and considering available information about the collectability of cash flows, including information about past events, current conditions, and supportable forecasts. The resultant allowance for credit losses reflects the portion of the amortized cost basis that the entity does not expect to collect. Additional quantitative and qualitative disclosures are required upon adoption. The Company is assessing current loan loss estimation models and processes to determine the need for changes as part of its evaluation of the impact of this new accounting guidance. Adoption is required January 1, 2020, with early adoption permitted on January 1, 2019. In March 2016, under ASU 2016-04, “Liabilities – Extinguishments of Liabilities, Breakage for Certain Prepaid Stored-Value Products” the FASB intends for entities to recognize liabilities for the sale of prepaid stored value products redeemable for goods, services, or cash. This guidance aligns recognition of breakage for these liabilities in a way consistent with how gift card breakage will be recognized. The Company is currently evaluating the impact of adopting the new guidance on its consolidated financial statements. Effective date for implementation of the guidance is for annual periods after December 15, 2018. In February 2016, the FASB amended existing guidance related to the recognition of lease assets and lease liabilities on the balance sheet and disclosures of key information about leasing arrangements, under ASU 2016-02. The guidance requires all parties to classify leases to determine how to recognize lease-related revenue and expense. The amendment requires lessees to put most leases on their balance sheet and record expenses to the income statement. Changes in the guidance eliminate real estate centric provisions for sale-leaseback transactions, including initial direct costs and lease execution costs for all entities. For lessors, the new FASB standard modifies classification criteria and accounting for sales type and direct financing leases. The Company is currently evaluating the impact of adopting the new guidance on its consolidated financial statements. The amended accounting guidance is applicable to periods after December 15, 2018 and interim periods within that year. In January 2016, the FASB issued ASU 2016-01 for “Recognition and Measurement of Financial Assets and Liabilities.” The ASU addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The update requires: a) equity investments (except those accounted for under the equity method of accounting) to be measured at fair value and recognized in net income, b) simplifies impairment assessments of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, and if impaired requires measurement of the investment at fair value, c) eliminates the requirement to disclose the methods and significant assumptions used to estimate the fair value, d) requires entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, e) requires an entity to present separately in other comprehensive income the portion of the total change in fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments, f) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements, and g) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. The ASU is effective for fiscal years beginning after December 15, 2017, and must be adopted on a modified retrospective basis, including interim periods within those fiscal years. The adoption of ASU 2016-01 is being evaluated for its impact on the Company’s operating results and financial condition. In May 2014, the FASB issued ASU 2014-09, “Revenue Recognition – Revenue from Contracts with Customers.” The ASU is a converged standard between the FASB and the IASB that provides a single comprehensive revenue recognition model for all contracts with customers across transactions and industries. The primary objective of the ASU is revenue recognition that represents the transfer of control of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Revenue associated with loans and securities is not in the scope of the new guidance, and the Company’s evaluation and implementation effort for contracts within the scope of the standard is ongoing. The Company plans to adopt the new guidance on January 1, 2018.

Under the Company’s risk rating system, the Company classifies problem and potential problem loans as “Special Mention,” “Substandard,” and “Doubtful” and these loans are monitored on an ongoing basis. Substandard loans include those characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Loans classified as Substandard may require a specific allowance. Loans classified as Doubtful have all the weaknesses inherent in those classified Substandard with the added characteristic that the weaknesses present make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. The principal on loans classified as Doubtful is generally charged off. Loans that do not currently expose the Company to sufficient risk to warrant classification in one of the aforementioned categories, but possess weaknesses that deserve management’s close attention are deemed to be Special Mention. Risk ratings are updated any time the situation warrants. Loans not meeting the criteria above are considered to be pass-rated loans and risk grades are recalculated at least annually by the loan relationship manager.

Impaired Loans and Allowance for Loan Losses	NOTE F — IMPAIRED LOANS AND ALLOWANCE FOR LOAN LOSSES The Company’s Troubled Debt Restructuring (“TDR”) concessions granted generally do not include forgiveness of principal balances. Loan modifications are not reported in calendar years after modification if the loans were modified at an interest rate equal to the yields of new loan originations with comparable risk and the loans are performing based on the terms of the restructuring agreements. Most loans prior to modification were classified as an impaired loan and the allowance for loan losses is determined in accordance with Company policy.

A defaulted TDR is generally placed on nonaccrual and specific allowance for loan loss is assigned in accordance with the Company’s policy.

