Influence of Coastal Geography

Patterns of Fog and Overcast Conditions

San Rafael, located in Marin County, experiences notable weather patterns influenced by its proximity to the coast. Fog and overcast skies are often a part of this climate, especially during certain months. Precipitation variability also plays a role in the region’s weather dynamics.

Frequency of Foggy Days

San Rafael is subject to fog primarily during the summer months. These foggy days are typically caused by the marine layer that rolls in from the Pacific Ocean, affecting visibility and creating cooler temperatures.

Days with fog are common between late spring and early fall. Observers have noted that the fog tends to be more prevalent in the mornings and usually diminishes by midday, allowing for clearer skies in the afternoon. This regular pattern contributes to the unique microclimate experienced in the area, setting it apart from regions further inland where fog does not have as significant an effect.

In Marin County, including San Rafael, precipitation varies notably throughout the year.

Winter months receive the most rainfall, which helps alleviate the dry conditions of summer.
