Satellite imagery depicts clear skies throughout the region this evening with some high clouds possible overnight. One thing to note for the medium term forecast: high resolution model guidance is picking up a possibility for a shallow marine layer to form Thursday night into Friday morning, interrupting the warming trend across the immediate coastal region. There is also a low to moderate confidence in fog and low stratus developing early Friday morning, with the impacts likewise confined to the immediate coastal region. The operations team will continue to investigate this possibility through the night into Thursday.

Sunny sky conditions prevail across the Bay Area and Central Coast this afternoon as high pressure from the west builds into the region. Coastal locations are a bit cooler and may not reach their forecast maximum temperatures this afternoon as a shallow marine layer and onshore flow remains in place at the coast. However, inland areas are likely to reach into the low-to-upper 70s with a few warmer inland spots approaching 80 degrees F. Overnight, mostly clear conditions will prevail as temperatures drop into the mid 40s to low 50s.
For Thursday afternoon, the warming trend continues across the interior with upper 70s to mid 80s as the high pressure aloft continues to build eastward. Again, there is only moderate confidence for coastal areas to reach their forecast maximum temperatures. This is as onshore flow and a shallow marine layer potentially limits the amount of daytime heating. Additionally, high clouds are forecast to stream inland across the region.

A subtle upper level shortwave through will temporarily put a pause on the warming trend Friday, yet temperatures will remain 5-15 degrees above seasonal averages. This will result in minor HeatRisk across much of the region through Saturday when more interior areas reach the upper 70s to mid 80s.
The high pressure will continue to build overhead the Bay Area and Central Coast by Sunday, Monday and Tuesday. Monday and Tuesday are likely to be the days in which we would issue Heat Advisories as HeatRisk rise to moderate levels, especially across the interior. However, we will continue to monitor this heat event as it approaches.
From previous forecaster: "Even with the uncertainty, global ensemble clusters illustrate that it is likely that we will be dealing with anomalously high heights through Thursday of next week. To put this into context, we will be in record breaking territory Sunday through Tuesday. This is not just with temperatures (read the CLIMATE section below), but monthly records for 850 mb temperatures and 500 mb heights which are both good indicators for the type of air mass that we are dealing with. Impacts wise, widespread minor HeatRisk on Saturday will give way to areas of moderate HeatRisk Sunday through Tuesday. To mitigate your risk: reduce time in the Sun during the warmest part of the day, stay hydrated with water, stay in a cool place during the heat of the day, move outdoor activities to cooler times of the day, and for those without a/c, use fans to keep air moving and open windows at night."
(06z TAFS) Issued at 955 PM PDT Wed Mar 11 2026
VFR through Thursday evening. Gentle northwest winds will become light and variable overnight before moderate onshore flow resumes Thursday afternoon. Towards and beyond the end of the 24-hour TAF period, monitoring the potential for a shallow marine layer to form late Thursday night into Friday morning. Stratus impacts could develop at the immediate coast, but the highest chance for stratus development lies early Friday morning, after the end of the 24-hour TAF period. There is also chance for stratus impacts to OAK and SJC, but confidence is not high enough to put ceilings in the TAFs at this time.
Vicinity of SFO, VFR through at least Thursday evening. Breezy northeast winds will become light after midnight before breezy onshore flow returns Thursday afternoon into the evening, possibly well into the overnight period. Towards the end of the TAF period, monitoring the potential for a shallow marine layer to form late Thursday night into Friday morning, with a low confidence for stratus impacts at the terminal.
SFO Bridge Approach, Similar to SFO.
Monterey Bay Terminals, VFR through Thursday evening. Light winds will persist through Thursday morning, with onshore flow returning during the afternoon. Monitoring the potential for a shallow marine layer to form late Thursday night into Friday morning. High resolution models are hinting at potential stratus impacts at MRY, but the timeframe of highest confidence lies beyond the TAF period.
(tonight through next Tuesday) Issued at 807 PM PDT Wed Mar 11 2026
Moderate to strong north breezes across the outer waters continue to cause rough seas. These winds last through the weekend with some of the inner waters being affected over the weekend itself. Winds and seas ease into the next work week.
Ca, None. PZ, Small Craft Advisory until 3 AM PDT Friday for Pigeon Pt to Pt Pinos 10-60 NM-Pt Arena to Pt Reyes 10-60 NM.
