1. Keep Your Tent Cool
Pay attention to the slant of your tent or camper van when you orient it in a campsite: where is the sun’s natural arc in relation to its position? It’s ideal, in hot locations, to ensure your tent is in the shade for at least part of the day to keep it cool, and that it can be opened to allow the circulation of cooler air and stop stuffiness.
Stock your campervan or tent with portable, battery-run fans to help you through still nights, and remember that privacy screens can also act as good bug screens if your tent doesn’t come fitted with mosquito protection. Yes, you still need to put down that groundsheet; just because the weather is hot doesn’t mean it won’t get damp and cold overnight.
You’ll also want to sleep with the right materials to make sure you don’t wake up a sweaty mess. If you only have a winter or cold-weather sleeping bag, it’s a good idea to invest in another, lighter one to keep you insulated but not over-heated.
