Northern California is an entirely different matter. Up here, it rarely gets above the high 70's. I live on the coast in Eureka, which has "natural air conditioning". The temperate rarely varies + or - 20 degrees of 50 degrees farenheit. Rain in common for about 8-9 months of the year. We had thunderclouds today, this being May 12th. I wouldn't expect the weather to start feeling Summerish until late June, at the earliest.
