How to Weatherproof Your School Carnival (aka What to Do If It Rains)
You can plan the cutest booths, order the best raffle baskets, and schedule the face painter down to the minute… but if the weather turns? All bets are off.
Whether it’s rain, wind, blazing heat, or even a surprise cold snap, the forecast can derail even the most beautifully planned school carnival—unless you’ve got a solid backup plan. And no, panicking and stuffing everything into the multipurpose room 20 minutes before opening does not count as a plan.
The good news? You don’t have to cancel or start from scratch. With a little prep and flexibility, you can create a weatherproof carnival that still raises money, delights families, and keeps everything running—rain or shine.
Let’s break it down step by step so you’re ready for whatever the clouds throw at you.
✅ 1. Start With a Backup Plan—Before You Even Need One
The key to weatherproofing your carnival is to think about rain before it’s on the forecast. Ideally, you’ll build your Plan B right into your planning process.
When choosing your date and layout, ask yourself:
- If it rains, where will everything go?
- Do you have access to the gym, cafeteria, or hallways as a backup?
- Are there covered areas like pavilions or breezeways for certain booths?
- Could your layout support a hybrid setup with indoor games and outdoor food trucks (or vice versa)?
Having these answers ready ahead of time means you won’t be scrambling for solutions the week of the event.
📝 Planning Tip: Add a “Weather Backup Plan” section to your main event checklist or binder. Even if you never need it, having it written out will save you from making a dozen last-minute decisions if the clouds roll in.
✅ 2: Watch the Forecast Like a Pro
The minute your event hits the calendar, the weather becomes your part-time obsession—and that’s totally normal. But before you start panic-texting the PTA group chat because the forecast shows a thunderstorm 10 days out… take a breath.
Here’s the reality:
- 7–10 days out: The forecast will change every 12 hours. Don’t panic yet—just start watching.
- 5 days out: If rain or storms are still on the radar, it’s time to review your Plan B and begin prepping a possible indoor layout.
- 2–3 days out: Have a conversation with school staff and vendors about your options and when you’ll make the final call.
- 24 hours before: This is your decision deadline. At this point, you’ll want to lock in your rain plan and start communicating the change to families and volunteers if needed.
What to look for besides rain:
- Wind – Anything over 15–20mph could make bounce houses, tents, or signage unsafe.
- Extreme heat – Temps over 85–90°F? You’ll need shade, water, and cooling breaks.
- Cold snaps – Surprise chill? Indoor activities and hot drinks will save the day.
☀️ Bonus Tip: Use a reliable weather app (AccuWeather, Weather Underground, or your local meteorologist’s updates) and don’t rely on a single phone app emoji.
✅ 3: Know What Can Be Moved (and What Can’t)
When the weather forces your hand, you don’t need to cancel the whole carnival—you just need to know what stays, what moves, and what needs a creative plan B. Some booths are indoor-friendly with minimal effort, while others need a little rethinking (or a rain check altogether).
Easy to Move Indoors:
These activities are low-mess, compact, and portable—perfect for gymnasiums, cafeterias, or even wide hallways.
- Raffle basket table
- Bake sale or snack stand
- Prize table
- Face painting & glitter tattoos
- Temporary tattoo stations
- Craft booths
- Carnival games like ring toss, duck pond, bean bag toss, or Plinko
💡 Tip: Use folding tables and labeled bins so you can move these stations quickly if the weather shifts at the last minute.
Needs a Backup Plan:
Some booths just don’t translate indoors without a little creativity—or they may need to be replaced entirely.
- Bounce houses (check with your vendor—some can move indoors!)
- Dunk tanks
- Petting zoos or pony rides
- Large inflatables or obstacle courses
- Games that involve water (squirt guns, sponge toss, etc.)
- Anything requiring grass or large open space
🎯 Rainy Day Swaps:
- Swap the dunk tank for a “Sponge Toss” at a target
- Replace water balloon toss with a ring toss or dry game
- Turn outdoor relays into indoor table-top challenges
🛑 Important: If you’re using electricity outdoors, make sure all cords, plugs, and power sources are rated for wet conditions—or move that booth inside.
✅ 4: Communicate Changes Clearly
So you’ve made the call to move things indoors—now it’s time to tell everyone (before they show up wandering around the muddy field wondering where the popcorn stand went).
