Synopsis for the central california coast and bays including the Monterey bay - Greater farallones - .and cordell bank national marine sanctuaries - .
widespread stratus continues across the coastal waters into tomorrow morning. Fair weather and moderate northwesterly winds with the occasional fresh gust continue through the end of the weekend. Gustier conditions will develop across the northern outer waters and along the big sur coast beginning Sunday afternoon. Northwest winds increase to a fresh breeze across all of the coastal waters starting Monday as surface high pressure over the eastern pacific ocean builds and moves east. As winds strengthen, significant wave heights will build through the early work week reaching heights of 12-15 feet by mid-week before beginning to diminish Thursday.

New SYNOPSIS, SHORT TERM, LONG TERM
SYNOPSIS
Issued at 1228 AM PDT Sun May 12 2024
A relatively quiet pattern will develop featuring overnight and morning coastal clouds with clear skies elsewhere. Inland temperatures will warm into the 70s and 80s each afternoon with cool onshore breezes keeping coastal temperatures in the 60s.
SHORT TERM
(Today and tonight)
Issued at 1228 AM PDT Sun May 12 2024
The marine layer has deepened appreciably with an inversion height around 800 to 1200 feet per area profilers. Low stratus is widespread early this morning with greater inland penetration as compared to yesterday. For those hoping to view the Aurora your best bet is to either head inland or into the higher terrain above the marine inversion. Given the deeper marine layer we're seeing much less in the way of fog as compared to yesterday as cloud bases are generally just a tad above the surface. The large-scale picture features weak troughing aloft over the West Coast with downstream ridging over the Desert Southwest region. This pattern will support the continued deepening of the marine layer with a repeat performance of low stratus tonight. For today, expect clouds to gradually clear towards the coast with inland warming. High temperatures will range from the 60s along the coast, to the 70s for the marine influenced valleys, to the 80s for the warmest inland locations. A few hot spots across southern Monterey County may even eclipse the 90 degree mark. Temperatures tonight will be mostly in the upper 40s to lower 50s, with readings a bit warmer in the higher terrain inland.
LONG TERM
(Monday through Saturday)
Issued at 1228 AM PDT Sun May 12 2024
Temperatures will cool slightly with onshore flow and weak troughing aloft persisting. An upper ridge does build/strengthen over the northeast Pacific by mid week, but it appears our area will remain along its periphery with no strong signal for a warming trend. In general high temperatures will range from the 60s along the coast to the lower-mid 80s for the warmest inland areas. This will only produce a minor HeatRisk for the warmest locations. Lows will generally be in the lower to mid 50s. Coastal clouds are likely during the overnight and AM hours with a gradual clearing towards the coast each afternoon.
AVIATION
(06Z TAFS)
Issued at 1035 PM PDT Sat May 11 2024
Currently seeing a mix of VFR-IFR at the terminals as a deeper marine layer of about 1,000 feet is being allowed to protrude further inland. With the exception of LVK, all terminals will experience a reduction in flight category within the TAF period.
Widespread VFR and breezy onshore flow will prevail by tomorrow afternoon.
Vicinity of SFO...Currently VFR with breezy northwesterly flow.
Low-end MVFR conditions will return to the terminal overnight with clearing expected by 18Z. Winds will remain breezy out of the west/northwest through the TAF period. MVFR conditions look to make a return again tomorrow night.
SFO Bridge Approach...Similar to SFO.
Monterey Bay Terminals...Currently LIFR with northwesterly flow at both terminals. Both terminals will improve to VFR by the afternoon.
Winds will remain breezy out of the west/northwest through the TAF period. LIFR/IFR conditions are slated to return to MRY and SNS respectively again tomorrow night.

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...None.
PZ...Small Craft Advisory from 3 PM this afternoon to 3 AM PDT Monday for Pt Pinos to Pt Piedras Blancas 0-10 nm.
Small Craft Advisory from 3 PM this afternoon to 9 PM PDT Monday for Pt Arena to Pt Reyes 10-60 NM.
