What Riverside's weather means for schools and clubs
Riverside sees 90°F or more on about 101 days a year, and fall sports usually start in that heat, so practice tees and the first spirit wear order should be light and breathable. Average highs never fall below 67°F, reached in December, so spirit wear leans on tees and caps all year, with hoodies mainly for evening games. Tee weather, a 70°F average high or warmer, runs March to November, so graduation shirts and most of the spring sports season land in short-sleeve weather. Roughly 22 days a year hit 100°F, so early-season practice gear should be light-colored performance fabric, and caps belong in the team order. With about 9.4 inches of rain a year, rain dates are rarely needed for outdoor fundraisers and fun runs, so put the effort into sun cover: caps, visors and light colors.
