Specifically, I'm interested in humidity and temperature, but weather, altitude, and any other conditions we are evolved for can be included.

However, has there been enough time for people of different "races" or ethnicities to differentiate based on region? It's theorized that the epicanthic fold evolved for climate reasons, for instance.

I want the know the optimum conditions my body is adapted for, but maybe this is futile without knowing where my ancestors came from?
