KEY MESSAGES

Updated at 1254 PM PDT Sat Jul 25 2026

- Breezy onshore winds expected each afternoon and evening through early in the week

- Temperatures near seasonal averages through the first half of the week

- Gradual warming by the end of the week with increasing Moderate HeatRisk potential across the interior

SHORT TERM

Issued at 1254 PM PDT Sat Jul 25 2026 (This evening through Sunday night)

With mostly sunny sky conditions across the region this afternoon, temperatures will be seasonably warm. The warmest will be across the interior with 80s to lower 90s and mid-to-upper 90s across the warmest portions of the far interior valleys. Stratus is once again forecast to make a return to the coast late tonight and into the coastal adjacent valleys by Sunday morning. However, a very similar weather pattern is forecast as this morning, so confidence is low to moderate at best. The marine layer is forecast to remain around 1,000 feet in depth, so we'll see how tonight pans out. For Sunday, expecting similar conditions as today.

A long-period (20-22 second) southerly swell has arrived along the San Francisco Bay Area and Central Coast! Be advised, sunny conditions along the coast will make for an increase in visitors (tourist, out of state, and even locals trying to escape the inland heat). The Beach Hazards Statement has been extended into Wednesday afternoon as tropical cyclone Genevieve in the Eastern Pacific will also impact conditions along our coastline. For more on this, please see the Beaches section of the AFD below.

LONG TERM

Issued at 1254 PM PDT Sat Jul 25 2026 (Monday through next Friday)

Not much change in the extended forecast. Expecting near normal temperatures to persist into the first half of the week as high pressure remains over the Four Corners region and troughing persists off of the Pacific Northwest coast. A gradual warming trend, especially across the interior, is expected as the high pressure builds toward and over southern California late this week into next weekend. However, onshore winds are forecast to persist through this period allowing for cooler conditions near the coast. By Thursday and into next weekend, we see more widespread Moderate HeatRisk across the interior.

AVIATION

(18Z TAFS) Issued at 1117 AM PDT Sat Jul 25 2026

It is a beautiful day across our region with widespread VFR conditions persisting into the evening. Winds remain moderate through the day and diminish to gentle breezes overnight. North Bay terminals will experience S-SW winds and terminals south of the Golden Gate will generally be W-NW. A compressed and dry marine layer with a depth of roughly 1000 feet returns overnight after ~08Z Saturday. It may be too compressed to fill in over SJC and LVK. Low confidence on whether STS will experience foggy conditions overnight. There is sufficient dry air at the surface that may inhibit fog formation even with a compressed marine layer, light winds, and clear skies overhead.

Vicinity of SFO...Clear skies and fresh westerly breezes with 30 kt gusts prevail into the evening. MVFR ceilings develop over the terminal around 10Z Saturday through 17-18Z. Medium confidence on the exact timing, though 09-10Z is fairly consistent with the trend we've seen the past couple of nights.

SFO Bridge Approach...Similar to SFO. May develop MVFR ceilings before and scatter out after SFO.

Monterey Bay Terminals...Moderate onshore winds persist through the day. IFR ceilings arrive at MRY first before filling in over SNS. High confidence on the estimated arrival of stratus, medium confidence on when it will scatter out of the terminals.

MARINE

(Today through Thursday) Issued at 911 AM PDT Sat Jul 25 2026

A long period southerly swell is impacting our coastal waters from distant tropical cyclone activity in the Eastern Pacific. These conditions will persist through the middle of next week. Fresh NW breezes with embedded gale force gusts prevail through the weekend. NW breezes increase to strong by the middle of next week as moderate seas build to rough in response.

BEACHES

Issued at 911 AM PDT Sat Jul 25 2026

Tropical cyclones in the Eastern Pacific are generating a long- period southwesterly swell which has reached the coastline of the San Francisco Bay Area and Central Coast. As such, sneaker waves and strong rip currents are the primary concerns. However, breaking waves can reach up to 10 feet along some south and southwest facing beaches and break points (like Santa Cruz, Pacifica, and parts of Stinson or Ocean Beach). Sneaker waves can have 20+ minutes in between the larger sets (breaking waves) with significant "flat/calm looking" times between them. This can potentially catch beachgoers by surprise and resulting in people being swept into the cold turbulent ocean; hence the name "sneaker". Rip currents are strong enough to pull the strongest swimmers away from shore. Swim near a lifeguard if possible. Stay back from the beach, and away from jetties, piers, beachside rocks, and other infrastructure near the water. Never turn your back to the ocean! The Beach Hazards Statement has been extended through Wednesday afternoon for all beaches along the Pacific Coast.
