Here is this week’s weather forecast by PG&E meteorologist John Lindsey.
A prolonged heat event, especially across the inland valleys, is expected to continue through the upcoming week as high pressure over the southwestern United States strengthens and expands. Today’s high temperatures will reach triple digits in the inland valleys and mid-80s in the coastal valleys. Highs at the beaches will range from the mid- to high 60s.
Along the beaches, gentle southerly winds will bring coastal low clouds from the Southern California Bight as a Catalina Eddy continues to develop. The marine layer will deepen on Monday into Friday and will move farther inland during the night-morning hours. This condition combined with persistent onshore winds will keep the coastal regions relatively cool. However, inland temperatures will remain in the triple digits through Thursday. Further inland, Bakersfield is forecast to hit 113 on Tuesday, which would break the previous record of 107 degrees set back in 1947.
A downward trend in temperatures looks to start around Friday, but above-normal temperatures will remain through next weekend.
This morning’s 4- to 6-foot northwesterly (310-degree, deep-water) swell (with an 8- to 11-second period) will remain at this height into Monday night.
A 7- to 9-foot northwesterly (310-degree, deep-water) sea and swell (with a 5- to 11-second period) is forecast along our coastline Tuesday through Wednesday, becoming a 6- to 8-foot northwesterly (300-degree, deep-water) swell (with an 8- to 11-second period) along our coastline Thursday, decreasing to 5 to 7 feet by Friday.
A 3- to 5-foot northwesterly (310-degree, deep-water) sea and swell (with a 5- to 11-second period) is expected along our coastline Saturday into next Monday.
Arriving from the Southern Hemisphere: A significant Southern Hemisphere swell is forecast to arrive along the California coastline Tuesday into Thursday. However, its incoming direction is 165 degrees, and it’s too far south-southeast to have much effect along the San Luis Obispo and northern Santa Barbara County coastlines.
Ocean waters will range between 52 and 54 degrees through Saturday.
