KEY MESSAGES

Updated at 1200 PM PDT Sun Jun 28 2026

- Seasonally cool temperatures along with breezy afternoon winds persist into the middle of the week

- Increased risk of sneaker waves and strong rip currents through Wednesday morning along the Pacific coast

- Gradual warming trend begins late week and into next week

SHORT TERM

Issued at 1200 AM PDT Tue Jun 30 2026 (Tonight through Wednesday)

Troughing continues to dominate the upper level pattern across the western U.S. and will continue through the middle to end of the work week. GOES satellite imagery shows the marine stratus continuing to push inland into coastal communities from Point Reyes southward as of 1200 AM PDT. Marine stratus will continue to fill into the area overnight clearing late this morning. Today, high temperatures will be generally within a few degrees of normal with coastal areas forecast to be in the upper 50s to low 60s, warmer for the inland communities in the mid 70s to upper 80s with some areas seeing into the lower 90s.

Long-period southerly swell will continue to increase the risk for sneaker waves and strong rip currents along the Pacific coast, particularly at south and southwest facing beaches. A Beach Hazards Statement remains in effect through Wednesday morning, see the BEACHES section for more details. Never turn your back to the ocean!

LONG TERM

Issued at 1200 AM PDT Tue Jun 30 2026 (Wednesday night through next Monday)

The aforementioned troughing will begin to flatten towards the end of the work week as ridging begins to develop in the south-central U.S., and zonal flow sets in. As the ridging builds into the weekend, high temperatures will rise across the area, but only to Minor HeatRisk levels. There is still a degree of uncertainty the center for the building high pressure and how strong the ridging will be. The Climate Prediction Center guidance shows an increased likelihood of above normal temperatures in the 8 to 14 day outlook.

AVIATION

(06Z TAFS) Issued at 817 PM PDT Mon Jun 29 2026

Moderate to high confidence in MVFR/IFR ceilings developing at bayshore and coastal terminals respectively tonight; higher confidence in CIGs coming in early morning hours around sunrise for areas near SFO and OAK. Diurnal winds will prevail. CIGs fill back in around the bay regions Tuesday night.

Vicinity of SFO...VFR with elevated winds out of the northwest through the evening. Moderate confidence on a ceiling returning near 11-13z, with MVFR more likely. Reasonable best case scenario is a donut hole develops over the terminal with stratus remaining confined on the north and west sides. Stratus not sticking around for too long, becoming VFR after 16z with elevated winds returning in the afternoon with gusts near 25 kts at times.

SFO Bridge Approach...The San Mateo Bridge Approach has low probabilities (<30%) for developing a ceiling below FL045. Reasonable best case scenario is clouds remain confined to the terminal and northward.

Vicinity of SJC and OAK...High confidence in VFR and diurnal winds prevailing at SJC. Moderate confidence in an MVFR ceiling developing at OAK tonight via a stratus feed through the Golden Gate Gap between 11-17z. VFR into Tuesday afternoon/evening with westerly winds for both sites. CIGs returning to OAK later Tuesday night with lower confidence on timing.

Monterey Bay Terminals...MVFR/IFR cigs will cover both terminals through the night. Clearing looking likely for both terminals Tuesday 16-18z, highest confidence at SNS. Lighter westerly winds tonight becoming elevated with gusts near 20 kts by Tuesday afternoon. Low to moderate confidence on cigs returning a bit earlier Tuesday evening between 03-05z.

MARINE

(Tonight through next Sunday) Issued at 817 PM PDT Mon Jun 29 2026

Strong northerly breezes will continue through Friday for the outer waters and the coastal jet region of Point Reyes. This will create hazardous conditions for small craft. Frequent gale force gusts are expected across the northern outer waters and along the Point Reyes coastal jet region through Wednesday, a bit weaker Thursday and Friday. Moderate northerly breezes will prevail elsewhere. Rough to very rough seas will continue through Wednesday before abating to become moderate to rough Thursday into Friday.

BEACHES

Issued at 236 PM PDT Mon Jun 29 2026

A Beach Hazards Statement remains in effect for Pacific Coast beaches through 5 AM Wednesday. Long period southerly swell will create an increased risk of sneaker waves and strong rip currents. This will be especially true for south and southwest facing beaches with moderate to steep slopes along the North Bay, San Francisco Peninsula, and Santa Cruz coasts. Sneaker waves can sweep across the shoreline without warning, pulling people into the sea from rocks, jetties and beaches. Dangerous swimming and surfing conditions and localized beach erosion can be expected. Stay off of jetties, piers, rocks, and other waterside infrastructure. Remain out of the water to avoid hazardous surf and NEVER turn your back on the ocean. Monitor local weather, surf and tide forecasts at www.weather.gov/mtr.
