Hiking Big RockGood weather is one of Marin County’s nicest features. The people that live here enjoy a temperate climate for most of the year, while still having the pleasure of the seasons. We rarely have extremes like snow or super hot days. In fact, when those happen, they are headline events in the local papers. However, that’s not to say that we have boring weather. In fact, our weather can be challenging as well as fun.


No matter how clearly they are explained, our micro-climates are not easily understood. Because of our beautiful location just north of San Francisco and sandwiched in between the Pacific Ocean and the San Francisco/Richardson Bays, we have a delightful combination of Marine influence and warm valleys. Over a relatively short distance, one can go from a foggy, chilly, sweater environment to a hot, tee shirt, “let’s go swimming” one. There are even smaller climate pockets, like the “banana belt” of Sausalito where there is a significant change within a matter of blocks. Experienced locals learn to keep a sweater and an umbrella in the car for traveling between towns only a few miles apart.

The marine influence creates wonderful banks of fog that flow in and out of the Golden Gate and over the westerly hills. This gives us our “natural air-conditioning”. IndeedFog over the Headlands many homes in the County do not have the other kind. This fog is also what gives us our outstanding Redwood Trees. Redwoods pull most of their water from the air and not their shallow root system. A rule of thumb is that the closer you are to water, the more the fog will affect you.

Further inland and north there is less fog, but those areas are still influenced by the lovely evening cooling that it brings. This daily flow of fog is strongest in the summer months and can create strong winds in some corridors. The upside is that these crosswinds also keep the air fresh and Marin County has very little smog. In the inland and northerly valleys, it can be very warm and swimming pools are not uncommon.



We are lucky that from approximately May through November our weather is gentle enough for residents and visitors to enjoy many outdoor activities. Sailing, biking, hiking, camping, surfing, fishing, bird watching are just the start of the list that makes Marin County an outdoor Mecca. During these months there is typically no, or very little, rain. In our warmer areas, day time temperatures can pass 100°, but typically are in the 80’s. Evenings, depending on your location and the density of fog can dip into the low 60’s.

Our winter is short and starts when it rains. We get the majority of our water during this period and most of us enjoy it. The Marin Municipal Water system is fed from a series of local alpine lakes that are filled during this time, giving us terrific, fresh water. Our micro-climates create differences in rainfall from town to town as well. Adjacent towns may see greatly different amounts of rain, but the average for the County is about 40 inches. During this time, our temperatures can dip into the low 40’s at night and even hit freezing in some areas. Daytime temperatures vary from town to town but can be from the high 40’s to the high 60’s.

What does this mean to a homebuyer? It’s important to know what you’re looking for. For us, one of the first questions we ask is “What kind of climate would you like to live in?” Take that seriously. Take a moment to understand the micro-climates that will greatly affect your day to day life. And then…Enjoy Yourself!
