Sonoma County Weather
November 14th, 2009 categories: Personal Notes
Sonoma County Weather is one of the reasons people come to this lovely region of California. Another reason, the wine, is a direct product of the weather. Without our unique brand of weather, the grapes would not grow the way they do, and the region would not be known as such a great wine region.
Many of our clients who come from out of town often ask about the Sonoma County weather. Since it is a recurring question (one of the reasons we write some blogs is because we do get recurring questions) I decided to write an article explaining a little more about the weather here in Sonoma County.
Sonoma County really does have a lot of different weather patterns. For the purpose of this article, I decided to use the averages (for the graphs below) from Santa Rosa, the county seat of Sonoma County. We also decided to use Santa Rosa as representative because Santa Rosa is near the geographic center of Sonoma County, and is the most populated area.
Below is a graph of Average Sonoma County Temperatures…showing all time highs, all time lows, average highs and average low temperatures, all by month. As you can see, the low temperatures are very stable, rarely going below 40 degrees, and rarely getting above the low 50’s. The weather here is usually dry, and even though the lows are in the mid 50s in the summer, the lack of humidity makes it feel warmer, and great for a morning workout.
