Marine Weather and Tide Forecast for Montalvin Manor, CA

UPDATE
Issued at 955 AM PDT Tue Jun 17 2025

If you were up early this morning you saw the sunrise with no clouds. We had a little bit of a break from the June Gloom this morning as marine layer stratus pretty much eroded. There was one exception, there was a patch of low clouds swirling around Monterey Bay near Moss Landing. Latest satellite imagery does show this patch of low clouds is slowly thinning. Subtle cooling aloft likely contributed to less clouds this morning - simply put weakened the marine layer inversion.

No update needed this morning. Aside from some afternoon breezy onshore flow today will feature chamber of commerce weather - sunny skies and milder temperatures.

If you're a fan of the marine layer and like the June Gloom have no fear, it's lurking off the coast. Satellite imagery shows it's about 60 miles off the coast and it's forecast to move back inland tonight.

SHORT TERM
(Today and tonight)
Issued at 305 AM PDT Tue Jun 17 2025

Temperatures warm to slightly above normal today and tomorrow with progressive upper level shortwave ridging across our area today. Very dry air above the marine layer remains in place helping to limit low stratus over our coastal areas, with bright sunshine inland. As the upper ridging shifts east, zonal flow sets up across our area late tonight when the marine layer deepens with more widespread coastal low marine layer stratus expected to return overnight into early Wednesday morning.

LONG TERM
(Wednesday through Monday)
Issued at 305 AM PDT Tue Jun 17 2025

Primarily zonal upper flow across our area on Wednesday will result in the warmest day of the week before a deepening trough leads to height falls, cooler temperatures and a more robust marine layer intruding farther inland for Thursday and beyond. Temperatures will cool back down to seasonal averages or slightly below. The upper low over the Pacific Northwest will gradually shift inland on Friday into the weekend. Gusty onshore flow for the end of the week and weekend will lead to winds up to 40 MPH at times for higher elevations, passes and gaps on Saturday, easing Saturday night.

AVIATION
(12Z TAFS)
Issued at 442 AM PDT Tue Jun 17 2025

Widespread VFR continues across the CWA Night Fog shows a small patch of clouds in the northern Monterey Bay but confidence is low that it will impact MRY and SNS this morning. VFR conditions persist through much of the day before CIGs start to build in again late this evening into the overnight hours. Highest confidence in IFR CIGs at HAF, MRY, and SNS with moderate confidence in IFR CIGs reaching OAK tonight. Guidance does show some potential for MVFR conditions to reach SFO after 09Z but confidence remains low in this scenario. Winds remain onshore (southwest to northwest) through the forecast period with breezy winds during the afternoon/evening easing and becoming light/variable overnight.

Vicinity of SFO...VFR through the TAF period. Not anticipating stratus to develop this morning but some potential exists for stratus to develop tonight. LAMP guidance indicates stratus potential increases from 09Z to 17Z with any CIGs that do develop likely to be MVFR. For now, leaned more towards high resolution guidance offered by the HRRR which suggests stratus will fill in through the Golden Gate Gap and over OAK but not reach SFO. Gusts are expected to peak around 33 knots during the afternoon/evening at SFO today before winds ease overnight into tomorrow.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...VFR becoming IFR tonight into tomorrow morning. Highest confidence in IFR CIGs moving in between 06Z-08Z tonight with stratus reaching MRY first then SNS second. CIGs are likely to persist through mid to late morning before clearing tomorrow afternoon. Moderate west to northwest winds are expected this afternoon and evening before winds ease and shift slightly southwesterly overnight.

MARINE
(Tonight through next Sunday)
Issued at 1028 PM PDT Mon Jun 16 2025

Gale force gusts will occur near the coastal jet regions of Point Reyes and Point Sur in the afternoons and look to linger into the evenings for much of the forecast.
