Marine Weather and Tide Forecast for El Granada, CA

SHORT TERM
(This evening through Tuesday)
Issued at 214 PM PDT Mon Jun 16 2025

A weak upper level trough continues to track across the PacNW and northern CA today, with upper level ridging beginning to build in for Tuesday. This will be the start of a brief warming trend putting us closer to our seasonal highs for Tuesday. The forecast challenge for this period will be trying to figure out the depth of the marine layer and the expansion of the stratus. Guidance has it varying between 1000-1700ft for the period, with the best chances for stratus redeveloping along the San Mateo and Central Coast.

LONG TERM
(Tuesday night through next Sunday)
Issued at 214 PM PDT Mon Jun 16 2025

Upper level ridging holds through Wednesday with the next hint of height falls occuring late Wednesday into Thursday. An upper level low is slated to slide down the western Canadian cost and enter the PacNW for the weekend. This will lead to a period of troughiness and temperatures falling to near normal or just below normal. Expect the summer time stratus to return, with the fine tuning of its arrival occuring as we get closer to the later portion of the work week and weekend.

AVIATION
(18Z TAFS)
Issued at 1028 AM PDT Mon Jun 16 2025

Coastal stratus eroding nicely across the region this morning and should be clearing to VFR for the rest of the day. Exceptions may be isolated coastal terminals such as HAF, which may end up with a mixed bag today. Expecting most terminals to remain VFR through tonight as dry air sufficient enough to mix out the clouds intrudes into the marine layer. Gusty NW winds this afternoon as a shortwave trough starts to move through the region.

Vicinity of SFO...Once stratus clears this morning, VFR is anticipated for the rest of the period. Gusty NW winds this afternoon through the San Bruno gap, potentially in excess of 30 kts and up to 35 kts. Winds diminish overnight.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...A bit slower clearing down along the Monterey Bay this morning, but still expecting a VFR afternoon.
Breezy diurnal onshore flow and a marginal return of stratus expected tonight. Low confidence on if tonight's stratus will be enough coverage to constitute a CIG or not.
