Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation Unless the context otherwise requires, the use of the terms "Winnebago Industries," "Winnebago", and "the Company" in these Notes to Condensed Consolidated Financial Statements refers to Winnebago Industries, Inc. and its wholly-owned subsidiaries. In the opinion of management, the accompanying Condensed Consolidated Financial Statements contain all adjustments necessary for a fair presentation as prescribed by accounting principles generally accepted in the United States (“GAAP”). All adjustments were comprised of normal recurring adjustments, except as noted in these Notes to Condensed Consolidated Financial Statements. Interim results are not necessarily indicative of the results to be expected for the full year. The interim Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the fiscal year ended August 29, 2020.
Fiscal Period	Fiscal Period The Company follows a 52-/53-week fiscal year, ending the last Saturday in August. Fiscal 2021 and Fiscal 2020 are both a 52-week year.
Cash and cash equivalents	Cash and cash equivalents Cash equivalents include all investments with original maturities of three months or less or which are readily convertible into known amounts of cash and are not legally restricted. Accounts at each banking institution are insured by the Federal Deposit Insurance Corporation up to $250,000, while the remaining balances are uninsured.
Subsequent Events	Subsequent Events In preparing the accompanying unaudited Condensed Consolidated Financial Statements, the Company evaluated subsequent events for potential recognition and disclosure through the date of this filing. There were no material subsequent events, except for the item noted below.
Recently Adopted/Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncements The Company adopted Accounting Standards Codification ("ASC") Topic 326, Financial Instruments—Credit Losses (“Topic 326”), effective August 30, 2020. The new impairment model (known as the current expected credit loss ("CECL") model) is based on expected losses rather than incurred losses. Topic 326 is applicable to financial assets measured at amortized cost, such as accounts receivable and deposits. It requires historical loss data to be adjusted to reflect changes in asset-specific considerations, current conditions and reasonable and supportable forecasts of future economic conditions. The expected credit losses are adjusted each period for changes in expected lifetime credit losses. The Company adopted Topic 326 using the modified retrospective transition approach, which involves recognizing the cumulative effect of initial adoption of Topic 326 as an adjustment to its opening retained earnings as of August 30, 2020. Therefore, comparative information prior to the adoption date has not been adjusted. As a result of adoption of Topic 326, the Company did not recognize an incremental allowance for credit losses on its accounts receivable for the first six months ended February 27, 2021. The adoption of this standard did not materially impact the Company's Condensed Consolidated Financial Statements. Recently Issued Accounting Pronouncements In August 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40). ASU 2020-06 reduces the number of models used to account for convertible instruments, amends diluted EPS calculations for convertible instruments, and amends the requirements for a contract (or embedded derivative) that is potentially settled in an entity's own shares to be classified in equity. The amendments add certain disclosure requirements to increase transparency and decision-usefulness about a convertible instrument's terms and features. Under the amendment, the Company must use the if-converted method for including convertible instruments in diluted EPS as opposed to the treasury stock method. ASU 2020-06 is effective for annual reporting periods beginning after December 15, 2021 (the Company's Fiscal 2023). Early adoption is allowed under the standard with either a modified retrospective or full retrospective method. The Company expects to adopt the new guidance in the first quarter of Fiscal 2023. While it will change the Company's diluted EPS reporting, the extent to which the standard will have a material impact on the Company's consolidated financial statements is uncertain at this time. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of Effects of Reference Rate Reform on Financial Reporting. ASU 2020-04 provides practical expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The expedients and exceptions provided by the amendments in this update apply only to contracts, hedging relationships, and other transactions that reference the London interbank offered rate (“LIBOR”) or another reference rate expected to be discontinued as a result of reference rate reform. These amendments are not applicable to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022. ASU 2020-04 is effective as of March 12, 2020 through December 31, 2022 and may be applied to contract modifications and hedging relationships from the beginning of an interim period that includes or is subsequent to March 12, 2020. The Company will adopt this standard when LIBOR is discontinued, and does not expect a material impact to its consolidated financial statements. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. ASU 2019-12 simplifies the accounting for income taxes by removing certain exceptions to the general principles of Topic 740. The standard is effective for annual reporting periods beginning after December 15, 2020 (the Company's Fiscal 2022), including interim periods within those annual reporting periods. The Company expects to adopt the new guidance in the first quarter of Fiscal 2022, and does not expect a material impact to its consolidated financial statements.
