Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Basis of Presentation
	The "Company," "we," "our" and "us" are used interchangeably to refer to Winnebago Industries, Inc. and its wholly-owned subsidiary, Winnebago of Indiana, LLC, as appropriate in the context.
	We were incorporated under the laws of the state of Iowa on February 12, 1958 and adopted our present name on February 28, 1961. Our executive offices are located at 605 West Crystal Lake Road in Forest City, Iowa. Our telephone number is (641) 585-3535; our website is www.winnebagoind.com. Our common stock trades on the NYSE under the symbol “WGO.”
	In our opinion, the accompanying unaudited consolidated financial statements contain all adjustments, consisting of normal recurring accruals, necessary to present fairly our consolidated financial position as of February 28, 2015 and the consolidated results of income and comprehensive income and consolidated cash flows for the first six months of Fiscal 2015 and 2014. The consolidated statement of income and comprehensive income for the first six months of Fiscal 2015 is not necessarily indicative of the results to be expected for the full year. The consolidated balance sheet data as of August 30, 2014 was derived from audited financial statements, but does not include all of the information and footnotes required by GAAP for complete financial statements. These interim financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto appearing in our Annual Report on Form 10-K for the fiscal year ended August 30, 2014.
	Fiscal Period
	We follow a 52-/53-week fiscal year, ending the last Saturday in August. Both Fiscal 2015 and Fiscal 2014 are 52-week years.
	New Accounting Pronouncements
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which specifies how and when to recognize revenue as well as providing informative, relevant disclosures. ASU 2014-09 will become effective for fiscal years beginning after December 15, 2016 (our Fiscal 2018). We are currently evaluating the impact on our consolidated financial statements.
	In August 2014, the FASB issued ASU 2014-15, Going Concern (Subtopic 205-40), which provides guidance on management's responsibility in evaluating whether there is substantial doubt about a company's ability to continue as a going concern and related footnote disclosures. ASU 2014-15 will become effective for years ending after December 15, 2016 (our Fiscal 2017). We are currently evaluating the impact of ASU 2014-15 on our consolidated financial statements.

Risks and Uncertainties [Abstract]
Concentration Risk	Concentration Risk
	One of our dealer organizations accounted for 20.1% and 20.7% of our consolidated net revenues for the first six months of Fiscal 2015 and Fiscal 2014, respectively. A second dealer organization accounted for 19.2% and 12.6% of our consolidated net revenues for the first six months of Fiscal 2015 and Fiscal 2014, respectively. The loss of either or both of these dealer organizations could have a significant adverse effect on our business. In addition, deterioration in the liquidity or creditworthiness of these dealers could negatively impact our sales and could trigger repurchase obligations under our repurchase agreements.

Fair Value Disclosures [Abstract]
Investments and Fair Value Measurements	Investments and Fair Value Measurements
	Assets and Liabilities that are Measured at Fair Value on a Recurring Basis
	We account for fair value measurements in accordance with ASC 820, Fair Value Measurements and Disclosures, which defines fair value, establishes a framework for measurement and expands disclosure about fair value measurement. The fair value hierarchy requires the use of observable market data when available. In instances in which the inputs used to measure fair value fall into different levels of the fair value hierarchy, the fair value measurement has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. Our assessment of the significance of a particular item to the fair value measurement in its entirety requires judgment, including the consideration of inputs specific to the asset or liability.
	Cash Equivalents
	The carrying value of cash equivalents approximates fair value as original maturities are less than three months. Our cash equivalents are comprised of money market funds traded in an active market with no restrictions.
	The following tables set forth by level within the fair value hierarchy our financial assets that were accounted for at fair value on a recurring basis at February 28, 2015 and August 30, 2014 according to the valuation techniques we used to determine their fair values:
				Fair Value Measurements
				Using Inputs Considered As
	(In thousands)	Fair Value at		Level 1 Quoted Prices in Active Markets for Identical Assets		Level 2 Significant Other		Level 3 Significant

	The following table provides a reconciliation between the beginning and ending balances of items measured at fair value on a recurring basis in the table above that used significant unobservable inputs (Level 3):
		Three Months Ended				Six Months Ended

