KEY MESSAGES

Updated at 1203 AM PDT Mon Jul 6 2026

- Seasonally cool temperatures through Tuesday before a warming trend arrives for the second half of the week

- Marine layer stratus develops each evening and overnight before retreating to the coast each morning and afternoon

- Long period southwest swell causes an increased risk of sneaker waves and strong rip currents Tuesday through Friday

SHORT TERM

Issued at 1203 AM PDT Mon Jul 6 2026 (Today and tonight)

The marine layer clouds have come in pretty far inland, coming into the Sonoma County valleys, across the SF Bay Area and into the hills surrounding Livermore, and down the Salinas Valley. Expect extensive stratus development through the rest of the night, as the marine layer sits around 2000 feet deep, followed by gradual inland clearing through the morning and early afternoon while the coastal areas remain socked in.

Zoom out to the larger scale and you'll find troughing to the west over the Eastern Pacific, ridging to the east over the Intermountain West, and we're stuck in the middle with them. Temperatures remain below the seasonal averages as the marine layer remains in place and breezy onshore winds develop in the afternoon and evening. High temperatures today range from the middle 70s to the middle 80s in the inland valleys, up to the middle 90s in the warmest interior spots particularly in southern Monterey County, the middle 60s to the middle 70s close to the Bays, and the middle 50s to lower 60s along the Pacific coast. Wind gusts this afternoon reach 20 to 25 mph through favored gaps, passes, and the northern Salinas Valley.

LONG TERM

Issued at 1203 AM PDT Mon Jul 6 2026 (Tuesday through Sunday)

Tuesday should feature broadly similar conditions to today, with a stronger afternoon breeze possible as the ridge gradually retrogrades and the pressure gradient tightens. Towards the middle and later parts of the week, temperatures will gradually rise inland as the ridge strengthens and moves into the Desert Southwest, with a particular emphasis on Wednesday through Friday when local temperature gradients range from the lower to middle 60s at the immediate coast to the upper 80s to lower 90s in the inland valleys, to the triple digits up to 105 within the warmest spots of southern Monterey County. Afterwards, ensemble model cluster analysis continues to support the ridge axis paring back to the Intermountain West for the upcoming weekend, which would support some subtle cooling, although temperatures will remain near to slightly above the seasonal average.

As a final note, long period southwest swell will result in hazardous beach conditions Tuesday through Friday; see the BEACHES section for more information.

AVIATION

(12Z TAFS) Issued at 423 AM PDT Mon Jul 6 2026

Primarily MVFR ceilings with KHAF and KSTS hovering between IFR/LIFR with a robust marine layer in place. VFR conditions are expected by early afternoon for all terminals with the exception of KMRY, which may remain MVFR/IFR through the forecast period.

Vicinity of SFO...Light winds this morning will become breezy and remaining onshore. Moderate confidence of VFR ceilings by mid/late morning with MVFR ceilings returning by early evening and persisting through or close to the remainder of the TAF period.

SFO Bridge Approach...Similar as SFO.

Monterey Bay Terminals...Moderate confidence that KMRY will remain MVFR/IFR through the forecast period, with the potential for LIFR around sunrise into mid-morning. VFR is expected at KSNS by early afternoon with MVFR ceilings filling back in by early evening and continuing through the remainder of the forecast period.

MARINE

(Today through Saturday) Issued at 423 AM PDT Mon Jul 6 2026

Moderate northwest winds and seas will persist today. Strong northwest winds will develop Tuesday and are expected to prevail through the remainder of the week into the weekend. Along with the strong winds expect building rough waves mixed with a low southwest swell.

BEACHES

Issued at 931 PM PDT Sun Jul 5 2026

A Beach Hazards Statement is in effect for Pacific coast beaches from Tuesday morning through Friday afternoon. Long period southwesterly swell will create an increased risk of sneaker waves and strong rip currents, as well as breaking waves up to 10 feet. 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.
