If you can avoid it, stay out of the sun when it is at its hottest. The hours from 10 a.m. to 4 p.m. are the most intense during the summer months. Try, if you can, to do your activities earlier or later than these hours. Keep shade around, and if there isn’t natural shade bring umbrellas or tents to activities. Remember to always wear a solid SPF. Adults can do well with 30+ strength, while kids should have at least 50+ strength.
