Comfortable days • Better nights
Stay cooler at camp, from setup to bedtime.
Long summer days are great for camping—until your tent feels like an oven. A little planning can make a big difference: choose shade, keep air moving, bring enough safe drinking water, and save strenuous activities for cooler hours.
Start with the forecast, not the gear list. If dangerous heat is expected and you cannot reach a reliably cooler place, change the destination or postpone the trip.
1. Choose your destination with the heat in mind
Check daytime highs, overnight lows, humidity, heat alerts, and the campground’s current conditions. Confirm that drinking-water taps are working and ask about shade, fire restrictions, and nearby places to cool down.
Higher elevations can offer cooler conditions, but do not assume “mountain camping” means mild weather. Pack for the actual overnight forecast and local storm conditions. Ask park staff whether your planned activities are appropriate for the expected heat. National Park Service: planning for heat.
2. Look for shade without overlooking hazards
Choose an established site with shade during the hottest part of the day. Morning shade can also help keep direct sunlight off your tent while you sleep. Check how the sun will move rather than judging the site only when you arrive.
Look up before pitching: avoid dead trees, damaged limbs, and hanging branches. A branch’s size does not make it safe. Stay out of flood channels and follow campground rules about distance from water. NPS: choosing and setting up a campsite.
A lake or river nearby does not guarantee a cooler or safer site. Use designated swimming areas and follow local water-safety advice rather than depending on a quick dip as your heat plan.
3. Shade the tent and preserve airflow
A properly secured canopy or tarp can create extra shade where permitted. Leave an air gap above the tent and keep its vents clear. Follow the shelter’s setup instructions and secure it for expected wind.
Open the tent’s designed vents and use screened openings for airflow. Removing the rainfly may help in dry, settled conditions, but it also removes weather protection and may expose the interior to direct sun. Keep it available and reassess the forecast before bed.
A tent is not a cooling shelter. If it remains uncomfortably hot, spend time somewhere cooler rather than staying inside. A fan or shade tarp cannot make dangerous heat safe.
4. Use a fan for comfort, not as your backup plan
A securely placed battery-powered fan can improve air movement. Keep it and any cords clear of sleeping areas and water. In extreme heat, seek a cooler location; CDC advises against relying on fans alone when it is very hot. CDC: heat and your health.
5. Match bedding to the overnight forecast
For warm nights, a lightweight blanket or liner may be more comfortable than a zipped winter sleeping bag. Keep warmer bedding available if temperatures could drop, especially at elevation.
Do not leave essential insulation at home simply because the trip is in summer. Choose bedding you can adjust, and use the tent’s ventilation to balance comfort with weather protection.
6. Dress for sun, sweat, and changing conditions
Choose loose, lightweight clothing, a sun hat, sunglasses, and sunscreen. Breathability depends on fabric weight and construction—not just whether the label says cotton or synthetic. Quick-drying outdoor clothing can be useful when you are active.
Keep a dry layer available for the evening. Schedule hikes and camp chores for cooler hours, and plan shaded rest during the hottest part of the day. Shorten or cancel activities when conditions call for it.
7. Make a drinking-water plan before leaving
Bring safe drinking water for the group, your planned activities, cooking, and an unexpected delay. Confirm refill locations and carry a reserve rather than counting on a seasonal stream or an unverified campground tap.
Keep water accessible and drink regularly in the heat. Food and appropriate electrolyte replacement can matter during prolonged heavy sweating; do not rely on water alone while skipping meals, or force excessive amounts. Follow any clinician-prescribed fluid restrictions. NPS: hydration and heat precautions.
Do not assume clear stream water is safe
For untreated natural water, CDC recommends boiling to kill germs; another option is filtering followed by disinfection. Follow the full instructions for the method and equipment you use. These approaches do not make chemically contaminated water safe. CDC: water treatment while camping.
If you bring a Berkey® system to a developed campsite, follow the installed elements’ source-water requirements and care instructions. Do not assume a household gravity filter replaces a complete backcountry water-treatment plan.
8. Keep drinks cool—and perishable food cold
Insulated bottles, frozen water bottles, and ice packs can keep drinks pleasant and reduce trips to the cooler. Keep the cooler shaded and open it only when needed.
No-cook meals mean less time beside a hot stove, but sandwiches, salads, and cooked chicken may still need refrigeration. Keep perishables at 40°F (4°C) or below. Discard them after more than two hours above that temperature—or one hour when outdoor temperatures exceed 90°F (32°C). A cooler thermometer helps you check. USDA: camping food safety.
Recognize when someone needs more than a break
Check in with each other, especially during activity or when nights stay hot. Heat illness can develop even when someone has been drinking water.
Possible heat exhaustion
Heavy sweating, headache, nausea, dizziness, and weakness can be warning signs. Stop activity, move to a cooler place, loosen clothing, and cool the skin with wet cloths. Sip water if fully alert and able to swallow.
Seek medical help promptly for vomiting, worsening symptoms, or symptoms lasting more than an hour.
Possible heat stroke: emergency
Confusion, loss of consciousness, or severe illness with a very hot body requires emergency help. Skin may be dry or sweaty.
Call 911 or activate your emergency communicator. Move the person to a cooler location and begin rapid cooling with cool water or wet cloths while help is coming. Do not give drinks to someone with suspected heat stroke.
CDC: heat-related illness signs and first aid. Know your campsite’s location and how to summon help before you need it.

Make camp comfortable before the hottest hours
Get shade and water sorted early, leave room in the schedule for rest, and be willing to change plans. For car camping with an appropriate water source, compare countertop filtration options by capacity, transport needs, and the installed filters’ instructions.
