| Area Forecast Discussion ...UPDATED National Weather Service Los Angeles/Oxnard CA 417pm PDT Thu July 23 2026 Synopsis 23/851 AM. High pressure anchored over the West will keep a hot air mass in place through early next week. The hottest temperatures are expected for late this weekend and through the weekend. Elevated risk for heat stress and heat illness will continue as the prolonged hot daytime and warm overnight conditions are expected through Monday. Gusty northerly winds will continue affect portions of the area through Friday. Short Term - Today through Sunday 23/239 PM. A broad upper-level ridge of high pressure, currently centered over the Borderland region, is starting to shift westward this afternoon. The ridge will recenter into the Four Corners region for late week, allowing more influence of the high pressure system on the weather pattern across the southern California region. 500 mb heigheights are expected to climb and onshore flow will weaken some across the region over the next couple of days. The hottest days are expected today and Friday when the mix of high heigheights combine with weakening onshore pressure gradients. 950 mb temperatures will warm by a degree or two each day through Saturday. There is a moderate to high risk of heat illness over the next several days. A heat advisory remains in place for a majority of the coastal, valley, and mountain areas, while an extreme heat warning is in effect for the Antelope Valley floor. As the region sits on the edge of higher heat risk to the east, there is a moderate to high (30-50 percent) chance that localized extreme heat warning criteria could be met on Friday when the warmest temperatures are forecast. For those sensitive to the heat, such as the very young, the very old, those without air conditioning, and those active or working outdoors, the risk for heat illness is high. A tighter northwesterly surface difference across the state will bring another round of Sundowner winds across the region late this afternoon through tonight. Breezy to gusty northwest to north winds across southern Santa Barbara County will develop tonight with the strongest winds expected again across the southwestern portion of the county. Motorists driving on area roadways, especially on Highway 101 between Gaviota and Goleta, should be aware of gusty cross winds that could develop and make driving difficult. Long Term - Monday through Thursday 23/239 PM. High pressure aloft will shift back to the east early next week and allow for some cooling. Stronger onshore flow should develop and bring a return of night through morning low clouds and fog to the coastal areas. 500 mb heigheights drop into mid week next week. Enough cooling should develop to bring down the heat advisories by Monday. The main wrinkle could end being an easterly wave propagating under the ridge over the weekend. Some of the solutions push some moisture over the region, but the main question is enough energy will be present. A low but non-zero threat of monsoon convection will remain in the forecast over the mountains through the weekend. High pressure aloft will remain in place and keep above normal temperatures in place through next week. Another round heat could develop for the end of next week. Marine 23/1203 PM. Gale Force wind gusts will impact the outer waters this afternoon through late night, and there is a 30% chance of winds restrengthening to Gale Force levels each day across the outer waters north of the Channel Islands through Sunday. Otherwise, widespread Small Craft Advisory (SCA) NW winds will likely continue through the weekend across the Outer Waters, with seas nearing 10 ft at times. SCA (Small Craft Advisory) winds will spread into the nearshore waters along the Central Coast and Santa Barbara Channel at times through the forecast period. Beaches 23/1203 PM. A long period, southern hemisphere swell will arrive later this week and will add to the continuing swell from Hurricane Fausto. This swell will result in an increased risk of dangerous rip currents across the coastal beaches, as well as elevated surf of 3-6 ft across the Los Angeles and Ventura County Beaches. Therefore, Beach Hazard Statements are in effect through the weekend for Los Angeles and Ventura County beaches and the Central Coast beaches. Rip currents and elevated surf will be strongest across south to southwest facing beaches and harbors such as Avila Beach. The Eastern Pacific looks to remain active with tropical systems over the next couple of weeks. This could result in additional southerly swells to impact the coastline.
