Going to Indio next weekend. Will be playing Westin Mission Hills Pete Dye course and PGA West Stadium course. Luckily I snagged early am tee times, however, temps will be 100+ during peak time. Thin and light colored clothes, plenty of sun screen, a cold neck towel, water and a cooler with lots of ice will do the trick. I go almost every year in August to celebrate my birthday with my brother and two cousins.
