Area Forecast Discussion...UPDATED
National Weather Service Los Angeles/Oxnard CA
823 PM PDT Sun Jun 7 2026

.SYNOPSIS...07/456 PM.

A warming trend will begin Monday as high pressure starts to nudge
into the area from the west. Desert areas will reach triple digit
temperatures by mid week. Night and morning low clouds and fog
are still expected across most coast and some coastal valleys
through the week. skies will clear by afternoon in most areas
except some beaches will remain cloudy most of the day. Gusty
Sundowners are expected in western Santa Barbara County Monday
and Tuesday.

&&

.SHORT TERM (SUN-WED)...07/805 PM.

The upper level trough across the PNW responsible for the
relatively cooler weather will begin to break down ahead of an
upper level ridge gradually building in through mid-week.
Widespread warming will initiate Monday and continue through
Wednesday. Most notable warming will occur across coastal valleys
and interior areas, as coasts will still feel marine influences
due to moderate onshore flow. There is some uncertainty, however,
regarding how much temperatures will increase near the coasts on
Wednesday. Onshore LAX-DAG pressure gradients are projected to
drop rapidly to near neutral by Wednesday morning, which would
limit most if not all marine influences. This would result in a
fairly dramatic increase in temperatures at locations typically
moderated by marine air during this time of year. Warmest coastal
valleys can expect temperatures to reach the mid 90s by
Wednesday, but there remains a low (10 percent) chance for some of
the warmest spots to reach 100 degrees. There is a 20% chance for
Heat Advisories on Wednesday across some of the warmer valleys,
namely the southern Salinas, Santa Clarita, and western San
Fernando Valleys.

Wind advisories have been issued for northwest winds across the
Santa Barbara Southwest Coast and through the I-5 Corridor for
Monday night into early Tuesday morning. Slightly stronger
northwest flow Tuesday may prompt more wind advisories, with best
chances along the immediate Central Coasts, southwest Santa
Barbara County (west of HWY 154), and the interior mountains
(especially I-5 Corridor).

.LONG TERM (THU-SUN)...07/209 PM.

Very little change in the weather pattern is expected the latter
half of next week as high pressure aloft remains as well as a steady
onshore flow. Desert and other far inland areas immune from the
marine layer will remain quite hot and may actually warm up a
degree or two going into next weekend with around a 25% chance of
highs around 105. However, temperatures for coast and coastal
valleys should generally remain about the same as steady onshore
flow will keep temperatures within around 5 degrees of normal.

.AVIATION...07/2319Z.

At 2237Z at KLAX, the marine layer was 2000 feet deep. The top of
the inversion was 4900 feet with a maximum temperature of 17 C.

High confidence in VFR TAFs for KPRB, KPMD, and KWJF. 10% chance
for IFR cigs at KPRB between 10Z-17Z.

Low confidence in TAF for KSBP. 50% chance for no low clouds.
If clouds arrive, 50% chance for IFR cigs.

Moderate confidence in remaining TAFs. Good confidence in low
clouds arriving, except moderate for KSBP. Timing may be off +/- 2
hours. Good confidence in MVFR conds, except 30% chance for IFR at
KSMX.

KLAX...Moderate confidence in 00Z TAF. Timing of flight
category changes could be +/- 2 hours of current forecast, but
good confidence in MVFR conds being the lowest flight cat with
marine layer clouds through the period. Any east wind component
is expect to be less than 6 kt.

KBUR...Moderate confidence in 00Z TAF. Timing of flight cat
changes may be off +/- 3 hours, but good confidence in MVFR conds
with marine layer clouds.

.MARINE...07/814 PM.

For the Outer Waters, moderate to high confidence in current
forecast. High confidence in a combination of Small Craft
Advisory (SCA) level winds and seas through Thursday. Moderate
confidence in the GALE WARNING over the two northern outer zones
through tonight, with a 30-40% chance that the gale force gusts
are localized or only occur for a couple of hours. Monday and
Tuesday, there is a 30-50% chance of Gale force winds over the
southern two outer zones (PZZ-673 and PZZ-676) during the same
time period, with the best chances on Monday.  SCA winds are
likely to persist through Wednesday night, then weakening
Thursday through Friday.

For the Inner Waters north of Point Sal, moderate to high
confidence in current forecast. Through Wednesday, SCA level wind
are expected, mainly in the afternoon and evening hours, with
seas near or above SCA levels. On Thursday and Friday, winds and
seas are expected to remain below SCA levels.

For the Inner Waters south of Point Conception, moderate to high
confidence in current forecast. For a majority of the southern
Inner Waters, high confidence in winds and seas remaining below
SCA levels through Friday. The only exception will be the western
half of the Santa Barbara Channel, where there is a 40-60% chance
of SCA level winds Monday and Tuesday, mainly in the late
afternoon and evening hours.

&&

.BEACHES...07/808 PM.

A long period south swell will move through the waters Tuesday
through Thursday, with swell height building to 3 feet nearshore.
Periods will initially be 19 seconds, decreasing to 15 seconds by
Thursday. Surf is forecast to build to 3 to 6 feet with local sets
to 7 feet along south facing shores of Los Angeles and Ventura
Counties. There is a chance of more widespread surf of 4 to 7
feet with larger sets, in which case a high surf advisory will be
needed.

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