Point Reyes Peninsula's climate is characterized by warm, dry summers and cool, rainy winters, similar to the type of climate that prevails on the Mediterranean. Usually, there are constant winds of moderate to strong velocity on the exposed headlands and outer beaches. Headlands and beaches on the Pacific Coast are subjected to frequent heavy fogs. Such heavy fogs are most common in the months of July, August and September. Sunshine and higher temperatures occur inland. The east side of Inverness Ridge and the beaches of Tomales Bay are sheltered from the summit of the ridge westward to the ocean, leaving sunny areas for picnicking and swimming. Inland temperatures in the summer are often 20 degrees warmer than temperatures on the Headlands and outer coast. The rainy season is December through March. Dressing in layered clothing is recommended.
