by SACRAMENTO, CALIFORNIA — A calm golden sunrise blanketed the Central Valley this week, mist pooling low over the fields as Northern California eased into another serene morning. But while the end of October feels steady and warm, early November is hinting at change on the horizon.
Meteorologists say the pleasant fall weather won’t last forever. High pressure remains dominant across Northern California, keeping skies mostly clear and daytime temperatures hovering in the upper 70s. It’s the kind of stretch locals appreciate before the rains and chill of winter settle in.
Warm, Dry, and Perfect for Halloween Plans
For much of the Sacramento Valley and foothills, the weather through the weekend looks ideal for Halloween events, pumpkin patch visits, or late-season yard work. Friday and Saturday are expected to feature highs around 76–78°F, with light breezes and plenty of sunshine. Mornings will start off cool — near 50°F — before warming comfortably by afternoon.
“This is about as nice as it gets for the last weekend of October,” said local forecaster Daniel Swain. “Dry air, mild temperatures, and calm winds — it’s classic fall weather for the valley.”
Coastal areas, including Mendocino and Humboldt counties, will remain mild as well, with partly cloudy skies and highs in the upper 60s. In contrast, the Sierra foothills and Tahoe Basin could experience crisp nighttime lows dipping into the upper 30s, though conditions will stay dry.
High Pressure Keeping Storms at Bay
The quiet weather pattern is being held in place by a ridge of high pressure over the Pacific, which has effectively blocked incoming storm systems. The setup has created warm, stable conditions from Sacramento to Redding and across much of the North State.
However, this ridge won’t stick around forever. Computer models suggest a transition toward wetter and cooler weather starting around midweek, particularly for northern zones like Siskiyou and Shasta counties. Early indications point to light showers as Pacific moisture begins to re-enter the region by Wednesday or Thursday.

Rain Possible in Early November
By the first week of November, a weak cold front could bring the season’s first significant rainfall north of Redding, with potential spillover into the Sacramento Valley later in the week. While exact timing remains uncertain, meteorologists are tracking signs that the storm door may open wider as the month progresses.
“November looks like when we’ll finally start to see the return of Pacific storm systems,” said Swain. “We’re watching for possible snow in the Sierra between November 8–15, which could mark the region’s first true winter pattern.”
Tips for Residents During the Calm Stretch
Local officials encourage residents to take advantage of this dry window to prepare for the shift. That means cleaning gutters, checking roof drainage, trimming trees, and securing outdoor furniture before winds and rain return. Travelers using Interstate 80 or Highway 50 should also stay alert for changing weather after next week as mountain snow potential grows.
Agricultural workers and gardeners can benefit from the mild conditions as well. Soil moisture levels remain steady, and daytime warmth continues to support harvest activities across parts of the Central Valley.
Looking Ahead: From Tranquility to Transition
As of now, Northern California sits comfortably in its late-autumn sweet spot — golden light, crisp mornings, and peaceful afternoons that belie the approaching storm season. But the signals are clear: November will likely usher in cooler air, periodic rain, and even Sierra snow, reminding residents that winter is never far behind
