This article helps child care providers and directors keep children safe on hot, sunny days especially during warm-weather seasons in California. Young children can get sick from heat faster than adults, and heat illness can become serious quickly. California also has workplace heat rules for indoor and outdoor settings, and programs should stay alert.
How do I spot heat illness early in children and staff?
Heat illness can start small and turn serious fast. Teach staff to watch for changes in behavior not just temperature.
Common warning signs (act quickly):
-
Heavy sweating, tiredness, weakness
-
Headache, dizziness, nausea
-
Muscle cramps
-
Fast breathing
Danger signs (get emergency help right away):
-
Confusion, fainting, trouble waking up
-
Hot, red skin (may be dry)
-
Very high temperature or child “looks very sick”
What to do immediately if you see warning signs:
-
Move the child/staff member to shade or A/C
-
Offer cool water if they are awake and able to drink
-
Cool the body with wet cloths, a fan, or cool (not icy) water on skin
-
Call for medical help if symptoms are severe or not improving quickly
What daily routine helps prevent heat problems before they start?
The best prevention is a simple routine staff can follow every day.
Use this easy “Heat Safety Routine”:
-
Check weather + Heat Index before outdoor play
-
Plan short outdoor blocks (instead of one long block)
-
Offer water before, during, and after outdoor time
-
Schedule the most active play for cooler times (early morning)
-
Add extra rest breaks in shade
If you want a quick “stoplight” way to decide outdoor time (green/yellow/red conditions), ChildCareEd’s California weather guidance is a helpful starting point:

How do I set up shade that actually keeps kids cooler?
Shade works best when it is easy to reach and big enough for the whole group.
Good shade options (low-cost to bigger upgrades):
-
Use existing trees or building shade first
-
Add a pop-up canopy (check stability/wind safety)
-
Create shade with shade sails (installed correctly)
-
Use stroller covers or shade tents for infants (with airflow)
Shade checklist for outdoor time:
-
Shade is available before children go outside
-
Shade area has airflow (not trapped heat)
-
Staff can see children clearly (active supervision)
-
Children can move in/out of shade easily
California’s outdoor heat prevention rules emphasize access to shade and water for workers; while child care has additional licensing requirements, the same safety idea applies: shade access should be planned, not “optional.”
How often should children drink water in hot weather?
Children often don’t notice they are thirsty until they are already dehydrated. So your program should offer water on a schedule.
Simple water plan (works for most preschool groups):
-
Water available all day
-
Water offered:
-
At arrival
-
Before going outside
-
Every 10–15 minutes outdoors during hot weather
-
After coming inside
-
Before nap/rest and after nap/rest
-
Practical tips that make hydration easier:
-
Use labeled water bottles (or labeled cups)
-
Set a “water timer” for outdoor time
-
Use quick phrases: “Three sips, then play!”
-
Encourage staff to model drinking water too (#HealthyHabits)
When should we change outdoor schedules for heat and sun?
If it feels hot to adults, it is often too hot for long play for young children.
Schedule smarter:
-
Do active running games early in the day
-
Swap to calm outdoor play (bubbles, chalk, nature walk) later
-
Move big-motor play indoors if it’s too hot
Helpful idea: split outdoor time into two short blocks
-
15–20 minutes outdoors in the morning
-
10–15 minutes outdoors later (only if conditions are safe)

What are simple sun-safety steps that families and staff can follow?
Sun safety is not just sunscreen. It’s also clothing, timing, and shade.
Easy #sunsafety checklist:
-
Dress children in lightweight, light-colored clothes
-
Use wide-brim hats when possible
-
Choose shaded areas for story time and waiting lines
-
Try to avoid the strongest sun hours when possible
About sunscreen:
-
Follow your licensing rules and program policies
-
Use parent permissions if required
-
Apply sunscreen before going outside (it takes time to work)
-
Reapply as recommended on the label, especially with sweating/water play
How do we protect infants and toddlers during heat?
Infants and toddlers are at higher risk in heat because they can’t always tell you what they feel.
Extra steps for infants/toddlers:
-
Shorter outdoor time (and more shade time)
-
More frequent water breaks (as developmentally appropriate)
-
Watch diapers: fewer wet diapers can be a dehydration sign
-
Never use covered spaces that trap heat (strollers need airflow)
What should staff know about indoor heat safety in California?
Some classrooms get hot even when children are indoors—especially during heat waves. California has an indoor heat illness prevention standard (Title 8, section 3396) approved in June 2024, and it applies to many workplaces when indoor temperatures reach 82°F.
Even if your child care licensing rules are separate, it’s smart to plan for indoor heat days:
-
Use fans safely (not blowing directly on infants)
-
Keep cool water available
-
Reduce heavy movement activities indoors
-
Use cool-down breaks and lighter routines
What ChildCareEd training can help my team prevent heat illness and improve safety?
These courses support the exact routines that keep children safe during hot weather:
