Accounting Policies [Abstract]
Basis of Presentation	The consolidated financial statements include the accounts of Winnebago Industries, Inc. and its wholly-owned subsidiaries. Intercompany account balances and transactions have been eliminated in consolidation. The use of the terms "Winnebago Industries," "Winnebago," "we," "our," and "us" in this Quarterly Report on Form 10-Q, unless the context otherwise requires, refers to Winnebago Industries, Inc. and its wholly owned subsidiaries. The interim unaudited consolidated financial statements included herein are prepared pursuant to the rules and regulations of the United States (“U.S.”) Securities and Exchange Commission (“SEC”). The information furnished in these consolidated financial statements includes normal recurring adjustments, unless noted otherwise in the Notes to Consolidated Financial Statements, and reflects all adjustments that are, in management’s opinion, necessary for a fair presentation of such financial statements. The consolidated financial statements are prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”). GAAP requires us to make estimates and assumptions that affect amounts reported. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to SEC rules and regulations. The consolidated financial statements included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended August 31, 2024 filed with the SEC. Interim results of operations are not necessarily indicative of the results to be expected for the full fiscal year ending August 30, 2025.
Segment Update	In conjunction with the Grand Design RV entrance into the motorized RV category, we established a Grand Design motorhomes operating segment in the first quarter of Fiscal 2025. This newly created operating segment is included in the Motorhome RV reportable segment. Prior period amounts have not been reclassified as the impact was not significant.
Comprehensive Income	Comprehensive income represents the change in stockholders’ equity from transactions and other events and circumstances from sources other than shareholders.
Subsequent Events	In preparing the accompanying unaudited consolidated financial statements, we have evaluated subsequent events for potential recognition and disclosure through the date of this filing, noting no material subsequent events.
Recently Issued Accounting Pronouncements	In November 2024, the Financial Accounting Standards Board (“FASB”) issued ASU 2024-04, which clarifies the assessment of whether certain settlements of convertible debt instruments should be accounted for as an inducement conversion or extinguishment of convertible debt. The new guidance is effective for annual reporting periods beginning after December 15, 2025, and interim periods within those annual periods. We are currently evaluating the impact of the standard on our consolidated financial statements and related disclosures. In November 2024, the FASB issued ASU 2024-03, which requires disclosure of additional disaggregated information about significant expenses within relevant income statement captions, such as purchases of inventory, employee compensation, depreciation, amortization and depletion. The new guidance is effective for annual reporting periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. We are currently evaluating the impact of the standard on our consolidated financial statements and related disclosures. We will adopt the standard in our Annual Report on Form 10-K for our fiscal year ending August 26, 2028 and filings thereafter. In March 2024, the SEC adopted a final rule under SEC Release No. 33-11275, The Enhancement and Standardization of Climate-Related Disclosures for Investors. The new rule will require disclosure of greenhouse gas emissions, including Scope 1 and Scope 2 emissions; climate-related risks, governance, and oversight; and the financial impacts of severe weather events and other natural conditions, subject to certain materiality thresholds. These disclosures are required to be phased in to our annual reporting beginning in Fiscal 2026. However, in April 2024, the SEC stayed the implementation of this rule pending the outcome of legal challenges. We continue to monitor developments and evaluate the impact of adoption on our Consolidated Financial Statements and related disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires expanded disclosures primarily related to the effective tax rate reconciliation and income taxes paid. The new guidance is effective for annual reporting periods beginning after December 15, 2024, with early adoption permitted. We are currently evaluating the impact of the standard on our consolidated financial statements and related disclosures. We will adopt the standard in our Annual Report on Form 10-K for our fiscal year ending August 29, 2026 and annual filings thereafter. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires incremental disclosures about significant segment expenses regularly provided to the Chief Operating Decision Maker. The new guidance is effective for annual reporting periods beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. We are currently evaluating the impact of the standard on our consolidated financial statements and related disclosures. We will adopt the standard in our Annual Report on Form 10-K for our fiscal year ending August 30, 2025 and filings thereafter.
Fair Value Measurements	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. These securities, used to fund the Executive Deferred Compensation Plan, are classified as Level 1 as they are traded in an active market for which closing stock prices are readily available. Refer to Note 11 in the Notes to Consolidated Financial Statements included in Item 8 of Part II of our Annual Report on Form 10-K for the fiscal year ended August 31, 2024 for additional information regarding these plans. The proportion of the assets that will fund the deferred compensation payments within a year are included in prepaid expenses and other current assets on the Consolidated Balance Sheets. The remaining assets are classified as non-current and are included in other long-term assets on the Consolidated Balance Sheets. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis Certain non-financial assets are measured at fair value on a nonrecurring basis. These assets primarily include goodwill, intangible assets, property, plant and equipment, and right-of-use lease assets. These assets were originally recognized at amounts equal to the fair value determined at date of acquisition or purchase. If certain triggering events occur, or if an annual impairment test is required, we will evaluate the non-financial asset for impairment. If an impairment has occurred, the asset will be written down to its current estimated fair value. No impairments were recorded for non-financial assets in the six months ended March 1, 2025 or February 24, 2024. Assets and Liabilities Not Measured at Fair Value Certain financial instruments are not measured at fair value but are recorded at carrying amounts approximating fair value based on their short-term nature. These financial instruments include cash and cash equivalents, receivables, accounts payable, and other payables. If these instruments were measured at fair value in the financial statements, they would be classified as Level 1 in the fair value hierarchy. Our debt obligations are recorded at amortized cost but measured at fair value for disclosure purposes. The fair value of our debt was determined using current quoted prices in active markets for our publicly traded debt obligations, which is classified as Level 1 in the fair value hierarchy. See Note 8 in the Notes to Consolidated Financial Statements included in Item 1 of Part I of this Quarterly Report on Form 10-Q for the fair value of our debt.
Repurchase Commitments	Generally, manufacturers in the same industries as us enter into repurchase agreements with lending institutions which have provided wholesale floorplan financing to dealers. Most dealers 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 units purchased. Our repurchase agreements generally 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 24 months, provide that our liability will be the lesser of remaining principal owed by the dealer to the lending institution, or dealer invoice less periodic reductions based on the time since the date of the original invoice. Our liability cannot exceed 100% of the dealer invoice. In certain instances, we also repurchase inventory from 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 recreational vehicles or boats to repurchase current inventory if a dealership exits the business. The total contingent liability on all repurchase agreements was approximately $1,750.1 million and $1,673.7 million at March 1, 2025 and August 31, 2024, respectively. Our loss reserve for repurchase commitments contains uncertainties because the calculation requires management to make assumptions and apply judgment regarding a number of factors. Our risk of loss related to these 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-end reporting date subject to a repurchase agreement, net of the greater of periodic reductions per the agreement or dealer principal payments. Based on these repurchase agreements and our historical loss experience, an associated loss reserve is established, which is included in other current liabilities on the Consolidated Balance Sheets. Our repurchase accrual was $1.1 million and $1.1 million at March 1, 2025 and August 31, 2024, respectively. Repurchase risk is affected by the credit worthiness of our dealer network. We do not believe there is a reasonable likelihood that there will be a material change in the estimates or assumptions used to establish the loss reserve for repurchase commitments.
Revenue	We do not have material contract assets or liabilities. Allowances for uncollectible receivables are established based on historical collection trends, write-off history, consideration of current conditions and expectations for future economic conditions.
