How Do Camps Keep Kids (and Staff) Safe in a Heat Wave?
Running camp in a heat wave is one of the harder things you will do all summer.
Kids run low on energy. Staff get stretched. Small behaviour problems start to feel bigger. The day becomes twice as hard as it needs to be.
This guide covers eight practical things camps can do to protect staff and campers during hot weather without cancelling the fun. These approaches work for both overnight and day camps.
The short answer
Safe heat management at camp comes down to three things: change when you move, watch humidity not just temperature, and build cool-down time into the rhythm of the day. The sections below go deeper on each one.
Change when you move
Heat is as much about timing as temperature.
Schedule high-movement activities for the coolest parts of the day. Early morning and later afternoon work well for most camps, both overnight and day programs.
Move quieter activities into the hottest hours. Arts, reading, card games, board games, and indoor program time all hold up well in the midday heat.
Build flexibility into your daily schedule. Being able to swap a block quickly is more valuable than holding to the original plan when the temperature climbs.
When planning outdoor spaces, track where shade falls at different times of day. A sunny field at 1 pm can feel 10 to 15 degrees hotter than the shaded area right beside it.
What makes heat dangerous? Humidity and wind
The question camps need to ask is not only "how hot is it?" It is "can bodies actually cool down right now?"
High humidity makes sweat nearly useless. Without evaporation, the body struggles to regulate temperature. Low wind makes everything worse.
Create a simple heat-risk chart for your camp that accounts for three things: temperature, humidity, and wind. Attach clear responses to each zone.
A sample structure:
Green: normal programming
Yellow: shorten games, add water breaks
Orange: move to shade or indoors, stop high-intensity running activities
Red: no strenuous activity; water, shade, rest, and quiet program only
Train staff to check the chart before starting any activity, not midway through.
How long should camp activities run in the heat?
You do not have to cancel movement. You just have to change the dose.
On hot days, cut running games and sports sessions down. A 20-minutes-on, 10-minutes-off structure works well for most age groups. Use walking versions of games or skill-based challenges. Add structured cool-down breaks between active periods, in shade or indoors.
Teach staff that scaling back is professional. It is good risk management, not a sign of weakness.
How to cool campers down during the day
Cooling down is a rhythm, not a one-time fix.
Rotate groups through your coolest spaces during the hottest hours. For overnight camps, that might mean an air-conditioned building, a basement, or a heavily shaded grove. For day camps, consider whether a nearby splash pad, community pool, or indoor partner space could be part of your heat plan.
Set up cool-down stations with tubs of cool water for hands and forearms, spray bottles, and cold cloths.
Use water play with intention. Sprinklers, slip-and-slides, and water games all help, but combine them with shade and rest rather than treating water time as just another high-energy block.
A simple rule worth teaching every staff member: if you are hot enough to pour water over your head, you are also hot enough to sit in the shade for a few minutes.
What is a pre-cool window, and why does it matter?
Pre-cooling means bringing campers' body temperature down before a high-movement block rather than reacting after things feel rough.
Before any known hot period, bring your group into shade or a cooler indoor space for a few minutes. Offer cold drinks or ice slushies. Use cool, damp cloths on necks, arms, and faces. Remind staff of the shortened time limits and water break plan.
Think of it as building up a safety buffer before you need it.
How long does it take for campers to adjust to heat?
Bodies need time to adjust to hot weather, typically seven to fourteen days.
Treat the first stretch of hot days the way you would treat altitude. Gradually increase the length and intensity of outdoor activities. Make hydration, shade, and rest extra visible in your schedule and in how staff talk about the day. Avoid stacking multiple intense blocks back-to-back in the sun.
Let your staff know that both they and the campers will adapt. That only happens if you give everyone the space to do it.
What are the early warning signs of heat illness in kids?
The earlier you catch heat problems, the easier they are to manage.
Teach staff to watch for:
Dizziness or a fuzzy, unfocused feeling
Nausea or stomach cramps
Headache
Unusual fatigue or irritability
A racing or pounding heart
Give staff a clear, simple response: stop the activity, move to shade or a cool space, cool down with water and rest, and loop in a supervisor or your health team.
Stopping early is good leadership. Make sure your staff know that, and say it more than once.
How do you build a heat safety culture at camp?
A one-time training does not hold up through a three-week heat wave.
Weave heat thinking into the daily rhythm of your camp. Ask "What's our heat plan for today?" every morning. Make "Where do we go if someone starts to feel too warm?" a standard question in group meetings. Design programs with a shade option and a cool-down plan already built in.
The bigger picture is worth naming directly. Climate and physical activity are connected. As heat waves become more common, camps will need to change not just what they do but when, where, and how they do it.
That is how you keep your people moving, laughing, and safe all summer long.
Take good care,
