You definitely get less fog in the Chapman Park area than other areas of Southern Marin, and a little more sunshine. But the most important thing is that Marin weather in general is really some of the best weather in the country. For much of the year, from April through November or so, it seems like constant sunshine. From November through March there is definitely some rain, and it can be a little colder, but not compared to the rest of the country! While the East Coast is still getting blizzards we can have warm, sunny days. We have definitely had more rain than usual this winter, but that is a healthy thing and keeps the area "green" and helps keep our redwoods alive here in Mill Valley!
