Wear a gardening/fishing type hat, wear long sleeve shirts that are cool breathing, and wear jeans/pants throughout the summer. I was out gardening for 7 hours straight this past Sunday in 86 degree weather with high UV index and by wearing the type of clothing to cover your skin you'll be able to stay out for hours without burning. Also you'll of course want to take measured breaks and cool downs. Look at how people have to dress in middle-Eastern countries for a reference point. Keep most the skin covered. This way, you may only need to apply any sunscreen to the tops of the hands/fingers.
