Brutal Late-Summer Heat Wave Coming To San Diego County
By midweek it may be quite hot inland and warmer over coastal areas, despite the sea breezes.
SAN DIEGO, CA — High temperatures will keep Southern California baking all week long and into next weekend, prompting the National Weather Service Sunday to issue a heat advisory for the region.
"Days will be slightly hotter and nights a little warmer, with the resulting heat risk sufficient for a heat advisory for Monday through Wednesday," the NWS said.
The advisory runs until 8 p.m. Wednesday, but could be extended as the current forecast calls for high heat through next Sunday in several areas. The San Diego County deserts are expected to see highs near 110 degrees through next weekend, with highs in the low 90s in the valley areas.

"Drink plenty of fluids, stay in an air-conditioned room and stay out of the sun," the NWS stated.
The area was enjoying a respite Sunday before the mercury climbs. Developing low pressure along the West Coast was expected to continue to support onshore flow and a well-developed marine layer through Monday night, the NWS said. Low clouds should clear later Sunday morning, but spread well inland again Sunday night into Monday morning, forecasters said.

Warming will begin Monday as high pressure builds, the NWS said. By midweek it may be quite hot inland and warmer over coastal areas, despite the sea breezes.
A weak monsoon could return after midweek, but confidence in this pattern bringing any precipitation was low.
Swimming was expected to be hazardous at the beaches due to elevated surf and dangerous rip currents Sunday. A beach hazards statement was issued Sunday until 5 p.m. for San Diego County coastal areas.
High temperatures along the coast Sunday were predicted to be in the mid-70s with overnight lows in the mid-60s. Highs in the western valleys were expected to be around 80, and in the mid-80s near the foothills with lows in the lower 60s. Highs in the mountains were expected to be in the mid-80s with lows in the mid-60s and highs in the deserts were predicted to be 95 to 105 with lows in the mid-70s.
No hazardous marine weather was expected through Thursday.
