Area Forecast Discussion
National Weather Service Los Angeles/Oxnard CA
222pm PDT Wednesday July 22 2026

Synopsis
22/201 PM.

Hotter than normal conditions will continue through at least early next week, especially starting Thursday. The hot daytime and warm night conditions will bring elevated risks for heat illness. Thursday through Sunday will generally be the hottest of the next seven days. Gusty north winds will affect some areas through Friday.

Short Term - Today through Saturday
22/218 PM.

A huge area of high pressure, currently centered over north Texas and covering most of the southern half of the United States, will drive our weather well into next week. The core of the high will shift towards the west through Saturday and eventually settle over New Mexico and Arizona. Meanwhile, the mid-level flow will become more northerly by tomorrow while low-level onshore flow weakens. The building high pressure and shift in winds will drive a significant warm up that will really kick in Thursday. High temperatures of 97 to 107 will be common for most valleys and lower mountains by Friday, with highs of 85 to 95 over inland coastal areas. Being the hottest time of the year, most records look safe, but we might see a valley record or two fall. While beaches areas will only see highs in the 80s, the warmer than normal water temperatures will keep things muggy and unpleasant. Minimum temperatures will also be 5 to 10 degrees above normal overall, except 10 to 15 degrees above normal for the mountains and foothills. This means that the overnight relief that many depend on to cool their homes and their bodies will be less than usual. The one exception will be the Central Coast, where a shallow marine layer should keep temperatures warm but very moderated.

The suite of Heat Warnings and Advisories remain in play through Monday, with an emphasis on Thursday through Sunday. Decided to amplify the beaches heat message by having them all be under an Advisory through Monday (except for the Central Coast). One could justify some localized Warnings in the Advisory area for a day or two, but will continue the long-duration Advisory to simplify the message. The risk for heat illness is high, especially for sensitive groups like the very young, the very old, those without air conditioning, and those active outdoors.

There will be a little wind to deal with as well, mainly over southern Santa Barbara County, the I-5 Corridor, and the western Antelope Valley through Thursday or Friday Night. Expecting northwesterly to north gusts of 30 to 50 mph in those areas. A Wind Advisory remains in effect for tonight over southwest Santa Barbara County where the winds will be the strongest of the bunch. The winds weaken a touch Thursday night with a 30 percent chance of a Wind Advisory.

Mountain thunderstorm chances are not zero but low. The best window right now looks to be Friday and Saturday afternoons, but even then the thunderstorm chances are no higher than 10 percent.

Long Term - Sunday through Wednesday
22/221 PM.

The high pressure area will continue to dominate the southwest United States through most of next week. Little change to the heat expected from Saturday to Sunday, followed by a gradual and minor decrease in temperatures each day through Wednesday.

Marine
22/150 PM.

Widespread Small Craft Advisory (SCA) NW winds will develop this afternoon and will likely continue through the weekend across the Outer Waters. Seas will near 10 ft at times starting early Thursday. GALE WARNINGS have been issued for PZZ673/676 starting this evening through tonight. Local gusts may reach 35 kt across the southern portion of the Santa Barbara Channel this evening. Another chance (30%) of GALE Force winds Thurs afternoon & evening hours across the Outer Waters. SCA (Small Craft Advisory) winds will reach into the nearshore waters along the Central Coast and SB Channel at times through the forecast period.

Beaches
22/150 PM.

A long period, southern hemisphere swell will arrive later this week and will add to the continuing swell from Hurricane Fausto.

As a result, Beach Hazard Statements for Los Angeles and Ventura county coastlines remain in effect through the weekend. Refer to CFWLOX & SRFLOX for more details.

The Eastern Pacific looks to remain active over the next couple of weeks. This could result in additional southerly swells to impact the coastline.
