KEY MESSAGES

Updated at 1238 PM PDT Mon Jul 6 2026

- Seasonably 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 1238 PM PDT Mon Jul 6 2026 (This evening through Tuesday night)

The marine layer was slightly deeper overnight which resulted in further inland extent into the valleys this morning. However, visible satellite imagery is showing gradual clearing back to the coast as of early this afternoon. That said, locations along the coast may very well not see the sun at all today, or maybe just brief breaks in the cloud cover. Temperatures will remain seasonably cool this afternoon.

For tonight and into Tuesday morning, expecting coastal stratus to return back into the inland valleys. Once the low clouds retreat to the coast by Tuesday afternoon, expect slightly warmer temperatures compared to previous days.

LONG TERM

Issued at 1238 PM PDT Mon Jul 6 2026 (Wednesday through next Sunday)

A gradual warming trend will begin Wednesday, yet temperatures will still be a few degrees below seasonal averages. As high pressure strengthens over the Desert Southwest and southern California, temperatures will warm to near seasonal averages and potentially slightly above. That said, only expecting Minor HeatRisk with isolated pockets of Moderate in the warmest interior spots on Thursday. All in all, a typical summer time pattern with stratus keeping conditions cooler near the coast while the interior warms up.

AVIATION

(06Z TAFS) Issued at 940 PM PDT Mon Jul 6 2026

The stratus came in a little faster than last night with ceilings a couple hundred feet lower. The TAFs have been adjusted to account for this trend, as well as delaying the clearing time for many terminals given the deeper cloud layer than expected. This is also a good set up for some coastal drizzle, and patchy fog is also possible from 12-16Z or so.

Vicinity of SFO...The clouds actually made it over the mountains rather than swirling around the Bay. This indicates a higher cloud top and overall deeper cloud layer than last night. With stronger onshore wind developing over the next 24 hours, there is actually a chance that the ceilings don't clear at all this TAF period. I still show 6 hours of VFR conditions surrounding 00Z, but the window is closing with the latest trends. Winds will remain out of the standard WNW direction, but will gust to near 30 knots in the afternoon.

SFO Bridge Approach...The approach was the last part of the Bay to fill in, but will soon be firmly ensconced in the stratus.

Monterey Bay Terminals...With the deeper marine layer, it's very unlikely MRY will clear for more than a few hours tomorrow afternoon. SNS should still get a break, however.

MARINE

(Tonight through next Sunday) Issued at 940 PM PDT Mon Jul 6 2026

NW winds will increase to a strong breeze Tuesday and persist into the weekend. Wind waves will build to rough by Wednesday, while a long period low SW swell moves through this week.

BEACHES

Issued at 1238 PM PDT Mon Jul 6 2026

A Beach Hazards Statement remains 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.
