Haha, did someone actually tell you the weather is fine? I was born in Texas and I've lived in Austin for 13 years and I've always thought the summers are unbearable. Although my perspective is tempered with what I experienced around the gulf, in Mississippi and Florida. The humidity there is so bad I literally don't think it's fit for human settlement.
San Francisco is one of the most humid cities in the US (so much that mold can be a problem in some cases). Relative humidity is on average higher than Wash DC --but lower than Port Arthur, TX.
Yes, but its neither particularly hot (so it doesn't tend to be muggy), nor particularly cold (its cold for the densely populated parts of California, but that's not saying much), so the humidity isn't much of a problem.
Hence one of the reasons it waa attractive before it was a center of the tech industry.
