Marin County is Mediterranean Mild

Marin County is studded with microclimates that contribute to the great diversity of flora and fauna enjoyed by Marin home owners. Over its 520 square miles, Marin’s climate ranges from moist and cool to hot and dry, depending upon the season. But all of Marin enjoys what’s commonly known as a Mediterranean climate – similar to that of Italy, Greece and Spain.

Regional Differences

Along the rugged Marin coastline, sea breezes keep temperatures down and fog rolls in and wraps around coastal communities.  In the summer, home owners in this niche of Marin County may experience temperatures as much as 40 degrees cooler than do residents further inland. Consequently, when Novato home owners are basking in dry summer heat that can reach the century mark, a drive to Stinson Beach on the south coast or Dillon Beach in the north might find temperatures in the 60s.

Proximity to the ocean, and San Francisco and San Pablo bays tends to temper the summer heat, even inland, as fog drifts through Marin’s valleys and up its hillsides. Unlike much of inland Central California, Marin home owners generally get a respite from the heat of the day as the mercury falls in the evening.

There are subtle variances in microclimates throughout Marin. The inland coastal redwood and pine forests shade the ground and shelter Marin home owners in the unique environment that skirts the coastline from south to north.  The redwoods thrive in the moderate Mediterranean climate where fog provides adequate moisture level in the summer and plenty of rain in the winter. In this microclimate, swings in temperature are relative mild, pleasing both the redwoods and families at home in the wooded regions of Marin County.

In Southern Marin County, Mt. Tamalpais rises 2,600 feet and brings even greater variety to the topography and weather patterns of Marin County. The many byways and ridges that lead over the mountain to the coast, or up to its peak are studded with redwoods and oak forests. Weather on the mountain reflects the season – warm to hot in the summer and cool and damp in the winter.

From May to September, Marin home owners rarely experience precipitation. The wettest months are December through February when the county gets 90% of its annual rainfall.  Rain is an important ingredient in the continued health of Marin county forests, its numerous creeks and ecosystems.

Environmental Pioneers

Marin County home owners have long supported efforts to sustain the environmental health of the region. In 2002, the Board of Supervisors adopted a resolution expressing concern about global warming and taking responsibility for acting locally.  The effort has had a measurable impact on the quality of Marin’s environment. Local government took early steps to reduce auto and industrial emissions. Marin home owners and businesses recycle more products than any county in the state; there is an active Green Business Program, and other incentives to safeguard the local environment.

In Marin, the climate is more than weather and temperature. It is an attitude and a purposeful way of life. People owning Marin County real estate participate in being good stewards of the land and special climate they’ve inherited.
