| Area Forecast Discussion National Weather Service San Diego CA 232am PST Tuesday Nov 3 2026 Synopsis Fair and cool weather will continue through Thursday. Except there is a slight chance of showers mainly in southwest San Diego County tonight. High pressure aloft and offshore flow will bring gradually warmer and dry weather Thursday into the weekend. For this weekend, temperatures will climb well above normal, especially near the coast, and offshore breezes and locally stronger Santa Ana winds are likely for foothills and some inland valleys. For Extreme Southwestern California Including Orange... San Diego...Western Riverside and Southwestern San Bernardino Counties It's a mostly clear and tranquil morning, with a few high clouds floating by and a few low clouds off the coast. A low pressure trough zipping west to east through northern CA will bring more high clouds today and more low clouds tonight into Wednesday. In fact, the low clouds could generate a few light showers in southwest San Diego County this evening through about sunrise Wednesday. This trough will also enhance onshore winds in the coastal waters, the mountains, and the deserts mainly this evening. Isolated strongest gusts should reach around 35-40 mph in the mountains and deserts. The trough exits to the east but it is followed by only timid high pressure and some very weak offshore flow. A high pressure ridge over the West Coast amplifies on Friday and Saturday. This will boost temperatures by virtue of the higher pressure, but also from stronger offshore flow, which will favor the warming closer to the coast. That offshore flow will produce some winds, maybe some legit Santa Ana winds, in foothills and some adjacent valleys. Offshore winds right now look most likely and strongest on Saturday and Sunday mornings, when top gusts could reach 40 mph. This is a rough estimate for now, and the wind picture will become clearer in coming days. High temperatures Saturday and Sunday near the coast and in western valleys will soar well into the 80s, about 5-15 degrees above normal. That will produce a moderate HeatRisk in those areas. However, the air will be dry, allowing for efficient cooling during the long nights, especially where winds calm. All this will mitigate the heat risks. The ridge aloft and the offshore flow begin to weaken by Monday as a strong jet drives a longwave trough eastward across the Pacific. Marine Weak winds expected tonight through this morning, before onshore winds strengthen into this afternoon and evening, with gusts in the outer coastal waters 20 to 25 knots through early Wednesday morning. Winds will lead to rough, choppy seas. A Small Craft Advisory for this hazard is in effect this afternoon through early morning Wednesday. Beaches Tides will increase at the end of the week, reaching 7 ft as early as Thursday in Orange County and Friday in San Diego County. Tides will peak over the weekend into early next week at 7.5-7.7 ft. Minor coastal flooding is possible. We're monitoring the potential for an incoming west swell of 3 ft from 290 with a 14-16 second period. If this swell materializes, max surf of 6 to 7 feet are possible, which would increase the flood potential on west facing beaches. Reminder, tides mentioned have been corrected to reflect the current trends in actual tide observations. Skywarn Skywarn activation is not requested. However weather spotters are encouraged to report significant weather conditions. NOAA San Diego CA Office: Watches - Warnings - Advisories CA...None. PZ...Small Craft Advisory from 1pm this afternoon to 4am PST Wednesday for Waters from San Mateo Point to the Mexican Border Extending 10 to 60 nm out including San Clemente Island. |
