Description of Typical Weather by Season
The moderating influence of the Pacific Ocean creates a climate with no great extremes of heat or cold. Any season can bring interesting weather during your visit to Point Reyes National Seashore. Come prepared!
Although there is very little rain during summer months, there is often dense fog. If you are visiting Bear Valley or Tomales Bay, expect patchy morning fog to burn off by mid-day. Afternoons are often sunny and warm with a light breeze. By contrast, the beaches and headlands are often 20 degrees cooler with heavy fogs common throughout the day in July, August and September.
The coastal areas of Point Reyes experience some of the clearest days in late September, October and early November. The occasional storm will start rolling through in late October, bringing clouds, wind, and rain. The strongest winds occur in November and December during occasional southerly gales.
The heaviest rainfall occurs in the winter months. Come prepared for rain and drizzle to possibly last for several days. More rain falls east of Inverness Ridge than on the west side. In between winter rains, it is often sunny, calm, and cool.
Most spring days are windy and even Bear Valley and Tomales Bay experience stiff breezes. Expect cool temperatures in March. By late May and early June, temperatures can be quite warm on the east side of Inverness Ridge.

Storm Damage to Lighthouse Weather Station Tower
In May 2013, powerful winds caused the Lighthouse Weather Station Tower to partially collapse. The images to the right show what the weather station looked like before and after the wind storm. The top of the tower collapsed, rendering the anemometer and Yagi antenna inoperable. Information from the weather station will be unavailable until a new tower is constructed.
