Weather & seasonal safety
San Joaquin County has real weather extremes: triple-digit Central Valley heat in summer and cold, foggy nights in winter. Both can be dangerous if you’re unsheltered. Call 2-1-1 (or 1-800-436-9997) to find which sites are activated near you — cooling and warming locations open and close with the forecast.
Stay cool, hydrated, and out of the sun
Summer afternoons in Stockton routinely reach 95–105°F. During extreme-heat events, the county and cities open cooling centers (often libraries and senior/community centers) and 211 keeps the current list. Day centers below offer water, shade, and a place to rest.
