...UPDATED National Weather Service Los Angeles/Oxnard CA
533pm PDT Tuesday May 19 2026

Synopsis
19/114 PM.

Light offshore flow will continue through Wednesday leading to clear skies and warm temperatures. Beginning Thursday there will be a return to cooling May Grey conditions which will last through the weekend.

Short Term - Today through Friday
19/159 PM.

Very little change to the previous forecasts through the rest of this week. Temperatures will peak Wednesday, generally 1-3 degrees warmer than today, except around 5 degrees warmer in the Antelope Valley. Light offshore flow will start the day but will turn onshore by afternoon or sooner at the coast. Warmer valleys will reach the lower 90s while areas towards the coast will be in the 70s and 80s. These are roughly 5-10 degrees above normal.

While the upper level pattern remains more or less the same through the rest of the week, the primary change will be the reversal from offshore to onshore flow beginning Thursday which will bring temperatures back down to near normal levels by the weekend. This will also coincide with a return of the marine layer, as early as Thursday in some areas but possibly not til Friday or Saturday for the valleys.

One exception to this may be southwest Santa Barbara County where a 2-4mb offshore gradient during the overnight hours will likely create nightly Sundowners with winds gusting between 25 and 40 mph at times, particularly Wednesday and Thursday nights.

Long Term - Saturday through Tuesday
19/209 PM.

The rest of the 7 day forecast into early next week is very benign as the baggy trough will persist with moderate to strong onshore flow through the period. This is likely to maintain temperatures near to slightly below normal temperatures with a steady dose of night and morning low clouds and fog covering most coast and valley areas.

And once again there is the possible exception across southwestern Santa Barbara County where offshore flow returns Monday night with gusty north winds at times.

Marine
19/203 PM.

For the Outer Waters, high confidence in current forecast. Today through Friday, winds and seas are expected to remain below SCA (Small Craft Advisory) levels, except for localized pockets of near SCA (Small Craft Advisory) NW winds during the afternoons and evenings. Chances of issuing an advisory is fairly low.

For the Inner Waters north of Point Sal, high confidence in current forecast. Localized near SCA (Small Craft Advisory) winds are possible south of Port San Luis Wednesday afternoon through early evening. Otherwise, winds & seas are expected to remain below SCA (Small Craft Advisory) levels through Friday.

For the Inner Waters south of Point Conception, high confidence in current forecast. Local SCA (Small Craft Advisory) winds may occur again later today and Wednesday evening off the coast of Point Dume, across the San Pedro Channel, and in the Santa Barbara Channel. Otherwise through Friday, winds and seas are expected to remain below SCA (Small Craft Advisory) levels.
