Consider the group, not only the temperature

National Weather Service guidance notes that heat can affect anyone, with greater vulnerability for some people including young children, older adults and people with certain medical conditions. Match the day to everyone attending. Follow individual medical advice where relevant.
Check what shade actually means

A campsite photograph may show shade at a different time of day. Ask about tree cover, access to a cooled building and the distance to reliable drinking water. A sun shelter is not an air-conditioned refuge.

Check the forecast for the place you will actually camp.
Keep the schedule flexible

- Move optional activity to a more suitable part of the day.
- Plan a shorter route and a clear return option.
- Keep drinking water available and follow personal fluid advice.
- Build in rest and a place to cool down.
- Change or cancel plans if conditions exceed the group’s ability to stay well.
Prepare before someone feels unwell
Read the official heat-illness information linked below and know how to reach emergency help. Do not treat confusion, collapse or severe symptoms as ordinary tiredness. Do not use a parked vehicle as a waiting place for a child or pet.
