Today's Weather
Sat, Oct 31, 2026 · 5:57 AM PT — Cody's morning report · Source: NWS Area Forecast Discussion
Hey folks,
Good news for Halloween plans around Guerneville and the Lower Russian River — the forecast has trended drier for today.
Sonoma County and the North Bay start dry and stay dry well into Saturday afternoon and early evening. A weak front moves in later, so light rain chances increase over the North Bay Saturday night into Sunday, spreading southward as it goes. A few showers may linger early Sunday, then Sunday afternoon looks much drier. This is light rain, not a big storm.
Temperatures stay seasonal to slightly cool through the weekend, with highs mainly in the 60s.
One heads-up to take seriously: a Coastal Flood Advisory is in effect for minor to moderate coastal flooding at high tide for Bayshore and Pacific Coast locations through the weekend — through this evening for parts of the Pacific Coast, and through 6 PM Sunday for bayshore locations. Low spots near the water could see flooding around high tide.
Looking ahead, Sunday night into Monday turns dry and a little warmer. Rain chances return Monday night into Tuesday and linger into Wednesday — again, nothing big or notable. Dry, warmer weather returns Friday into next weekend.
Bottom line: enjoy outdoor Halloween plans this afternoon and evening, have an umbrella handy late tonight, and watch for high-tide flooding if you're near the coast.

Coastal Flood Advisory issued October 31 at 4:45AM PDT until November 1 at 6:00PM PST by NWS San Francisco CA
Sat, Oct 31 · 4:45 AM – Sun, Nov 1 · 6:00 PM PT
* WHAT...Up to 1.5 ft of inundation above ground level is possible in low-lying areas near shorelines and tidal waterways.
What: Up to 1.5 ft of inundation above ground level is possible in low-lying areas near shorelines and tidal waterways.
Where: Bayshore locations along the San Francisco Bay, San Pablo Bay, and Monterey Bay.
When: Until 6 PM PDT Sunday.
Impacts: High tides will result in flooding of low-lying infrastructure, isolated road closures, and coastal erosion. Rising tides will bring water and waves farther up the beach than normal, restricting escape from beaches and coastal areas. More substantial impacts are expected along bayshore Marin County where increased flooding is anticipated across low lying areas.
Additional Details: At the San Francisco tidal gauge, high tide is expected to be 1.5 feet above normal (7.3 ft MLLW) at 03:44 PM on Saturday 10/31 and 1.0 ft above normal (6.8 ft MLLW) on Sunday 11/01 at 3:59 PM. These predictions include up to 1.5 ft of surge that will enhance the astronomical tide and flooding threat. High tide varies up to 90 minutes earlier or later along the Pacific Coast and through the San Francisco Bay, respectively.
If travel is required, allow extra time as some roads may be closed. Do not drive around barricades or through water of unknown depth. Take the necessary actions to protect flood-prone property.
