No rain threats are on the horizon. That’s a relief for anyone planning outdoor activities around San Anselmo, Fairfax, Mill Valley, and the rest.
Warming trend takes hold inland across Marin
As the week kicks off, inland pockets of Marin—think San Rafael, Novato, and the hills near Fairfax—are set to soak up the warmth. Highs will reach the mid- to upper-80s away from the coast, where cooler marine air keeps shoreline communities more comfortable.
Coastal towns like Sausalito, Mill Valley, Tiburon, and Belvedere will stay noticeably milder, with daytime highs mostly in the 60s to low 70s. The warmth really ramps up in Marin’s inland valleys, while the coastline stays a good spot to escape the heat.
This pattern at the start of the week favors the interior. It’s not a countywide heatwave—just that classic coastal-inland divide.
Microclimates around San Geronimo, Point Reyes Station, and Tomales are pretty different from those near San Rafael and Novato. Inland hikers in the Mount Tamalpais watershed can expect plenty of sun, while coastal walkers along the Sausalito shoreline get that gentler breeze.
Temperatures by community: who feels the heat
Here’s a quick look at what different Marin communities can expect, weather-wise. Inland cities will see the warmest readings, while coastal spots stay cooler and honestly, a bit more comfortable.
- San Rafael: mid-80s to around 88°F during peak afternoon hours
- Novato: similar range, generally mid- to upper-80s
- San Anselmo and Fairfax: low 80s to mid-80s inland, with cooler nights
- Corte Madera and Larkspur: upper 70s to low 80s, helped by a coastal breeze
- Sausalito, Mill Valley, Tiburon: coastal communities hovering in the 60s to low 70s
Midweek cooldown taking shape
Forecast models show a pattern shift by midweek, bringing a noticeable cooldown from those inland highs. Around Wednesday and Thursday, marine air will nudge inland and lead to more comfortable afternoons in places like San Rafael and Novato.
The coastline will keep its milder, breezy character. Towns like Sausalito and Tiburon can expect that persistent, pleasant maritime influence.
What this means for Marin neighborhoods
Here’s a neighborhood-focused look at the midweek cooldown. It highlights how the same air mass will feel across Marin’s wildly varied geography—from Point Reyes Station to San Geronimo:
- Sausalito: highs ease into the upper 60s to low 70s by midweek; mornings stay cool
- Tiburon: similar trend, maybe a touch warmer in the afternoons, around the low 70s
- Mill Valley: daytime temps drop to the low-to-mid 70s
- Corte Madera and Larkspur: mid-70s with a refreshing coastal breeze
- San Rafael and Novato: inland readings dip to the low- to mid-70s
- San Anselmo and Fairfax: upper 60s to mid-70s, and nights stay on the cool side
- Ross and Point Reyes Station: nights in the 40s to 50s; days near the 70s
Practical tips for a comfortable Marin week
With inland heat fading into a more temperate pattern, residents across Marin—from Marinwood to Point Reyes Station—can plan ahead. Here are a few practical tips to stay comfortable as the week rolls on:
- Drink plenty of water, especially if you’re out walking in San Rafael or Novato or hiking around Mount Tamalpais
- Don’t forget sunscreen and a hat for afternoons in Tiburon and Sausalito
- Layer up for cool mornings and evenings in Fairfax and Larkspur
- Take advantage of cooler coastal air for outdoor workouts in Mill Valley and Corte Madera
- Keep an eye on pets during the inland heat and never leave them in parked cars in San Geronimo or San Anselmo
Forecast caveats and updates
This is really just a short-term outlook. Forecasters plan to keep an eye on any changes in the marine layer or shifts in offshore winds.
The midweek cooldown should stick around. There’s no real sign of rain coming to Marin County anytime soon.
