KEY MESSAGES

Updated at 142 AM PDT Sun Mar 29 2026

- Above normal temperatures today.

- Cooler conditions return Monday, though temperatures remain above normal. - Periodic chances for light rain Tuesday-Thursday.

- High temperatures Tuesday-Thursday will be near normal to below normal.

SHORT TERM

Issued at 142 AM PDT Sun Mar 29 2026 (Today and tonight)

Quiet weather continues through Sunday, with the morning forecast including a southerly surge of stratus. This can be seen on satellite this morning as it creeps up the coast of Monterey. The question becomes how far up the coast it makes it before it gets mixed out by morning. After that, another warm day is on tap with high temperatures being above normal again.

LONG TERM

Issued at 142 AM PDT Sun Mar 29 2026 (Monday through Saturday)

Zonal flow continues through Monday, though a cooling trend will begin. High temperatures will remain above normal for one more day, before becoming near normal to just below normal on Tuesday due to a pattern change. An shortwave trough passes over the region which will bring 20-40% chance of rain, favoring the coastal mountains and the Bay Area. Wednesday chances increase for the North Bay before gradually tapering off into Thursday. Temperatures begins to rise Friday and into the weekend. An upper low slides into the PacNW Thu and then looks to slide into intermountain west, while high pressure builds over the western Pacific. This may also bring some breezier winds.

AVIATION

(12Z TAFS) Issued at 439 AM PDT Sun Mar 29 2026

VFR for all sites except MRY and SNS where stratus is attempting to fill in over the Monterey Bay. High clouds are expected to build in this afternoon and will persist through the remainder of the TAF period. Breezy onshore winds return this afternoon with winds peaking between 10 to 15 knots. Winds diminish overnight becoming variable at times. Another shallow marine layer looks possible tonight but HREF guidance keeps the stratus bank located along the Big Sur coastline.

Vicinity of SFO...VFR. Onshore winds strengthen by early this afternoon with winds peaking around 15 knots. Winds weaken overnight before strengthening again late tomorrow morning into the afternoon.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Currently VFR with the potential for IFR CIGs to return this morning. Confidence is mixed as to if stratus will fill in over the Monterey Bay and reach SNS/MRY. Recent high resolution guidance suggests stratus will stay out of the Monterey Bay while other models suggest it will fill in. Kept tempos in for IFR CIGs at MRY and SNS from 12Z to 16Z but confidence is low. Otherwise, onshore winds increase this afternoon with winds peaking between 10 to 14 knots. Another shallow marine layer is likely to develop tonight but confidence is mixed as to if it will make it to MRY/SNS. For now, leaning towards stratus not reaching MRY/SNS tonight but if it does it is likely to occur late (after 12Z Monday).

MARINE

(Today through Friday) Issued at 439 AM PDT Sun Mar 29 2026

Moderate to fresh northerly winds continue across the outer waters with locally strong gusts across the far northern outer waters. Occasional fresh to strong gusts continue across the northern waters through early Monday before winds diminish. Light rain is possible Tuesday through Thursday. Hazardous conditions for small crafts return mid to late week as significant wave heights build and winds increase to near gale force.
