Area Forecast Discussion...UPDATED
National Weather Service Los Angeles/Oxnard CA
918 AM PDT Wed Jun 10 2026

.SYNOPSIS...10/356 AM.

Temperatures will rise to up to 15 degrees above early June
normals today. Then highs will remain warm through Friday, except
for a large cool down Thursday along the Central Coast. A slow
but gradual cooling trend is likely this weekend into early next
week. Expect minimal marine layer clouds today and Thursday,
before becoming more widespread through the weekend.

&&

.SHORT TERM (TDY-FRI)...10/917 AM.

***UPDATE***

Northerly winds reached advisory levels once again across the
Southwest Santa Barbara Coast, Western Santa Ynez Range, and down
the I-5 Corridor last night into early this morning. Winds have
since subsided and will remain below advisory levels through the
end of the week.

Marine layer cloud coverage was sparse this morning as expected
with stratus limited to the LA County Coast and over coastal
waters. A rogue patch of stratus was also seen over the Ventura
County Mountains. All low clouds seen over LA County and the
Ventura County Mountains earlier this morning have since burned
off.

The forecast remains on track for a significant warmup today
thanks to weakening onshore flow and strengthening high pressure
over the region. Afternoon highs will climb to 10-18 degrees
above normal for early June. Heat Advisories remain in effect for
the interior coasts of Santa Barbara and San Luis Obispo Counties.

***From Previous Discussion***

A significant warmup is expected today, as onshore flow weakens
and high pressure builds over the area. Breezy offshore winds are
expected through this morning across the higher terrain in San
Luis Obispo and Santa Barbara Counties. As a result of these
downsloping winds, the warming temperatures will be most
noticeable along the Central Coast. Heat Advisories have been
issued for the interior coasts of Santa Barbara and San Luis
Obispo counties today. High temps are expected to reach 12-18
degrees above normal for the areas in the Heat Advisory, and
elsewhere will commonly see up to 10 degrees above normal for
early June. While the inland extent of marine layer stratus and
fog will be minimal this morning, stratus and patchy fog will
remain possible over the immediate coasts and coastal waters.

Warm conditions will continue into Thursday and Friday for most
locations with the exception of the Central Coast, where
increasing onshore flow will drive a decrease in temperatures to
close out the week. There is a low chance (5% chance) of a shower
or thunderstorm developing over southern portion of the forecast
area, particularly the eastern San Gabriel mountains Friday and
Saturday afternoon and evening. PWATs may increase to near 1-inch
as a weak upper low is favored to shuttle mid-level moisture into
the region from the southeast.

.LONG TERM (SAT-TUE)...10/355 AM.

This weekend into early next week, minimal changes in the weather
pattern are expected each day. Temperatures will very gradually
trend cooler, and consistent onshore flow will maintain areas of
marine layer stratus and fog each morning. The synoptic pattern
favors moderate riding over the area, thus temperatures inland
will be several degrees above normal. Coast and valley areas will
be under the influence of the onshore flow and marine layer
clouds (nature`s air conditioning) thus temperatures will be near
(if not slightly below) normal. Like Friday, there is a small
chance for a shower or thunderstorm over the eastern San Gabriel
Mountains Saturday afternoon through evening.

.AVIATION...10/1059Z.

At 0719Z at KLAX, the marine layer was about 1500 ft deep. The
inversion top was at 2900 ft with a maximum temperature of 21 C.

High confidence in VFR TAFs for KPMD and KWJF, but winds may be
off by 5 kt at times.

Moderate to low confidence in remaining TAFs. There is a 20%
chance of cigs at KSMO, and KLAX between 13Z-15Z Wed, and a 60%
chance at KLGB.

KLAX...Moderate confidence in TAF. Timing of flight category
changes could be +/- 3 hours of current forecast, and there is a
20% chance of BKN005 to BKN015 cigs between 13Z-15Z Wed. Any east
wind component is expect to be less than 6 kt.

KBUR... High confidence in TAF.

&&

.MARINE...10/854 AM.

Good confidence in Small Craft Advisory (SCA) level winds and seas
over the waters along the Central Coast and out 60 NM from shore
(and beyond) through at least tonight, with 10 foot seas beyond 30
NM from shore possibly lingering into Thursday morning. Southerly
winds 10-20 knots are likely late Wednesday south of Point
Conception, expanding north through Thursday. Then conditions are
expected to be relatively mild through early next week for much
of the coastal waters.

However, west to northwest wind gusts 15-20 knots (locally 25
knots) will be common each afternoon through early evening Friday
through at least early next week across the nearshore waters
south of Point Conception (including the Santa Barbara Channel,
San Pedro Channel, and Santa Monica Bay).

&&

.BEACHES...10/400 AM.

A High Surf Advisory is in effect for beaches along Malibu
through Thursday. At 1 PM PDT Tuesday, latest report from Zuma
indicated swell height around 7 to 10 feet at 19 seconds. A Beach
Hazard Statement remain in effect for the Ventura County Beaches
through Thursday evening. A long period south swell will continue
to move through the waters Today through Thursday, with swell
height building to 3 feet nearshore. Periods around 20 seconds,
decreasing to 15 seconds by Thursday. Surf is forecast to build to
4 to 7 feet with local sets to 7 to 10 feet along south facing
shores of Los Angeles County Beaches, and 3 to 6 feet for Ventura
County Beaches.

Hazardous surfing and swimming conditions are expected due to the
building surf, along with strong rip currents.