	Sales	—		—		—		(2,350		)
	Balance at end of period	$	—	$	—	$	—	$	—
	The following methods and assumptions were used to estimate the fair value of each class of financial instrument:
	Assets that Fund Deferred Compensation
	Our assets that fund deferred compensation are marketable equity securities measured at fair value using quoted market prices and primarily consist of equity-based mutual funds. They are classified as Level 1 as they are traded in an active market for which closing stock prices are readily available. These securities fund the Executive Share Option Plan (see Note 9), a deferred compensation program, and are presented as other assets in the accompanying balance sheets.
	Assets and Liabilities that are Measured at Fair Value on a Nonrecurring Basis
	Our non-financial assets, which include goodwill and property, plant and equipment, are not required to be measured at fair value on a recurring basis. However, if certain triggering events occur, or if an annual impairment test is required, we must evaluate the non-financial asset for impairment. If an impairment did occur, the asset is required to be recorded at the estimated fair value. During the first six months of Fiscal 2015, no impairments were recorded for non-financial assets.

	During the third quarter of Fiscal 2014 we delivered 520 RV rental units to Apollo, a US RV rental company. Under the terms of a sales agreement with Apollo, all units were paid for upon delivery. To secure an order of this magnitude, we contractually agreed to repurchase up to 343 of the units at specified prices after one season of rental use (by no later than December 31, 2014) provided certain conditions are met. On December 29, 2014 the repurchase timing was extended from December 31, 2014 to February 28, 2015. The original cost of these units was depreciated down to the estimated net realizable value of the rental units during the time frame that the units were in rental use. During the first quarter of Fiscal 2015, we were released of repurchase obligation for 124 units as Apollo sold the units in the market place. As units subject to repurchase were sold, we removed the remaining net investment in operating lease as well as the operating lease repurchase obligation. In the second quarter of Fiscal 2015, we were released of the remaining repurchase obligations and as a result, there were no associated assets or liabilities on the balance sheet at February 28, 2015.
	Net lease revenue was recorded ratably over the rental period that Apollo held the units based upon the difference between the proceeds received and the estimated repurchase obligation less the estimated depreciation expense of the unit. We were not required to repurchase any units from Apollo, thus we did not record a gain or loss for the difference between the estimated residual value of the unit and the actual resale value as a component of net lease revenue. We recorded net lease revenue of $626,000 during Fiscal 2014, $623,000 and $1.3 million during the second quarter and first six months of Fiscal 2015, respectively.
	In March 2015, we received a rental order of similar size from Apollo for the 2015 rental season. Under the terms of the 2015 sales agreement, the sales of these units will all be normal sales with no units recorded as operating leases. Based on the planned delivery schedule, we will ship approximately two-thirds of these units in the third quarter of Fiscal 2015 and one-third in the fourth quarter of Fiscal 2015.

	On October 31, 2012, we entered into the Credit Agreement with GECC. The Credit Agreement provides for an initial $35.0 million revolving credit facility based on eligible inventory and was to expire on October 31, 2015, unless terminated earlier in accordance with its terms. There is no termination fee associated with the Credit Agreement.
	The Credit Agreement contains no financial covenant restrictions for borrowings where we have excess borrowing availability under the facility of greater than $5.0 million. The Credit Agreement requires us to comply with a fixed charge ratio if excess borrowing availability under the facility is less than $5.0 million. In addition the Credit Agreement also includes a framework to expand the size of the facility up to $50.0 million, based on mutually agreeable terms at the time of the expansion. The initial unused line fee associated with the Credit Agreement is 0.5% per annum and has the ability to be lowered based upon facility usage.
	The Credit Agreement contains typical affirmative representations and covenants for a credit agreement of this size and nature. Additionally, the Credit Agreement contains negative covenants limiting our ability, among other things, to incur debt, grant liens, make acquisitions, make certain investments, pay certain dividends and distributions, engage in mergers, consolidations or acquisitions and sell certain assets. Obligations under the Credit Agreement are secured by a security interest in all of our accounts and other receivables, chattel paper, documents, deposit accounts, instruments, equipment, inventory, investment property, leasehold interest, cash and cash equivalents, letter-of-credit rights, most real property and fixtures and certain other business assets.
	On May 28, 2014, we amended this Credit Agreement (the "Amended Credit Agreement"). The Amended Credit Agreement extends the term of the credit facility from October 31, 2015 to May 28, 2019.  In addition, interest on loans made under the Amended Credit Facility will be based on LIBOR plus a margin of 2.0%.  The amendment also revised and added definitions of several terms including an expanded Restricted Payment Basket that now permits up to $15.0 million purchases of company stock and cash dividends to be excluded from the Fixed Charge ratio annually.  In addition, the definition of Eligible Accounts was expanded to permit certain receivables to be included in the Borrowing Base.  The Amended Credit Agreement also permits us to engage in certain sale lease buyback transactions in the ordinary course of business subject to certain restrictions and increases our ability to incur capital lease obligations.
	During the second quarter we utilized the credit facility from time to time to meet working capital needs, however at the end of the period no borrowings were outstanding. As of the date of this report, we are in compliance with all material terms of the Amended Credit Agreement, and no borrowings are outstanding.

