Today it was 83 degrees in downtown Seattle, humid, and the sun was blistering. Our UV index is lower than, say, Africa, but I still got a sunburn while wearing sunscreen at work. Clouds do not exist from July 5th to October 9th. And we don't have air conditioning. Summer rain is a myth, save yourself.
So, here in CO, the mountains tend to be about 20 degrees cooler than the plains... and at 10,000 feet it was in the low 80s for the past few days. The UV index up there will be at nearly 12 tomorrow and 11 down on the Front Range.
Trust me, even in the summer, Seattle would be an improvement.
