Why worry about early season heat?

Widespread minor HeatRisk is expected through Saturday 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, leave windows open at night and/or use fans, and reduce activities outdoors and seek shade when possible.

Moderate HeatRisk is expected Sunday through Tuesday 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!

🌡️Why are we so worried about highs in the 80s and 90s? Because at this time of year, the body is not used to dealing with this level of heat, so these highs are more impactful now than they would be in July or August. Learn more about heat safety at https://www.weather.gov/safety/heat-ww #CAwx
