Last Map Update: Sun, Mar 15, 2026 at 3:28:43 am PDT

Moderate HeatRisk is expected Sunday through Wednesday with temperatures well above normal. To mitigate your risk: drink plenty of water or sports drink, do not leave children or pets in unattended vehicles, take frequent breaks in air conditioning or shade, and shift activities outdoors to cooler times of the day.
With well above normal temperatures and people flocking to the beach, it's important to know that even though the air will be hot, the ocean will remain cold. Remember to always wear your life jacket and never turn your back on the ocean!
Much above normal temperatures in the upper 80s to mid 90s are expected next week across the Bay Area and Central Coast. Portions of the interior Central Coast may reach the upper 90s starting mid to late week. Overnight lows in the upper 50s to low 60s will offer some relief to the lower elevations but will offer minimal relief within the higher elevations. Conditions will be much above normal along the coast next week but coastal residents may experience more relief overnight than those across the interior. The risk of heat related illnesses will increase with each additional day of heating from this event.
