What Irvine's weather means for sports teams
Irvine gets about 35 days a year at 90°F or more, so summer camps and tournaments need wicking tees and caps even though the rest of the year is gentle. Evenings turn cool, with December lows averaging 43°F, so a warmup hoodie for night games and early-morning tournaments still belongs on the order. Average highs reach 70°F or more in 10 months, March to December, which leaves short-sleeve practice kits in use for most of the year. At about 14 inches of rain a year, games are seldom rained out, so sun cover matters: caps for players and coaches, and lightweight long sleeves for long tournament days.

When do teams in Irvine need warmup gear?
Mainly after dark in winter. Even January, Irvine's coolest month, keeps afternoon highs near 68°F, but winter nights are another matter, so plan one warmup hoodie per player for late games and a jacket for each coach.
