About Our Weather!
Here in Marin we only have three seasons—good, better and the best! It is mild here year round, so you can enjoy the great outdoors any time in comfort. In general, we have beautiful weather from April through October. In October, November, and December, we may have light rains and lower temperatures (but rarely close to freezing). Even on the coldest days, the afternoons can be sunny and warm. The heaviest rains are usually in January and February. But while we are having our “winter,” narcissus are blooming, and by mid-February springtime is in full bloom.
During the summer in San Francisco and some parts of Marin the fog rolls in from the ocean—usually morning and late afternoon. Because of the protection by Mount Tamalpais, most of Marin is free of the fog. However, the fog brings cool nights, perfect for sleeping after warm days.
Fall is a special time in Marin. It is better than Indian summer—it’s more like a second springtime. The fog is gone and there are many spectacular beach days in southern Marin and West Marin. Gardens come back into heavy bloom and roses keep going till late in the year.
If this inspires you to move to Marin, contact us and ask to receive our Free Marin County Relocation Package. It’s packed full of useful and important information. Don’t move here without it!
