If you don’t like living in the fog, these pictures demonstrate is an excellent reason to drive just a couple more exits north on the 101 freeway. As you can see, the fog sits on the mountains between Mill Valley and Corte Madera/Larkspur. While Mill Valley, Tiburon, Belvedere, Sausalito and San Francisco are socked in with fog, often the rest of Marin is sunny (and frequently 5-10 degrees warmer).
Unfamiliar with Marin? It is important to understand the many weather micro-climates of the communities. A few miles (even within the same city) can mean a substantial difference in fog, light, wind, sunshine, and even rain.
