Synopsis for the central california coast and bays including the Monterey bay - Greater farallones - .and cordell bank national marine sanctuaries - .
a compressed and shallow marine layer is currently hugging a majority of the coastline with a dense fog advisory in effect for Monterey bay through 10 am Saturday. Surface high pressure will allow for fair weather and moderate northwesterly breezes to prevail this weekend. Winds begin to increase Monday as surface high pressure over the eastern pacific ocean builds and moves east, keeping things dry and strengthening northwesterly winds to a fresh breeze status, particularly over the outer waters, north bay coast, and big sur coast. Significant wave heights will also begin building as a result at the start of next week.

SYNOPSIS
Issued at 134 AM PDT Sat May 11 2024
Warm temperatures continue inland today with highs from the upper 80s to lower 90s. Cooling has begun at the coast and spreads inland over the weekend into Monday with seasonal to warm temperatures through the next week. Areas of morning low clouds and fog are possible over the next few days.
SHORT TERM
(Today and tonight)
Issued at 134 AM PDT Sat May 11 2024
Moisture within a very shallow marine layer has brought areas of low stratus and dense fog to coastal portions of the region early this morning. Given reduced visibility on area webcams and observations a Dense Fog Advisory was issued for areas from SF south through Monterey Bay and down the Big Sur coast. Visibility values are bouncing around somewhat in places, but prepare for sudden changes if you have travel plans overnight. The advisory will continue through 10 AM this morning. Expect fog/stratus to retreat towards the coast thereafter with the marine layer keeping coastal/bayside temperatures cool this afternoon. It will be a different story inland as readings climb well into the 80s. The warmest locations will be within the North/East/South Bay Valleys and within southern interior Monterey and San Benito Counties, where a moderate HeatRisk will exist. This means that sensitive populations should take care and practice heat safety during the warmest (late morning - early evening) daytime hours. By tonight expect stratus/fog to redevelop along coastal areas with another chance for dense fog yet again into Sunday morning. Lows will be mostly in the 50s.
Here's some safety tips for hot temperatures:
* Stay hydrated and drink plenty of fluids.
* Wear lightweight, light-colored clothing.
* Reduce time spent outdoors or stay in the shade.
* Never leave people or pets unattended in vehicles.
* Use sunscreen if going to the coast or the pool.
LONG TERM
(Sunday through Friday)
Issued at 134 AM PDT Sat May 11 2024
The upper ridge will weaken with a slight cooling trend developing by early next week. Temperatures will moderate a bit for mid to late week with the trend of warmer temperatures inland and cooler temperatures along the coast continuing. In general look for highs in the 80s inland, 70s within the marine influenced valleys, and 60s on the beaches. Looking forward the latest climate outlook from the Climate Prediction Center suggests temperatures and precipitation should remain near seasonal averages between May 18th-24th.
AVIATION
(12Z TAFS)
Issued at 434 AM PDT Sat May 11 2024
Currently VFR at all terminals with the exception of SNS and STS as a compressed, shallow marine layer is hugging the coastline and protruding into the Bay, Monterey Bay, and Russian River Valley.
VFR through the TAF period at all terminals with the exception of MRY and SNS. Since OAK and SFO have yet to be impacted by a reduction to flight category thus far and the overall synoptic pattern is not changing much through the TAF period, there is uncertainty and low confidence on if the terminals will experience a reduction to flight category tonight. Widespread VFR and breezy onshore flow will prevail by this afternoon.
Vicinity of SFO...Currently VFR with breezy northwesterly flow.
There still remains uncertainty and low confidence on if the terminal will receive stratus this morning. The stratus is currently still holding tight to the coast and does not look to be expanding towards the terminal at this time. In addition, because the marine layer is compressed and shallower than 1,000 feet, it likely will not be able to feed through the San Bruno Gap. Winds will become breezy out of the west this afternoon. There is similarly uncertainty and low confidence on if the terminal will see a reduction to flight category tonight due to the fact that it has not yet materialized this morning and the overall synoptic pattern is not changing much through the TAF period.
SFO Bridge Approach...Similar to SFO.
Monterey Bay Terminals...Currently VFR and calm at MRY and LIFR with drainage flow at SNS. Winds will remain breezy out of the west/northwest through the TAF period. LIFR conditions are slated to plague both terminals again tonight.

BEACHES
Issued at 719 PM PDT Fri May 10 2024
Long period southwest swell will lead to slightly elevated chances for sneaker wave and rip current development this weekend.
Conditions are expected to stay below Beach Hazards Statement criteria as swell height will only be between 1-2 feet. However, in light of anomalously warm temperatures and increased likelihood of people traveling to the coast, visitors to the beach should remember to take safety precautions to prevent being caught by an unexpected large wave and to never turn your back on the ocean.
MTR WATCHES/WARNINGS/ADVISORIES
CA...Dense Fog Advisory until 10 AM PDT this morning for CAZ006-509- 528>530.
PZ...Dense Fog Advisory until 10 AM PDT this morning for Mry Bay.