	We provide our motorhome customers a comprehensive 12-month/15,000-mile warranty on our Class A, B and C motorhomes, and a 3-year/36,000-mile structural warranty on Class A and C sidewalls and floors. We provide a comprehensive 12-month warranty on all towable products. We have also incurred costs for certain warranty-type expenses which occurred after the normal warranty period. We have voluntarily agreed to pay such costs to help protect the reputation of our products and the goodwill of our customers. Estimated costs related to product warranty are accrued at the time of sale and are based upon past warranty claims and unit sales history and adjusted as required to reflect actual costs incurred, as information becomes available. A significant increase in dealership labor rates, the cost of parts or the frequency of claims could have a material adverse impact on our operating results for the period or periods in which such claims or additional costs materialize.
	Changes in our product warranty liability are as follows:

	Postretirement Health Care Benefits
	We provide certain health care and other benefits for retired employees hired before April 1, 2001, who have fulfilled eligibility requirements at age 55 with 15 years of continuous service. We use a September 1 measurement date for this plan and our postretirement health care plan currently is not funded.
	We established dollar caps on the amount that we will pay for postretirement health care benefits per retiree on an annual basis to reduce our exposure to medical inflation. Retirees are required to pay a monthly premium in excess of the employer dollar caps for medical coverage based on years of service and age at retirement.

Stockholders' Equity	Stockholders' Equity
	Stock-Based Compensation
	We have a 2014 Omnibus Equity, Performance Award, and Incentive Compensation Plan (as amended, the "Plan") approved by shareholders in place which allows us to grant or issue non-qualified stock options, incentive stock options, share awards and other equity compensation to key employees and to non-employee directors.
	On October 15, 2014 and October 16, 2013 the Human Resources Committee of the Board of Directors granted an aggregate of 99,600 and 84,200 shares, respectively, of restricted common stock to our key employees and non-employee directors under the Plan. The value of the restricted stock award is determined using the intrinsic value method which, in this case, is based on the number of shares granted and the closing price of our common stock on the date of grant.
	Stock-based compensation expense was $447,000 and $436,000 during the second quarters of Fiscal 2015 and 2014, respectively. Stock-based compensation expense was $1.3 million and $1.4 million during the six months of Fiscal 2015 and 2014, respectively. Of the $1.3 million expense recognized in Fiscal 2015, $838,000 related to the October 15, 2014 grant of 99,600 shares. The remainder is related to the amortization of previously granted restricted stock awards, as well as non-employee director stock units issued in lieu of director fees. Compensation expense is recognized over the requisite service period of the award or over a period ending with the employee's eligible retirement date, if earlier.
	Dividends
	On December 17, 2014, the Board of Directors declared a quarterly cash dividend of $0.09 per share of common stock, which was paid on February 4, 2015 to shareholders of record at the close of business on January 21, 2015.
	On March 18, 2015, the Board of Directors declared a quarterly cash dividend of $0.09 per share of common stock, payable on May 6, 2015 to shareholders of record at the close of business on April 22, 2015.

