Summer    Spring & Fall      Winter

The climate in Sonoma County is wonderful for cycling most of the year. 

Because of the coastal influence and coastal mountains, there are many micro-climates and weather is very changeable. For this reason we suggest dressing in layers and always bringing extra clothing for the cold and extra water for the heat.

Take a look at the seasons below to get an idea of what type of weather you might expect and some recommendations as to what to wear.

SUMMER (MID MAY-OCTOBER) -

In the summer months the chance of rain is very rare.

Inland, the daytime highs are usually in the 80's and 90's but the nights and mornings cool into the 40’s and 50’s as the coastal fog comes in. 

In the mountains there are areas which can be 10-15 degrees hotter than the valleys- always bring extra water.

On the coast it can be windy, cool and foggy anytime even in mid-summer- always bring a vest or jacket.

Light long pants and/or shorts (cycling shorts are more comfy!)

SPRING AND FALL (MARCH, APRIL, MAY AND OCT, NOV) -

On the shoulders of the dry summer and wet winter, the spring and fall promise generally beautiful weather- with a chance of an occasional storm coming through (though the frequency and duration are much less than in the winter months). The daytime temperatures are in the mid 60's and 70's with the evenings and early mornings quite cool in the low 40's.

Winter is the rainy season in Northern California.  There is plenty of rain and stormy weather and it’s also notoriously unpredictable and often times wonderful.  You could experience a week of solid cold rain or days of beautiful sunshine and temps in the 60's and 70's.  If you’re planning a trip in the winter we definitely recommend being prepared for all types of weather.
