I have often talked to some people, posting on Facebook and in discussion, about how I survive hiking in hot weather. From small, local San Diego hikes to the Grand Canyon where I faced temperatures over 100 degrees Fahrenheit, to one day on a Pacific Crest Trail section hike where temperatures were over 110 degrees Fahrenheit with no shade in sight for many miles. Through all of this, I’ve picked up a lot of techniques, which I have practiced and modified, and continue to practice and modify. As this knowledge is useful, I am writing this post to describe some of what I have learned.