Commitments and Contingencies Disclosure [Abstract]
Contingent Liabilities and Commitments	Contingent Liabilities and Commitments
	Repurchase Commitments
	Generally, manufacturers in the RV industry enter into repurchase agreements with lending institutions which have provided wholesale floorplan financing to dealers. Most dealers' RVs are financed on a "floorplan" basis under which a bank or finance company lends the dealer all, or substantially all, of the purchase price, collateralized by a security interest in the recreation vehicles purchased.
	Our repurchase agreements provide that, in the event of default by the dealer on the agreement to pay the lending institution, we will repurchase the financed merchandise. The terms of these agreements, which generally can last up to 18 months, provide that our liability will be the lesser of remaining principal owed by the dealer or dealer invoice less periodic reductions based on the time since the date of the original invoice. Our contingent liability on these repurchase agreements was approximately $429.6 million and $363.8 million at February 28, 2015 and August 30, 2014, respectively.
	In certain instances, we also repurchase inventory from our dealers due to state law or regulatory requirements that govern voluntary or involuntary relationship terminations. Although laws vary from state to state, some states have laws in place that require manufacturers of recreation vehicles to repurchase current inventory if a dealership exits the business. Incremental repurchase exposure beyond existing repurchase agreements, related to dealer inventory in states that we have had historical experience of repurchasing inventory, totaled $6.5 million and $6.8 million at February 28, 2015 and August 30, 2014, respectively.
	Our risk of loss related to our repurchase commitments is significantly reduced by the potential resale value of any products that are subject to repurchase and is spread over numerous dealers and lenders. The aggregate contingent liability related to our repurchase agreements represents all financed dealer inventory at the period reporting date subject to a repurchase agreement, net of the greater of periodic reductions per the agreement or dealer principal payments. Based on the repurchase exposure as previously described, we established an associated loss reserve. Our accrued losses on repurchases were $1.5 million as of February 28, 2015 and $2.2 million as of August 30, 2014.
	A summary of repurchase activity is as follows:
		Three Months Ended				Six Months Ended
	(Dollars in thousands)	February 28,		March 1,		February 28,		March 1,
		2015		2014		2015		2014
	Inventory repurchased:
	Units	—		—		54		14
	Dollars	$	—	$	—	$	7,156	$	325
	Inventory resold:
	Units	53		—		55		14
	Cash collected	$	6,102	$	—	$	6,140	$	257
	Loss realized	$	1,022	$	—	$	1,033	$	68
	Units in ending inventory	—		—		—		—
	The majority of the units resold in the second quarter of Fiscal 2015 were attributable to a single dealership. The loss realized in the quarter had previously been reserved for, and the decrease in the loss reserve is the result of the resale of the repurchased units.
	We do not believe there is a reasonable likelihood that there will be a material change in the future estimates or assumptions we use to calculate our loss reserve for repurchase commitments. A hypothetical change of a 10% increase or decrease in our significant repurchase commitment assumptions at February 28, 2015 would have affected net income by approximately $293,000.
	Litigation
	We are involved in various legal proceedings which are ordinary litigation incidental to our business, some of which are covered in whole or in part by insurance. We believe while the final resolution of any such litigation may have an impact on our results for a particular reporting period, the ultimate disposition of such litigation will not have any material adverse effect on our financial position, results of operations or liquidity.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes
	We account for income taxes under ASC 740, Income Taxes. The objectives of accounting for income taxes are to recognize the amount of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in our financial statements or tax returns.
	We file tax returns in the US federal jurisdiction, as well as various international and state jurisdictions. Although certain years are no longer subject to examinations by the IRS and various state taxing authorities, net operating loss carryforwards generated in those years may still be adjusted upon examination by the IRS or state taxing authorities if they either have been or will be used in a future period. As of February 28, 2015, our federal returns from Fiscal 2011 to present continue to be subject to review by the IRS. With few exceptions, the state returns from Fiscal 2009 to present continue to be subject to review by the taxing jurisdictions. A number of years may elapse before an uncertain tax position is audited and finally resolved, and it is often very difficult to predict the outcome of such audits.
	As of February 28, 2015, our unrecognized tax benefits were $2.8 million including accrued interest and penalties of $1.1 million. If we were to prevail on all unrecognized tax benefits recorded, $1.9 million of the $2.8 million would benefit the overall effective tax rate. It is our policy to recognize interest and penalties accrued relative to unrecognized tax benefits as tax expense. It is reasonably possible that the amount of unrecognized tax benefits with respect to our other unrecognized tax positions will increase or decrease during the next twelve months; however, an estimate of the amount or range of the change cannot be made at this time.
