Synopsis for the central california coast and bays including the Monterey bay - Greater farallones - .and cordell bank national marine sanctuaries - .
light to moderate winds continue over the waters from the high pressure that sits in the north, but winds will become more southerly along the big sur and Monterey bay region this evening. Otherwise, gentle breezes out of the north and northwest continue through the weekend first portion of the weekend. Dry weather continues through the forecast period as high pressure dominates.

SYNOPSIS
Issued at 108 PM PDT Thu May 9 2024
Temperatures peak today along the coast with a incoming southerly surge cooling the coastal regions on Friday. Interior regions see temperatures peak on Friday, before a slight cooldown begins over the weekend. Coastal regions cool to around the seasonal average temperatures by early next week.
SHORT TERM
(This evening through Friday)
Issued at 108 PM PDT Thu May 9 2024
The peak of the heat event has started with highs today ranging from the low to mid 70s at the coastal regions, to the low to mid 80s at the Bayshore and near Santa Cruz, to the upper 80s across the interior valleys. The interaction between a strong ridge building into British Columbia and the Pacific Northwest with a weak cut-off low in the Great Basin is creating offshore flow across the region, but this pattern is also one that will tend to create a "southerly surge" of coastally trapped winds. Indeed, the high resolution HRRR is showing a southerly surge coming up the Central Coast today, abating overnight before a second surge travels farther north across the California coast, beyond the Golden Gate and Point Arena. Those two southerly surges will bring some relief to the coastal Central Coast later today, and to the coastal regions tomorrow, with Friday's coastal highs expected to hover around the upper 60s to lower 70s. The surges will also provide the only substantial chances for cloud cover near the coastal areas impacted. That is little comfort to those inland, where high temperatures will continue to rise on Friday with the warmest spots bumping into the lower 90s.
Even the City, which does see some relief from the approaching southerly surge, is expected to top out in the upper 70s tomorrow.
The region will generally see a Minor HeatRisk today and Friday, with a Moderate HeatRisk for the interior regions of the North Bay, East Bay, and South Bay. This corresponds to a low to moderate risk of heat-related illnesses for vulnerable populations (children, the elderly, pregnant women, people without adequate cooling, and people with certain medical conditions). Here's a reminder of some heat safety tips:
* 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
(Friday night through next Wednesday)
Issued at 108 PM PDT Thu May 9 2024
As the upper level ridge weakens as it moves through the Pacific Northwest over the weekend, onshore flow will begin to reassert itself. Coastal regions will continue to cool down and reach seasonal average highs of around the upper 50s to lower 60s by the early part of next week. The interior will continue to remain warmer than seasonal averages, but not as warm as the forecast for Friday, with highs generally in the low to mid 80s by the early part of next week. Ensemble model clusters are in agreement over a new ridge expected to approach the Pacific Northwest by Tuesday, but its evolution after that point remains unclear.
AVIATION
(00Z TAFS)
Issued at 428 PM PDT Thu May 9 2024
VFR through the TAF period for most terminals, except Monterey Bay terminals. Models show the southerly flow tonight with a return of stratus near the Salinas Valley and along the coast, mostly near Monterey Bay. Low to moderate confidence that MVFR ceilings will develop tonight, but if they do, expect near 09-11Z.
Winds will start to shift overnight but will relatively light. A return of N/NW winds are expected by late Friday morning.
Vicinity of SFO...VFR through the period. Moderate northerly winds will turn westerly this evening before becoming N/NE again by early Friday morning. By Friday afternoon, winds will return to onshore and breezy.
SFO Bridge Approach...similar to SFO.
Monterey Bay Terminals...VFR through early tonight but models show MVFR ceilings returning near the terminals. Therefore, included a SCT group for KMRY and BKN group for KSNS, as there is higher confidence for KSNS experiencing MVFR CIGs .
