Today's Weather — Lower Russian River

Tue, Oct 27, 2026 · 5:57 AM PT — Cody's morning report · Source: NWS Area Forecast Discussion

Morning, neighbors — hope your coffee's warm, because we're staying on the cool side all week here in the Lower Russian River and across Sonoma County.

Today starts with some patchy morning stratus and a little fog in the North Bay, clearing by late morning into early afternoon. Highs will be in the middle to upper 60s for interior valleys, lower to middle 60s near the bays, and upper 50s to lower 60s along the coast. Gentle to moderate onshore winds pick up this afternoon, with gusts 20 to 30 mph along the coast, through gaps and passes, and up on the ridgelines.

Heads up on the coast: minor coastal flooding is possible at high tide through the week from high astronomical tides. A Coastal Flood Advisory is in effect until 5 PM Friday for our coastal zones. Nothing major, but low spots along the shore and Bayshore can see some extra water at high tide.

Looking ahead, troughing keeps us cool through the work week, with highs dipping a bit more later in the week into the middle 50s to middle 60s. Rain chances were in the picture for late week into the Halloween weekend, but confidence has dropped — especially for the Bay Area and North Bay, where chances are now just 10-30% and measurable rain has mostly vanished from the forecast. The trend is leaning drier, with the bulk of any rain staying farther south.

Bottom line: cool, breezy, and mostly dry for Guerneville and Santa Rosa through Halloween. Grab a jacket for those afternoon winds, watch low coastal spots at high tide, and enjoy the fall feel. 🤙