(2) Recurring fair value basis determined using observable market data. (3) See Note F. Nonrecurring fair value adjustments to loans identified as impaired reflect full or partial write-downs that are based on the loan’s observable market price or current appraised value of the collateral in accordance with ASC 310. (4) Fair value is measured on a nonrecurring basis in accordance with ASC 360 . The fair value of impaired real estate loans which are collateral dependent is based on recent real estate appraisals less estimated costs of sale. For residential real estate impaired loans, appraised values or internal evaluation are based on the comparative sales approach. These impaired loans are considered level 2 in the fair value hierarchy. For commercial and commercial real estate impaired loans, evaluations may use either a single valuation approach or a combination of approaches, such as comparative sales, cost and/or income approach. A significant unobservable input in the income approach is the estimated capitalization rate for a given piece of collateral. At March 31, 2017, the range of capitalization rates utilized to determine fair value of the underlying collateral averaged approximately 7.8 8.4 1.7 4.1 0.4 Fair value of available for sale securities are determined using valuation techniques for individual investments as described in Note D. When appraisals are used to determine fair value and the appraisals are based on a market approach, the fair value of other real estate owned (“OREO”) is classified as a level 2 input. When the fair value of OREO is based on appraisals which require significant adjustments to market-based valuation inputs or apply an income approach based on unobservable cash flows, the fair value of OREO is classified as Level 3. Transfers between levels of the fair value hierarchy are recognized on the actual date of the event or circumstances that caused the transfer, which generally coincides with the Company’s monthly and/or quarter-end valuation process. During the three months ended March 31, 2017, there were no transfers between level 1 and level 2 assets carried at fair value. For loans classified as level 3 the transfers in totaled $ 0.1 0.3 Charge-offs recognized upon loan foreclosures are generally offset by general or specific allocations of the allowance for loan losses and generally do not, and did not during the reported periods, significantly impact the Company’s provision for loan losses. For OREO classified as level 3 during the first three months of 2017, there were no foreclosed loans transferred in and no migrated branches taken out of service added.

The short maturity of Seacoast’s assets and liabilities results in having a significant number of financial instruments whose fair value equals or closely approximates carrying value. Such financial instruments are reported in the following balance sheet captions: cash and due from banks, interest bearing deposits with other banks, federal funds purchased, securities sold under agreement to repurchase, maturing within 30 days, and FHLB borrowings. The following methods and assumptions were used to estimate the fair value of each class of financial instrument for which it is practicable to estimate that value at March 31, 2017 and December 31, 2016: Securities The Company reviews the prices supplied by independent pricing services, as well as their underlying pricing methodologies, for reasonableness and to ensure such prices are aligned with traditional pricing matrices. The fair value of collateralized loan obligations is determined from broker quotes. From time to time, the Company will validate, on a sample basis, prices supplied by the independent pricing service by comparison to prices obtained from other brokers and third-party sources or derived using internal models.

Business Combinations [Abstract]
Business Combinations	NOTE L — BUSINESS COMBINATIONS Acquisition of Floridian Financial Group, Inc. On March 11, 2016, the Company completed its acquisition of Floridian Financial Group, Inc. (“Floridian”), the parent company of Floridian Bank. Simultaneously, upon completion of the merger, Floridian’s wholly owned subsidiary bank, Floridian Bank, was merged with and into Seacoast Bank. Floridian, headquartered in Lake Mary, Florida, operated 10 branches in Orlando and Daytona Beach, of which several were consolidated with Seacoast locations. This acquisition added approximately $ 417 337 267 100 Under the terms of the definitive agreement, Floridian shareholders received, at their election, (i) the combination of $4.29 in cash and 0.5291 shares of Seacoast common stock, (ii) $12.25 in cash, or (iii) 0.8140 shares of Seacoast common stock, subject to a customary proration mechanism so that the aggregate consideration mix equaled 35% cash and 65% Seacoast shares (based on Seacoast’s closing price of $15.47 per share on March 11, 2016). The following table represents the purchase price paid to Floridian shareholders in connection with the acquisition: March 11, 2016 Shares exchanged for cash $ 26,699,000 Number of Floridian Financial Group, Inc. common shares outstanding 6,222,119 Per share exchange ratio 0.5289 Number of shares of common stock issued 3,291,066 Multiplied by common stock price per share on March 11, 2016 $ 15.47 Value of common stock issued 50,912,791 Total purchase price $ 77,611,791 Business Combinations Measurement Initial Report Period As Adjusted Date of acquisition March 11, 2016 Adjustments March 11, 2016 (in thousands) Assets: Cash $ 28,243 $ 0 $ 28,243 Investment securities 66,912 95 67,007 Loans, net 268,249 (2,112) 266,137 Fixed assets 7,801 (628) 7,173 Core deposit intangibles 3,375 0 3,375 Goodwill 29,985 1,647 31,632 Other assets 12,879 998 13,877 $ 417,444 $ 0 $ 417,444 Liabilities: Deposits $ 337,341 $ 0 $ 337,341 Other liabilities 2,492 0 2,492 $ 339,833 $ 0 $ 339,833 March 11, 2016 (In thousands) Book Balance Fair Value Loans: Single family residential real estate $ 38,304 $ 37,367 Commercial real estate 172,531 167,105 Construction/development/land 20,546 18,108 Commercial loans 39,070 37,804 Consumer and other loans 3,385 3,110 Purchased credit-impaired 6,186 2,643 Total acquired loans $ 280,022 $ 266,137 For the loans acquired we first segregated all acquired loans with specifically identified credit deficiency factor(s). The factors we considered to identify loans as Purchased Credit Impaired (“PCI”) loans were all acquired loans that were nonaccrual, 60 days or more past due, designated as Troubled Debt Restructured (“TDR”), graded “special mention” or “substandard.” These loans were then evaluated to determine estimated fair values as of the acquisition date. As required by generally accepted accounting principles, we are accounting for these loans pursuant to ASC Topic 310-30. The table below summarizes the total contractually required principal and interest cash payments, management’s estimate of expected total cash payments and fair value of the loans as of March 11, 2016 for purchased credit impaired loans. (In thousands) March 11, 2016 Contractually required principal and interest $ 8,031 Non-accretable difference (4,820) Cash flows expected to be collected 3,211 Accretable yield (568) Total purchased credit-impaired loan acquired $ 2,643 Loans without specifically identified credit deficiency factors are referred to as Purchased Unimpaired Loans (“PULs”) for disclosure purposes. These loans were then evaluated to determine estimated fair values as of the acquisition date. Although no specific credit deficiencies were identifiable, we believe there is an element of risk as to whether all contractual cash flows will be eventually received. Factors that were considered included the economic environment both nationally and locally as well as the real estate market particularly in Florida. We have applied ASC Topic 310-20 accounting treatment to the PULs. The Company believes the deposits assumed from the acquisition have an intangible value. The Company applied ASC Topic 805, which prescribes the accounting for goodwill and other intangible assets such as core deposit intangibles, in a business combination. In determining the valuation amount, deposits were analyzed based on factors such as type of deposit, deposit retention, interest rates and age of deposit relationships. The Company recognized goodwill of $ 32 Operating results of the Company for the three months ended March 31, 2017 include the operation of the acquired assets and assumed liabilities since the date of acquisition of March 11, 2016.

