Weather
The Napa Valley enjoys a Mediterranean climate, typified by cool mornings, warm days, low humidity, and refreshing evenings.

Year-round, our morning lows average 45F with afternoon highs averaging 71F. With virtually no wind in the mornings, the sun makes our average low of 45F feel warmer than it sounds. With the exception of a few months, shorts and pullovers are standard morning attire. 

Here's a monthly breakdown of our Average Highs and Lows:

From April 1st to November 30th, rain is nearly non-existent. Our winter “rainy season” is mild and occurs between December and February. We tour "rain or shine." If rain occurs on the day of your scheduled bike tour, our guides will ride if you want them to, or we will tour by van instead.
