Not sure I have an opinion on the actual formula, but I do think there are some other data that would be useful here. Precipitation frequency should also be considered. For example, Seattle is considered a "rainy" city, because it rains so often, not because it rains so much. Likelihood of major weather events is also a factor for a lot of people. I'm not a fan or tornadoes and hurricanes, so I'd prefer to live far away from places where those things have a reasonable chance of occurring.
