KEY MESSAGES
Updated at 1200 PM PDT Wed Jun 24 2026
- Hazardous beach conditions along the Pacific Coast today
- An upper trough brings cooler temperatures, moisture, and a deeper marine layer for Friday and Saturday
- Gusty onshore winds begin Thursday, peaking Friday and Saturday with mountain passes gusting as high as 50-60 mph and marine concerns through the weekend
SHORT TERM
Issued at 1200 PM PDT Wed Jun 24 2026 (This evening through Thursday night)
As was the case yesterday, clouds have been slow to erode from inland areas this morning with satellite showing many coastal areas still socked in. Weak upper level ridging did compress the marine layer a bit, preventing it from stretching as far inland as it did Tuesday. Patchy fog was reported across multiple coastal sites this morning but visibility is quickly improving as an eddy just off the coast is helping to lift cloud bases. For areas that remain under cloud cover, temperatures today won't see much change from Tuesday's highs, generally remaining in the 70s and low 80s. For interior areas, the weak ridging will be enough to push temperatures into the upper 80s to low 90s today. Temps peak today with Minor HeatRisk for those warmer spots before a slow cooling trend begins Thursday.
The marine layer will remain relatively compressed tonight with additional patchy fog and visibility impacts for coastal terrain into Thursday morning. Upper level troughing will begin to push in by Thursday morning, with heights slowly falling through the day.
This is likely to limit interior warming for Thursday afternoon, with highs expected to be a few degrees cooler compared to today.
Around the same time, a large upper level low will sweep down the Canadian coastline, tightening the gradient over California. Gusty onshore winds will begin as early as Thursday, with the strongest winds expected for Friday and the weekend. Marine impacts/details from the uptick in winds can be found in the marine discussion below and in the Small Craft Advisory.
The long-period southerly swell will continue to impact the Pacific Coast beaches through this afternoon with a lull for the end of the week
High rip current risk with sneaker waves
never turn your back to the ocean! Additional beach hazards will be possible this weekended, please see additional details in the discussion below.
LONG TERM
Issued at 1200 PM PDT Wed Jun 24 2026 (Friday through next Tuesday)
A more significant cooldown will arrive Friday as heights continue to fall with the approaching low to the north. A frontal passage Friday could bring about 40-50+ mph winds for mountain passes and wind-prone spots, and 30-35 mph winds for the coastal waters. Low and mid-level moisture will surge in Friday as well, with a deepening marine layer and 50%+ min RH for every location except the very far interior spots. Drizzle and light rain will not be out of the question for both Friday and Saturday mornings given a sufficiently deep marine layer, and clouds may struggle to clear out Friday afternoon. Fire weather concerns will also be limited despite the strong winds given how high the humidity will be, along with excellent overnight recovery into Saturday morning.
Saturday will be the coolest day of the forecast period with ample moisture and a deep marine layer limiting daytime heating. Interior spots may be limited to the low 70s with 60s for most other locations and 50s right along the coast, around 10-15 degrees below normal. Cooler weather and gusty onshore winds prevail into Sunday, but the aforementioned low pivots northeastward and winds begin to weaken by Sunday evening. With the lows true departure on Monday, upper level ridging attempts to move back in but may face some push back. Ensemble members continue to trend more in favor with a troughing pattern prevailing into early week which would support a minimal to slow warming trend compared to the cooler weekend.
