The National Weather Service says that the huge swell pounding San Diego County beaches will last through Thursday, clouds will grow thicker, possibly bringing sprinkles, and the Santa Ana winds return with a whoosh on Friday.
There’s a low pressure system more than 1,000 miles to the south. But it won’t send heavy precipitation to San Diego, which has slipped below its seasonal average for rain by 0.20 inches. The city’s current total: 3.59 inches.
“We aren’t seeing any signals that there will be significant rain over the next week,” said Stefanie Sullivan, a weather service forecaster.
A swell out of the west produced 5-foot to 8-foot waves along much of the county’s coastline on Wednesday, and there were sets to 10-feet at spots like Windansea. The waves will largely remain in that range Thursday, generating hazardous rip currents.
San Diego’s daytime high will hit 69 on Thursday, 67 on Friday, 70 on Saturday, and 69 on Sunday. Julian will be cooler, reaching 59 on Thursday and Friday, 52 on Saturday and 57 on Sunday. The ocean will remain cool, with temperatures in the 56 to 59 degree range.
Forecasters say the Santa Anas will begin flowing through the region’s mountains Friday afternoon or evening, producing gusts upwards of 50 mph in some spots. The gusts will reach 25 mph to 30 mph in places like Ramona, Escondido and possibly Cardiff by the Sea.
The weather service isn’t planning a fire weather advisory because there’s lots of moisture left over from a series of storms in December.
