| Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 209pm PDT Monday Oct 12 2026 Synopsis 12/205 PM. Minor to moderate coastal flooding is likely continue to through at least Tuesday. Beginning Tuesday and continuing through the end of the week, moderate to strong offshore flow will bring warm and dry conditions to the area. Short Term - Today through Thursday 12/204 PM. A highly amplified upper level pattern has developed over the eastern Pacific and it appears southwest California will be experiencing quite a range of temperatures and weather conditions over the next couple of weeks. The upper low over the area yesterday and today that has brought scattered light showers and much cooler temperatures will evolve into our first real Santa Ana wind event of the season later in the week. For today though, highs will mostly be in the 60s which is 10-20 degrees below with some off and on light showers, mainly in the morning. As the upper low slowly moves into the Great Basin, onshore pressure gradients will be weakening and a light northeast flow aloft will develop over the area as early as Tuesday afternoon. Not expecting any winds of significance Tuesday but high temperatures will warm up 4-8 degrees area-wide as the air mass dries out and heigheights rise at least 10dam. Wednesday will be noticeably warmer and drier as offshore gradients continue to increase across the area heigheights climb another 10dam. Still not expecting any significant winds yet except possibly some northeast winds in the San Gabriel mountains up to 40 mph. Santa Ana winds will really pick up Thursday into Friday as all the ingredients appear be in place and properly aligned. We have above normal confidence in moderate to strong Santa Ana winds during this timeframe. The latest ensemble pressure gradients indicate that the peak offshore gradient will occur Friday morning somewhere in the 5-7 mb range. Couple that with 50kt winds at 850 mb and very strong upper level subsidence, that should result in peak winds of 50-70 mph in the San Gabriel mountains and 35-55mph across the LA/Ventura valleys as well as the Ventura County coastal areas and Santa Monica mountains. This will likely be a hot and dry Santa Ana, so large and fast moving fires are a concern heading into this time frame. As a reminder, Santa Ana winds typically do not impact the LA Metro area and LA coast. Temperatures will be peaking during these days as well with highs in the upper 80s and 90s across all coast and valleys, including the Central Coast. There is a very strong chance (60-80%) that heat advisories will be needed for coastal areas and perhaps some coastal valleys areas starting as early as Thursday and especially into Friday. Long Term - Friday through Monday 12/208 PM. One more day of gusty Santa Ana winds are possible (30-40 percent chance of reaching advisory levels) into Saturday, taking on a more easterly orientation. Temperatures are expected to remain well above normal through Sunday, but slowly cooling into next week. And looking out a little further there is fairly high agreement in the models that another cold upper low will move into the area the middle of next week, for another big swing into temperatures and weather conditions. It looks like mainly a dry system at this point, but there is some potential is tracks just enough offshore to support some shower activity. Marine 12/1211 PM. For the Outer Waters, moderate to high confidence in current forecast. Through this afternoon, high confidence Small Craft Advisory (SCA) level seas subsiding below advisory levels by the evening, with winds below SCA (Small Craft Advisory) levels except for near Point Conception in Zone PZZ673. On Tuesday, there is a 40-60% chance of SCA (Small Craft Advisory) level winds, again mainly around Point Conception. For Wednesday through Thursday, high confidence in winds and seas remaining below SCA (Small Craft Advisory) levels. For the Inner Waters north of Point Sal, moderate to high confidence in current forecast. High confidence in winds and seas remaining below SCA (Small Craft Advisory) levels today. For Tuesday through Thursday, there is a 30-40% chance of SCA (Small Craft Advisory) level winds in the afternoon and evening hours, except a 50% chance Wednesday evening. For the Inner Waters south of Point Conception, moderate confidence in current forecast. Through Wednesday, high confidence in winds and seas remaining below SCA (Small Craft Advisory) levels for most area, but the only exception is the western half of the Santa Barbara Channel where there is a 50% chance of SCA (Small Craft Advisory) level winds Tuesday afternoon and evening. On Thursday and Friday, there is a 40-50% chance of SCA (Small Craft Advisory) level northeast winds from Ventura south to Santa Monica. Long period swell from the west and the south are affecting the coastal waters, and can create a confused sea state. This can make boating more challenging and dangerous, especially for small vessels. Beaches 12/1203 PM. While the peak timing for the most impactful coastal flooding has passed, there is still a threat of minor to moderate coastal flooding through Tuesday, due to continued high tides and elevated to high surf. The highest tides will occur during the mornings and range from 7.0 to 7.5 feet through Tuesday, with secondary high tides during the evenings (around 6 feet tonight decreasing to 5 feet by Tuesday evening). As for elevated surf, a long period southerly swell and long period westerly swell will impact the coastal waters the next several days. The Coastal Flood Advisory for the San Luis Obispo and Santa Barbara coasts are in effect until this evening, and the rest of the coasts continuing until Tuesday afternoon. The High Surf Advisory for the Central Coast beaches (surf 8-12 feet) is in effect until this evening. The Beach Hazards Statement for Santa Barbara South Coast will continue into Tuesday afternoon as well, and is due to elevated surf and minor tidal overflow during high tides (lingering after the coastal flood advisory expires). A Beach Hazards Statement Tuesday through Thursday morning will likely be issued following the Coastal Flood Advisory expiration on Tuesday for the LA/Ventura County Beaches. This is due to minor tidal overflow continuing to be possible during morning high tides (remaining around 6.5 feet) and the 2 foot 15-16 second southerly swell continuing to impact the area. Please continue to monitor the forecast and refer to the Coastal Hazard Product (CFWLOX) for more information.
