If you plan on hiking in hot weather, freeze your water bottles the night before. In addition to hydration, the cold bottles held against your skin can help cool you down.
Sunscreen is a necessity – don’t forget to apply it on your neck and ears. A floppy, wide brim hat protects the neck & ears much better than a baseball cap. Sunglasses are great for protecting your eyes from the sun.
Bring cooling towels to put around your neck and keep them wet. It’s very refreshing to wipe your face, arms and legs with them when you start getting too hot.
Hot weather hiking takes a lot of energy and strength, so bring extra food. Don’t be in a hurry. Take lots of breaks. Relax, have a sip of water or some food. Dip your feet in a creek or even take a swim.
Your feet might sweat more when it’s hot. Wear a light pair of socks that wick away moisture and wear a pair of hiking socks on top.
It’s always good in hot weather to take someone with you hiking and let others know where you are going and when you plan on returning in case of an emergency.
