Area Forecast Discussion
National Weather Service Los Angeles/Oxnard CA
736 PM PDT Tue Aug 5 2025

.SYNOPSIS...05/733 PM.

Temperatures will warm up to 4 to 8 degrees above normal
Wednesday and Thursday, especially away from the immediate coast.
Smoke from the Gifford fire will likely cause some air quality
issues at times. A slight cooling trend is expected over the
weekend but temperatures will remain above normal away from the
immediate coast well into next week.

.SHORT TERM (TUE-FRI)...05/736 PM.

***UPDATE***

Not much to mention this evening. The forecast remains on track.
Other than some high clouds and smoke from the Gifford Fire,
expect minimal clouds tonight into Wednesday. Low clouds are
likely to return to the Central Coast, including the Santa Ynez
Valley and the LA County coast around or a couple hours after
midnight. Additionally, there is a chance of low clouds over the
Oxnard Plain later tonight. Other than some sub- advisory
sundowners and gusty winds across the Antelope Valley & adjacent
foothills, benign conditions are expected through tonight.

Highs today were in the 80s to upper 90s away from the coast, with
70s along the coast south of Point Conception, and mainly 60s for
the Central Coast. Highs are expected to bump up 3 to 6 degrees on
Wednesday.

***From Previous Discussion***

The warming trend has begun on schedule and expected to continue
through Thursday with only very minor cooling Friday. Overall
highs today have been 2-4 degrees warmer than Monday and expecting
a similar increase Wed and again Thursday when highs will peak
around 104 in the warmer valleys, 100-106 in the AV, and 80s to
low 90s in the intermediate areas like Downtown LA, and interior
parts of the Central Coast. While these temperatures are 4-8
degrees above normal, that`s not quite enough to push heat risk
values into the advisory category so for now no heat advisories
are expected with this event. Coastal areas expected to stay in
the 60s and 70s with areas of low clouds and fog mainly in the
morning.

Overall mostly light winds through the period except for locally
breezy Sundowner winds across southwest Santa Barbara County the
next few evenings and typical afternoon and evening winds across
the AV. There will be some smoke impacts at times, especially
across Santa Barbara County and northern SLO County.

.LONG TERM (SAT-TUE)...05/221 PM.

And additional 2-5 degrees of cooling is expected Saturday as high
pressure aloft continues to weaken. This will bring temperatures
back to +/- 2 degrees of normal. After that, very little day to
day changes in the weather conditions across the area with the
usual night and morning low clouds for most coast and some lower
valleys. Most of the ensembles suggest near normal temperatures
through next week and possibly even into the following week with
no strong signals for a return of monsoon conditions. So overall
the first couple weeks of August look very quiet weather-wise

continue across the Outer Waters south of Point Conception through
Friday evening. Winds and seas are expected to remain below SCA
criteria over the weekend.

For the nearshore waters along the Central Coast, SCA level winds
will continue through late tonight. There is a 30-40% chance of
SCA level winds Wednesday afternoon/eve, and a 60% chance on
