Marin Weather Outlook This Week
The system looks weak, but it’s worth keeping an eye on—especially for coastal hills and low-lying valleys from Corte Madera to Ross and beyond.
In towns like San Anselmo, Mill Valley, and Larkspur, a few showers could roll through, especially on Wednesday night. Skies will stay variable on Tuesday, with some clouds and sun breaks.
Showers might show up late Wednesday into Thursday morning, mostly in the higher terrain.
Rain, Winds and Timing
Forecasts put a 20% to 30% chance on measurable rain in parts of Marin during Wednesday night. If rain does fall, it’ll probably stay under a quarter inch, and most places will stay dry.
Light, scattered shower activity should mostly hit the coastal hills around Sausalito, Tiburon, and Fairfax. Showers could move in and out of the San Anselmo and San Rafael corridors.
Winds will ramp up late Wednesday into Thursday, especially on ridges and exposed coastal spots.
Look out for gusts of 25–35 mph in the hills near Fairfax, Corte Madera, and the Drake’s Bay wind corridors. Along the Marin Coast, drivers might notice a breezy stretch, especially in the hills.
- Timing: Tuesday should be partly cloudy and milder. Temperatures will hover in the upper 60s to low 70s across the North Bay—think San Rafael, Novato, and San Anselmo.
- Rain chances: The odds of measurable rain go up Wednesday night, then fade Thursday as the system heads toward the East Bay.
- Rain totals: Most neighborhoods will get under a quarter inch, with just a few spots seeing a bit more—enough to slick up sidewalks in downtown Marin, but not enough to flood streets.
- Locations of note: Mill Valley, Sausalito, Larkspur, Tiburon, Corte Madera, and Greenbrae should stay alert for quick downpours and slick roads after dusk on Wednesday.
If you’re in San Rafael or Novato, keep an eye on the radar and watch for spotty showers in the North Bay valleys.
Those in Fairfax and San Anselmo could see wind-driven gusts along the hillsides, with a few slick spots on local roads where leaves and moisture meet pavement.
Climate Context and Bay Area Water Outlook
Marin’s rain cycle fits into a bigger Bay Area pattern shaped by climate swings. This week’s system might bring a little moisture, but the real story is the ongoing drought and the way it shapes water decisions in Marin and the rest of the Bay Area.
Even with a few showers, those persistent dry spells and a shrinking Sierra Nevada snowpack keep reminding us that every drop matters for water supplies and forest health.
Drought, Snowpack, and Local Resilience
Here in the North Bay, the drought conversation ties into wildfire risk and reservoir levels. A light midweek rain can give soil and foothill vegetation a brief break, but Bay Area water managers still push for careful use and conservation.
In Marin, communities from Ross to Kentfield rely on smart water planning, especially in dry years, and even small rains help recharge hillsides and groundwater.
For folks in Novato, San Rafael, and Sausalito, it’s worth staying tuned to radar updates, wind advisories, and road conditions. The next system might be fickle, but it’s another reminder that California’s climate keeps shifting.
Local vigilance—whether you’re driving through the Marin Headlands or hiking above Mount Tamalpais—still matters.