In determining the valuation amount, a third party analyzed the deposits based on factors such as type of deposit, deposit retention, interest rates and age of deposit relationships. The Company recognized intangibles (including goodwill) of approximately $ 13 15 Acquisition of GulfShore Bancshares, Inc. On April 7, 2017, the Company completed its acquisition of GulfShore Bancshares, Inc. (“GulfShore”), the parent company of GulfShore Bank. Simultaneously, upon completion of the merger, GulfShore’s wholly owned subsidiary bank, GulfShore Bank, was merged with and into Seacoast Bank. GulfShore, headquartered in Tampa, Florida, operated 3 branches in Tampa and St. Petersburg, of which all have been retained as Seacoast locations. This acquisition added approximately $ 321 285 258 100 Under the terms of the definitive agreement, GulfShore shareholders received the combination of $1.47 in cash and 0.4807 shares of Seacoast common stock (based on Seacoast’s closing price of $23.94 per share on April 7, 2017). April 7, 2017 Shares exchanged for cash $ 8,033,999 Number of GulfShore Bancshares, Inc. common shares outstanding 5,464,308 Per share exchange ratio 0.4807 Number of shares of common stock issued (approximately) 2,626,693 Multiplied by common stock price per share on April 7, 2017 $ 23.94 Value of common stock issued 62,883,030 Total purchase price $ 70,917,029 The acquisition will be accounted for under the acquisition method of accounting in accordance with ASC Topic 805, Business Combinations. Some disclosures are being omitted at this time as the information is not available and incomplete. The Company will recognize goodwill on this acquisition which is nondeductible for tax purposes as this acquisition is a nontaxable transaction. The goodwill will be calculated based on the fair values of the assets acquired and liabilities assumed as of the acquisition date, which at the time of this filing were incomplete and reliant upon use of third party experts for pending valuations, including the core deposit intangible and pending appraisals on purchased unimpaired loans and purchased credit impaired loans, bank premises and other fixed assets, other real estate owned, subordinated debt, and remaining assets and other liabilities. Loans that are nonaccrual and all loan relationships identified as impaired as of the acquisition date will be considered by management to be credit impaired and will be accounted for pursuant to ASC Topic 310-30. The Company believes the deposits assumed from the acquisition will have an intangible value. The Company will be applying ASC Topic 805, which prescribes the accounting for goodwill and other intangible assets such as core deposit intangibles, in a business combination. In determining the valuation amount, deposits will be analyzed based on factors such as type of deposit, deposit retention, interest rates and age of deposit relationships. Acquisition of Palm Beach Community Bank On May 4, 2017, the Company announced that it had entered into an agreement and plan of merger with Palm Beach Community Bank, a Florida Bank (“PBCB”). The agreement provides that PBCB will merge with and into Seacoast Bank. PBCB operates four branches in West Palm Beach, Florida with deposits of approximately $ 281 290
