High-Wind Party Backup Plan

A high-wind backup plan gives a host a wind-speed threshold, a teardown order for tents and decor, and indoor swaps for outdoor games.

Build a wind backup plan

Your tent and balloon arch are set up for an outdoor party, and the forecast is showing sustained wind near 20 mph by the time guests arrive. That’s the number that matters, not the gust forecast, for deciding whether decor and games stay outside or move in.

What wind speed actually forces a change?

Use 20 mph sustained as your working line, and treat higher gusts as an earlier warning. Below that, most tents and games hold up fine. Above it, tall decor and canopies become hazards. A Party Planning Checklist for Real Life covers the broader day-of decisions this threshold fits into, and a rental company’s own bounce house contract usually names the exact wind speed that triggers deflation.

What comes down first when the wind picks up?

Tall or wide decor and tents come down before anything else, since they’re what actually cause injury or damage in a gust. Balloons and loose paper decor follow. Rainy Day Party Plan uses a similar teardown-first approach that transfers directly to a wind call.

What do you text guests about the wind call?

Keep it to one line: “Wind’s picking up, we’re moving the party indoors at [location], same time.” Send it once your before-setup check confirms wind is near your threshold, not after a gust has already taken the tent down. Guests with young kids appreciate the heads-up early enough to pack an extra layer if the indoor space runs cooler than the yard.

Which games and activities need a swap?

Bubbles, kite flying, and anything with loose paper stop working once wind picks up. High Energy Party Games has active alternatives that don’t depend on calm air, and Cold-Snap Party Backup Plan covers a different weather threshold if the forecast is also dropping temperature.

What if a guest gets hurt by wind-blown gear before you can react?

A tent pole or a heavy decoration catching a gust can cause a real injury, not just a mess. If it happens, What to Do When the Birthday Child Gets Sick covers the same triage-first, party-second thinking that applies to any injury: check the kid, decide if it needs more than a bandage, and only then worry about salvaging the setup. Treat a near-miss as your signal to move the wind threshold check up earlier next time, not as bad luck.

Questions About Moving a Party Indoors for High Wind

What wind speed actually means a party should move indoors?

Sustained wind above 20 mph is the general line where tents, balloon arches, and pop-up canopies stop being safe outdoors. Gusts higher than the sustained number make the call earlier.

What comes down first if wind picks up mid-party?

Tall or wide decor and tents come down first since they cause the most damage in a gust. Lightweight items like balloons and paper decor follow once the bigger pieces are secured.

What do I text guests if the party changes location for wind?

Keep it short: 'Wind's picking up, we're moving the party indoors at [location], same time.' Send it as soon as your before-setup check confirms the call.

Which outdoor games stop working in high wind?

Bubbles, kite flying, and anything using loose paper or lightweight balls become frustrating or unsafe. Swap in a relay, scavenger hunt, or tag-based game instead.

Is a bounce house safe in high wind?

No. Most bounce house rental agreements require deflation above 15-20 mph sustained wind. Check your rental contract's specific number and plan to deflate it before that point.
