Why can't the weather be a critical issue that only works in combination with the other factors? My intuition says that Silicon Valley wouldn't be possible in a beach town nor in a place that's too cold or too hot, simply because of how much the weather would distract you from work. The great thing about the weather in the Valley is that it's pleasantly bland (or blandly pleasant?). But I think it's very likely that the weather doesn't matter at all if you don't already have some equivalent of the Stanford-Berkeley nexus and California labor law and a lot of very rich people willing to make high-risk investments.
