Bounce house wind speed limits: what every manufacturer and regulator publishes
Checked October 2026
There is no single bounce house wind limit. Seven of the ten companies we read say 15 mph, Magic Jump and Bouncer Depot say 20, and JumpOrange says units are rated 15 to 25. CPSC says never operate above 25 mph, gusts included. Maryland's current rule bars operating at 15 mph sustained, or at 25 mph gusts lasting 3 seconds. ASTM F2374, as quoted in a 2022 journal paper, defaults to 15 mph sustained when the maker gives no figure. Use the lowest number that applies.
Ask what wind speed is too much for a bounce house and the published answer is 15, 20 or 25 mph, depending on who wrote it. Each of those numbers is on a page you can open, and the tables below quote them side by side.

What manufacturers and sellers publish
| Company and page | What it says | Limit |
|---|---|---|
| EZ Inflatables owner's manual (an undated copy, reference 010918, hosted by Interactive Playgrounds) | "Do Not Operate when winds exceed 15MPH" | 15 mph |
| MoonwalkUSA owner's manual | "DO NOT operate inflatable in winds above 15 mph," and stakes and weights are "not intended to anchor inflatable during high winds" | 15 mph |
| Eagle Bounce operating procedures and its manual page | The PDF repeats the MoonwalkUSA wording; the page says limits are "typically 15-20 MPH" | 15 mph, or 15 to 20 |
| Blast Zone commercial FAQ | "We do not recommend using any inflatables in winds over 15 MPH," although some protocols "require engineering to 25 MPH" | 15 mph |
| Happy Jump safety guidelines (September 2024) | "If wind speeds exceed 15 mph, do not inflate or use the bounce house." | 15 mph |
| BounceWave setup guide (June 2025) | "Deflate the inflatable if wind exceeds 15 mph or during rain." | 15 mph |
| Sky High Party Rentals help page (a rental company) | Winds "should not exceed 15mph," with "extreme caution should be used at any speed above 10mph" | 15 mph, caution at 10 |
| JumpOrange wind post and anchoring guide | The post says most bounce houses are rated for a maximum of 15 to 25 mph; the guide calls 15 mph the shutdown threshold | 15 to 25, then 15 |
| Magic Jump news page (2011) and Magic Jump Rentals safety rules | in a 2011 TV interview Magic Jump's Bagumyan says that at 20 miles an hour a unit should be shut down however well tied, and that this warning is in every Magic Jump owner's manual; the rental arm says no use when "winds exceed 20mph" | 20 mph |
| Bouncer Depot FAQ | "Deflate and store your bounce house when wind exceeds 20 mph." | 20 mph |
Seven of the ten put the line at 15. Magic Jump and Bouncer Depot put it at 20. JumpOrange gives a range and then picks 15 in another post. Nobody in this set tells you to work at 25.
These are company pages, not the plate on your unit. EZ, Eagle Bounce and MoonwalkUSA are owner's manuals, and the rest are blog posts, FAQs or help pages from sellers and rental companies. The Magic Jump quote is fifteen years old. The number that governs your unit is on its information plate and in its manual.
What regulators, insurers and venues publish
| Source | What it says | Number |
|---|---|---|
| CPSC safety bulletin, commercial section | "Various manufacturers recommend maximum wind speeds from 15 to 25 mph, depending on the ride"; above 25 mph, gusts included, "it is dangerous to operate any inflatable ride" | Maker's limit, never above 25 |
| Same bulletin, residential section | "Do not use the product if wind speeds exceed 20 mph." | 20 mph |

| Maryland, COMAR 09.12.66 (current text) | An inflatable "shall not be operated when the maximum sustained wind speed is 15 mph or greater," or with gusts lasting 3 seconds or longer at 25 mph or greater; users are evacuated in those conditions | 15 sustained, 25 gusts |

Maryland is the one state we found with hard numbers. The Library of Maryland Regulations lists chapter 66 as revised by emergency provision effective March 4, 2026 and adopted effective May 11, 2026, and that text sets 15 mph sustained and 25 mph for 3-second gusts. The older PDF of chapter 66 still posted on the Department of Labor's site says 25 mph flat, so a cap of 25 you find there is out of date. The Department's amusement page points to the amendments and a March 26, 2026 outreach session.
Where the sources split
CPSC says three different things
The bulletin's consumer section says stop at 20 mph. Its commercial section defers to the maker, with 25 as the ceiling. A 2019 press release for consumers says 15 to 25. A 2022 paper in the American Meteorological Society's Bulletin reads the CPSC bulletin as a 20 mph rule, which is the consumer line. If you rent to families, you are in the commercial section, but your customers will find the consumer line first.
ASTM gives three numbers
The paper's authors read F2374 as setting design strength at 25 mph, an operating limit 5 mph under whatever the anchors were designed for (so 20 if they were designed for 25), and a 15 mph default when the maker states nothing. They add that the standard blurs sustained wind and gusts. JumpOrange's anchoring guide describes the same default and warns that the 25 mph design figure is not an operating limit. F2374 itself is a paid document. Everything here is as the cited sources quote it, so ask your manufacturer which edition the unit was built to.
Whether a wind number voids your policy
JumpOrange's insurance guide says most policies have "strict 15-20 mph wind speed limits above which coverage is void." That is an unverified claim from a manufacturer's marketing page, with no policy form behind it. None of the insurer pages we read says it. Kelly asks for a written wind policy, First Commercial says documented anchor procedures and wind-rating awareness cut premium and claims, and Pro Insurance Group says wind monitoring protocols improve pricing. None states a numeric exclusion. Ask your carrier to point to the weather condition in the policy form itself. A manufacturer's blog can't speak for your policy.
Incident counts
XINSURANCE's inflatable page says wind-related incidents caused "approximately 209 deaths and three injuries" in the United States. The journal paper counts 132 wind incidents worldwide from 2000 to 2021, with at least 479 injuries and 28 deaths. The two cannot both be right, and only the paper lists its incidents.
Incidents under the limits
The same journal paper checked 85 incidents with wind data. In 22 percent the wind was between 0 and 15 mph, in 33 percent between 0 and 20, and in 51 percent between 0 and 25. It cites a wind-engineering study that put the speed needed to move an inflated, anchored, occupied unit at about 22.4 mph. Dust devils and thunderstorm gusts do not wait for the forecast.
Writing your rule
- Take the lowest number among the unit's plate, its manual, the venue's rules and the state's. A 20 mph manual under a 15 mph venue rule means 15.
- Say whether the number is sustained or gusts, and put the gust figure in too.
- Name who makes the call and the order of steps: evacuate, power off, open the zips, deflate, secure the vinyl.
- Train the person who will be there. CPSC's bulletin includes a wind-estimation table: at 13 to 18 mph, evacuate any unit not designed above 15, and at 19 to 24, any unit not designed for 25. It also tells rental companies to give renters a short training on estimating wind speed.
- Buy an anemometer. The paper reports that F2374 expects attendants to be trained to assess wind with one, or with the Beaufort scale.
The rental agreement is where the rule becomes a promise to the customer: clause 4 of the rental agreement guide has an example line. Anchoring and the rest of what the standard asks of operators are on the safety and ASTM F2374 page. Insurers treat the written rule as a condition of getting quoted, as the coverage page explains. Tall wet units are covered in the water slide guide. The permit guide has the city and fire office pages, including James City County's checklist that defers to the label, and the requirements page has the state-by-state rules.
