The weather in Mendocino is usually bright, clear, very sunny yet very cold - cold for California - meaning high 40s to low 60s during the day and high 20s to the low 40s at night. Coastal fog isn t typically a problem this time of year, as there s very little hot air/cold air interplay, but there s occasionally rain, and occasionally warm spells. When it s rainy, mud slides are the big problem, but still, rain doesn t typically come to this region until the spring.Hope that helps!
Probably pretty cold, since that s northern California. You ll get a better answer in the San Francisco forum, since that is their territory.
Wet and Cold but beautiful place.
