The east side of Inverness Ridge and the beaches of Tomales Bay are sheltered, with sunny areas for picnicking and swimming. Sunshine and higher temperatures can be found inland. Heavy fogs are most common in July, August and September. The fog can blanket the ocean for more than 80 km (50 miles) off the shore and often smothers the beaches. The air cools, condenses, and produces fog. As warm moist air from farther offshore travels east it encounters these frigid coastal waters. During most of the year, the water temperatures near the coast are lower than that of the ocean farther to the west. Headlands and beaches on the Pacific Coast are subject to frequent heavy fogs. Winds are much lighter on the eastern side of the Inverness Ridge, but it is an unusual day that does not bring afternoon breezes to Point Reyes. While wind speeds tend to average about 32 km/h (20 mph) at the Lighthouse on the Point, storms often bring winds with gusts of 112 km/h (70 mph), with the strongest winds measured at 213 km/h (133 mph). The strongest winds occur in November and December during occasional southerly gales. There are usually moderate to strong winds on the exposed headlands and outer beaches. While this is the general trend, the weather can vary greatly depending on which side of the Inverness Ridge you are visiting. Warm dry summers and cool rainy winters characterize the Point Reyes Peninsula's climate, similar to the type of climate that prevails on the Mediterranean.
