• Pacific Ocean Influence: The cool Pacific Ocean moderates temperatures, preventing extreme heat in the summer and keeping winters relatively mild. However, it also brings moisture, leading to fog and rain.
• Topography: The Mayacamas Mountains to the west and the Vaca Mountains to the east create a rain shadow effect, with the valley floor receiving less precipitation than the surrounding higher elevations.
• Valley Orientation: The north-south orientation of the valley allows marine air to penetrate inland, especially during the mornings and evenings, influencing diurnal temperature ranges.
