An atmospheric river will bring significant rain to Northern California Monday and Tuesday but entirely miss San Diego County, which is days away from wrapping up an otherwise wet year, the National Weather Service said.
But there will be a slight chill to the air along the San Diego coastline — the kind that reminds people that it’s a good idea to keep a sweater handy. And you’ll need your winter wetsuit before long.
San Diego’s daytime high will be 73 on Monday, 74 on Tuesday, 75 on Wednesday, 73 on Thursday and 71 (or lower) on Friday, when light rain also is possible, the weather service said. The seasonal daytime high is 77.
The air will turn cooler partly because a coastal eddy will form on Wednesday night and send lots of cool, moisture air to the coast and into some inland valleys. The marine layer will thicken, and some areas could get fog late Wednesday and early Thursday.
Elevated surf also is expected on Wednesday and Thursday, causing strong rip currents in many areas. Sea surface temperatures are in the 65-to-70-degree range. They’ll soon start to dip.
