The National Weather Service is forecasting a "roller coaster" of temperature change in the next six days for Northern California, but it starts with some very warm and pleasant weather Wednesday to Friday.
Prepare for a mini April heatwave in the next several days, with Thursday looking to be the hottest day around the Bay — with predictions of likely record-topping temperatures in some spots. The heatwave will especially impact inland parts of California, all up and down the state, with the Central Valley expected to see highs around 97 degrees on Thursday.
San Francisco is likely to see mid-80s on Thursday, and parts of Napa, Sonoma, and the East Bay should see highs in the low 90s.
We aren't going to let you forget about the upcoming heat! 🌡️ Temperatures will warm up on Wednesday, peak on Thursday and remain warm into Friday. Interior areas are likely to see temperatures exceed 90°F. Be sure to check on those most vulnerable! #CAheat @BayAreaWX #CAwx pic.twitter.com/DibeSs6ZZ8— NWS Bay Area 🌉 (@NWSBayArea) April 5, 2022
All that crazy heat is going to be followed by a pretty quick cooldown, though, by next week. At least the weekend will remain warm-ish, but expect some unseasonably chilly temps to hit by Monday, when the National Weather Service is predicting a high of 58 in SF — at least a 20-degree swing from Thursday.
Who likes roller coasters?🙋♂️🎢 Take a look at these forecast temperature traces. Mini heat wave🥵 later this week, but much colder weather returns early next week. Visit https://t.co/W1YfxSzLcY for your local forecast #cawx pic.twitter.com/0mGMuGY8gt— NWS Bay Area 🌉 (@NWSBayArea) April 5, 2022
The Apple Weather app has Monday's high at 51 in SF, with a low of 44 and windy conditions predicted. On Tuesday it gets even chillier, with a low of 42, and things get only moderately less cold by mid-week next week.
This week, though, the beach may not be the best idea, at least until Thursday. Through Wednesday night, you should be extremely careful if you're planning to head to the beach, as the NWS is also predicting sneaker waves and rip currents. They're advising everyone to basically not go near the water or stand on any rocks at the water's edge.
A moderate swell with period 14 to 16 seconds with swell heights over 11 feet will arrive overnight.— NWS Bay Area 🌉 (@NWSBayArea) April 4, 2022
This will increase the risk for rip currents and sneaker waves from 3 AM PDT Tuesday through 9 PM Wednesday
Larger breaking waves in the surf zone is possible#CAwx #CAbeaches pic.twitter.com/x6VtasXnIZ
