What Irvine's weather means for schools and clubs
Fall sports can open in real heat, with about 35 days a year at 90°F or above, so the first practice tees should be light and breathable even in a mild climate. Short sleeves cover March to December, from spring sports through the fall season, so a tee can carry most spirit wear sales. December lows average 43°F, so evening games in winter call for a hoodie in the stands even though afternoons stay mild. Rain is scarce, roughly 14 inches a year with several nearly dry months, so outdoor events can be planned with confidence, and caps are a safe add-on to every order.
