That's because you've chosen not to read about it. Location is one of the most important things they think about for data centers and there are plenty of articles on the subject.
Here's a recent article:

“We set out looking for a place where we could expand into gigawatts pretty quickly, and really get moving within that community on a large plot of land very quickly,” said Rachel Peterson, vice president of data centers for Meta. “We looked at finding very, very large contiguous plots of land that had access to the infrastructure that we need, the energy that we needed, and could move very, very quickly for us.”
To answer the question you're implying, surrounding temperature is pretty minor, the cooling required is orders of magnitude higher, so power access is more important; You'll frequently find them located near sources of energy.
Similar reason to why a lot of chemical manufacturing is in Louisiana.
Hurricanes on the other hand will still be a very real thing.
I get where you're coming from but still I find funny in so many levels that the literal speed limit of the universe is too slow for our mundane (or even banal in FB case) needs. the universe isn't good enough to our need to move bullshit across the globe. surreal.
In the same vein it would be awesome if this _need for speed_ would materialize in infinite funding of neutrino based communication research.
