Weather: Tustin Irvine Ranch station, 2 mi from Irvine's center (NOAA 1991-2020 Climate Normals). People: Census ACS 2020-2024. Counts: CBP 2023, by county, paid-employee establishments. Population: Census, July 2025.
What Irvine's weather means for gyms
Summer gets warm, with about 35 days a year at 90°F or more, so a tank and a light performance tee earn real rack space alongside the member tee. Winter never gets cool enough here to pull tanks off the rack, so fleece stays a light, small order. At about 14 inches of rain a year, a park workout or outdoor bootcamp is rarely rained out, and a cap earns a place on the rack.
