San Diego is starting Sunday, September 27, under cloudy skies, with extensive cloud cover through the day as the high reaches 79. Rain is unlikely, with a 12% chance of precipitation, and northwest winds around 7 mph. Sunday night brings a low near 70.
Beach Hazards Arrive Before Monday’s Coastal Flooding
Beachgoers should take a pass on the water as elevated surf and strong rip currents affect the coast. The National Weather Service says waves will generally run 3 to 5 feet, with sets reaching 7 feet on some south-facing beaches. A Beach Hazards Statement remains in effect through late Sunday night, with minor tidal overflow and coastal erosion also possible.
A Coastal Flood Advisory begins at 5 a.m. Monday, September 28, and runs through 5 p.m. Wednesday, September 30, for coastal areas of San Diego and Orange counties. Morning high tides are expected to reach 6.7 to 7 feet, highest on Tuesday, with minor flooding possible in low-lying areas. Drivers should not go around barricades or through unknown-depth water, and swimmers should stay out of the surf while the hazards are in effect.
Monday Brings The Week’s Coolest Day
Monday will bring increasing sunshine and cooler conditions, with a high near 77 in San Diego and WNW winds around 11 mph. Breezier conditions are expected east of mountain passes and along desert slopes, while low clouds may return to much of the coastal basin Monday night.
Sunshine And Warmer Temperatures Return Tuesday
Tuesday turns warmer and dry, with a few low-80s readings possible at the coast. Highs reach 79 Wednesday and 81 Thursday, followed by sunny 88-degree afternoons Friday and 90 Saturday, while overnight lows generally stay in the upper 60s to low 70s.
For the coast, the biggest shift is from Sunday’s clouds and Monday’s cool-down to a warmer, drier stretch later in the week. Inland areas will heat up more sharply, with the broader region likely reaching the 90s and some desert locations approaching the upper 90s to low 100s by late week.
