A Mediterranean climate best describes the Napa Valley of California.  Warm dry summers and wet cool winters, perfect for growing the award winning grapes used in the wine making, is what you can expect when visiting the area.  Rain is rare during the growing season, with most occurring between October and May. January and February are usually the wettest months.  The fog which characterizes the region keeps the vines cool and maintains the natural acidity in the fruit.  A history of volcanic eruptions and earth movements means that soils are diverse in the area.  Summers are always sunny and warm, but never uncomfortable due to the influence of the nearby Pacific Ocean and low humidity levels.  Autumn is a spectacular time of the year in the Valley when vines are in full color and it is harvest time.