Clear, fast, and repeated communication is key to keeping families and volunteers in the loop. Here’s how to do it right:
- Email blast to all school families (include map or list of new locations if possible)
- Post on social media—school, PTA, and class Facebook groups, Instagram, etc.
- Update your event website or sign-up link if you have one
- Send a text alert or push notification if your school uses an app like Remind or ClassTag
- Print updated maps or signs for event entrances and key locations (like check-in and bathrooms)
🗺️ Helpful Tip: If you’re handing out programs or printing signs, include a big “RAIN PLAN IN EFFECT” banner at the top so families know to follow the indoor version.
Keep Volunteers in the Loop too:
Your booth helpers need extra guidance when plans change.
Send them a quick message with:
- Their new location
- A reminder of their time slot
- Any important booth changes (e.g. “You’re now at Table 3 in the gym instead of outside the library.”)
👋 Optional but awesome: Assign a couple of “info helpers” to float at the entrance and help direct families or answer questions.
✅ 5. Make It Fun Anyway!
Just because you had to pivot indoors doesn’t mean your carnival has to feel like a rainy day backup plan. With the right attitude (and a few clever touches), you can keep the energy high, the kids happy, and the fundraising going strong.
Easy Ways to Boost the Indoor Vibe:
- Add music! Play a fun playlist in the gym or cafeteria to keep the energy up.
- Create a festive entry point. Use balloons, signs, or chalk art at the door to make the space feel inviting.
- Hand out “I braved the rain!” stickers or bonus tickets to keep the mood light.
Keep Volunteers Cheerful:
Rainy events can wear on your team, too. A few quick ways to keep spirits up:
- Offer snacks and bottled water at the volunteer check-in
- Hand out thank-you treats at the end of each shift
- Assign floaters to check in and relieve stressed booth workers
🎟️ Bonus Idea: Run a flash raffle or door prize giveaway just for volunteers who braved the weather.
🌦️ Big Picture Reminder: Kids don’t care if the duck pond is in the gym instead of on the blacktop. If the games are running and the prizes are flowing, they’re going to have a blast—and their parents will thank you for keeping things organized, fun, and dry.
☀️ 6. What If It’s Not Rain… But Wind, Heat, or Cold?
Carnival weather can be unpredictable in every season—so it pays to be ready for more than just rain. Whether you’re facing gusty winds, a surprise heatwave, or an unexpected chill, here’s how to keep things safe, comfortable, and fun.
🌬️ Wind
Strong winds can turn tents into kites and signage into frisbees—no thank you!
Wind-Proofing Tips:
- Secure all tents and pop-up canopies with sandbags, water weights, or heavy-duty stakes
- Avoid using balloons, lightweight decorations, or easels that can blow over
- Reinforce outdoor signage with zip ties or duct tape
- Double-check bounce house policies—many vendors won’t operate them in winds over 15–20 mph
✅ Plan B: Move signage and lightweight booths indoors or to sheltered areas like breezeways or courtyards.
☀️ Heat
If your carnival lands on a scorcher, you’ll need a plan to keep everyone safe and hydrated.
Hot Weather Tips:
- Set up shade tents or canopies over high-traffic areas like ticket sales and food booths
- Offer free water stations or sell cold drinks
- Provide cooling towels or misting spray fans for volunteers
- Limit bounce house time to short intervals and rotate kids out frequently
✅ Bonus Tip: Create a “Cool Down Corner” with chairs, fans, and ice water—great for overheated toddlers and volunteers.
❄️ Cold or Unexpected Chill
Planning a spring or fall event? Don’t rule out a last-minute temperature drop.
Cold Weather Tips:
- Move booths indoors if possible
- Serve hot drinks (think: cider, cocoa, or coffee at the bake sale!)
- Encourage volunteers to dress in layers and bring gloves
- Keep activities active—movement helps everyone warm up!
✅ Mood Booster: Hand out carnival-themed hand warmers or warm “thank you” drinks to your helpers.
A Little Rain (or Wind, or Sun) Doesn’t Have to Ruin the Fun
At the end of the day, the goal of your school carnival is to bring the community together, raise some funds, and give the kids a day they’ll talk about until next year. And with a little planning, a flexible mindset, and a weatherproof backup plan, you can absolutely still pull that off—even if the skies don’t cooperate.
So go ahead—print your Plan B, stock the cooler with water bottles, grab the duct tape, and remind your volunteers that you’ve got it covered (literally). Rain or shine, you’ve got this.
