| Area Forecast Discussion National Weather Service San Diego CA 136pm PDT Tuesday Oct 28 2025 Synopsis Offshore flow and strengthening high pressure aloft will bring unseasonably warm conditions through Wednesday with periods of gusty Santa Ana winds along and below the coastal slopes of the mountains. The stronger gusts will be 35 to 45 mph today. The winds will be more localized for Wednesday morning with gusts of 25 to 35 mph. The marine layer will be very shallow with low clouds and fog limited to the immediate coast. Onshore flow returns by Thursday afternoon, spreading the cooler air inland on Friday along with a return of night and morning coastal low clouds and fog. High temperatures this weekend will be at least a few degrees warmer, followed by a cooling trend for early next week as high pressure weakens. For Extreme Southwestern California Including Orange... San Diego...Western Riverside and Southwestern San Bernardino Counties This afternoon...Surface pressure gradients remain offshore with 11.0 mb SAN-TPH. These gradients are currently supporting wind gusts of 25-45 mph, locally up to 53 mph in at least one of the wind-prone locations. The marine layer remains very shallow with only a few patches of low clouds and fog along the beaches of southern San Diego County. low clouds and fog may increase in coverage tonight over the coastal waters but the offshore flow will likely keep them from spreading inland beyond the beaches. Temperatures are as much as 20-25 degrees warmer than at this time in the coastal areas and inland valleys. From previous discussion... The upper level high pressure ridge covering the entire west coast northward into Canada will continue to build before weakening and shifting eastward over the Rockies late Wednesday in response to a shortwave trough moving inland over WA/OR. Offshore flow at the surface will peak today then begin to weaken Wednesday with onshore flow returning by Friday. The are peaking at this time. Weaker and more localized winds are expected for Wednesday morning, with the stronger gusts to 25 to 35 mph. High temperatures for today will be as much as 15 to 25 degrees warmer than on Monday for inland Orange County and the western Inland Empire, with additional warming on Wednesday of as much as 4 to 8 degrees for coastal areas of San Diego County. High temperatures for today for the coast and valleys will range from the lower to mid 70s near the coast to the lower to mid 90s for inland Orange County, western and southern portions of the Inland Empire and the inland San Diego County valleys near the coastal foothills to the mountains. High temperatures on Wednesday for the coast and valleys will range from the mid 70s to lower 80s near the coast to the lower to mid 90s for the valleys and inland Orange County. There are a few locations where daytime high temperatures could be near record levels on Wednesday, mainly for inland coastal areas and the western valleys. There are several locations for the coast and valleys into the mountains that could have record high minimum temperatures on Wednesday, especially if temperatures are slow to cool through late Wednesday evening in windy locations. High temperatures will begin to lower on Thursday with the greatest cooling of 4 to 8 degrees for coastal areas and the western San Diego County valleys as the offshore flow weakens and onshore flow begins to push marine air inland. The returning onshore flow will continue to spread cooler air inland on Friday with high temperatures around another 5 degrees cooler for the coast and valleys. High temperatures on Friday will range from around 70 near the coast to the lower to mid 80s for the inland valleys with the lower 90s for the lower deserts, around 4 to 8 degrees above average for inland areas. Low clouds and fog for coastal areas could return for late Thursday night into Friday morning, possibly in the form of dense fog with weak onshore flow beneath a strong and shallow marine layer inversion. High pressure aloft will bring warming for the weekend of at least a few degrees with high temperatures on Sunday ranging from the lower to mid 70s near the coast to the mid 80s to lower 90s for the Inland Empire with the lower to mid 90s for the lower deserts, around 8 to 12 degrees above average for inland areas. There will be a cooling trend beginning Monday as high pressure aloft weakens in response to a low pressure trough moving inland over WA/OR. Marine No hazardous marine conditions are expected through Sunday. Skywarn Skywarn activation is not requested. However weather spotters are encouraged to report significant weather conditions.
