Let’s talk about what to expect across Marin—from San Rafael to Sausalito, Mill Valley to Fairfax. We’ll also throw in some travel, hiking, and daily routine tips as you plan your weekend.
What Marin County residents can expect this weekend
Damp weather probably starts Friday night with light rain. That could hang on into Saturday morning.
This weekend, a cool air mass will push down from the north, so mornings in Marin will feel brisk and damp. Some parts of the North Bay might see skies clear up a bit by Sunday evening.
If you’re heading to weekend markets in Mill Valley or Corte Madera, bring an umbrella and maybe a light jacket. Showers should become more persistent on Sunday, especially in towns like San Anselmo and Ross.
Forecast models show the heaviest rain arriving Sunday, then easing up to showers by Monday. Coastal communities like Sausalito and Tiburon should watch for slick roads and maybe some minor ponding in low spots after the storms.
If you’re driving through Marin—into San Rafael or across the Golden Gate into Tiburon—slow down on the wet pavement. You might hit brief delays near ferry lines or downtown streets.
Local impacts by Marin towns
- San Rafael: Expect brief showers and scattered downpours. Sidewalks near the Civic Center and Canal streets could get slick and see some light ponding.
- Novato: Localized rainfall is possible. Schools and community centers should keep an eye on weather updates Sunday in case downpours get heavier.
- Mill Valley: Trails around Cascade Canyon and Mt. Tamalpais will probably be damp. If you’re hiking Sunday or strolling Monday, take it slow in the old-growth groves.
- Sausalito: Waterfront and shore roads may get some spray and slick spots. Drivers should allow extra time on Bridgeway during the worst of the rain.
- Tiburon: Inland roads could turn slick, and ferry service might be affected by gusty winds and choppy bay waters.
- Corte Madera: Shopping districts will see showers. If you’re headed to The Village on Sunday, maybe plan for something indoors.
- Larkspur: Some residential streets might see surface water. City crews will keep an eye out for minor flooding in the low-lying spots.
- San Anselmo: Light rain is likely in the historic center, but the weekend shops stay open. Pack an umbrella for a stroll along San Anselmo Avenue.
- Fairfax: It’ll feel cooler, especially north of the Mount Tamalpais foothills. Expect misty rain and damp pavement late Sunday into Monday.
Trail closures and safety reminders for Marin hikers
Rain and ice could show up at higher elevations, so Marin’s outdoor areas around Mount Tamalpais and nearby open spaces might close temporarily for safety. Local authorities urge hikers to avoid steep, slick slopes and pay attention to any posted closures.
Thinking about a weekend trip to Stinson Beach or Muir Beach? Check trail conditions before you go—especially if you’re eyeing the Marin Headlands or Point Reyes, where wind and showers can make footing tricky.
Weather patterns and the longer-range outlook
The forecast sits against a backdrop of broader climate patterns. Right now, forecasters say there’s an ENSO-neutral setup with an 80% chance it’ll hold through April–June 2026.
Looking further out, there’s a 61% shot that El Niño will arrive and stick around through the end of 2026. That could mess with late-year storm tracks and rainfall in Marin and the Bay Area.
For Marin residents, this just means rainfall will keep bouncing around week to week. Future storms could bring more moisture or show up at different times, depending on how these bigger climate patterns shift.
Stay tuned to updates from the National Weather Service and your local agencies as the storm moves in. If you’re traveling around Marin, especially on weekend roads or in the higher spots near Mt. Tamalpais and the coastal hills by Point Reyes, just take it easy.
Check your city pages for real-time advisories, and if you haven’t signed up for emergency alerts yet, now’s a good time.
Staying prepared in Marin County
In Marin, whether you’re in San Rafael, Novato, or Fairfax, preparation really matters. It’s just part of living here.
Keep an emergency kit handy at home and toss one in your car too. I’d even stash a spare umbrella in the backseat—especially if you’re braving Mill Valley’s rainy commutes.
Think ahead about some backup indoor plans, just in case Sunday’s showers ruin your outdoor fun. For storm updates, I usually check the National Weather Service, the Marin County Office of Emergency Services, or sometimes my city’s public works department.
Stay dry out there, stay safe, and honestly, try to enjoy the fresh, storm-washed beauty that rolls over Marin’s towns. There’s something special about Sausalito’s waterfront or the hills above San Anselmo after a good rain.
