San Diego is waking up to clear skies, but the calm morning will give way to a dangerous heat surge Monday. The high is expected to reach near 99 degrees, with another warm night ahead as the city remains under an Extreme Heat Warning.
The National Weather Service San Diego says the warning covers coastal San Diego County through 8 p.m. Thursday, October 8. Highs across coastal areas and nearby higher terrain will range from the mid-80s to around 100, while overnight lows remain unusually warm in the upper 60s to mid-70s.
Heat Eases Slowly After Monday
Tuesday will remain hot with a high near 97 and mostly sunny skies, followed by a high near 92 on Wednesday and Thursday. Aviation conditions are forecast to remain clear and VFR, with local easterly breezes through 20Z and gusts to 25 knots in foothills and eastern valleys.
A gradual cooldown arrives Friday, when the high is forecast near 86, followed by 83 on Saturday and 78 on Sunday. The cooler stretch will be welcome, but the heat warning remains in effect through Thursday, so San Diegans should continue limiting time in direct sun, drinking plenty of fluids and checking on vulnerable neighbors.
Beach Hazards Begin Tuesday Afternoon
A Beach Hazards Statement is in effect from Tuesday afternoon through Friday evening for San Diego County coastal areas. The National Weather Service expects 3- to 5-foot surf on south- and southwest-facing beaches, dangerous rip currents and a chance of minor coastal flooding or erosion around evening high tides.
Evening tides could reach 6.5 to 7 feet during the statement period. Anyone heading into or near the water should use extra caution, especially as beach conditions become more hazardous than the sunny skies might suggest.
Weekend Cooling Continues
The forecast otherwise points to a continued cooldown into the weekend after the early-October heat spike.
