In regular conditions we get plenty of rain up here too. Some of my regular rides are normally some of the highest rainfall areas in Australia (fact). Just lately it hasn't been so, and we have the very real prospect of running out of water completely this summer. By comparison, riding in the rain now doesn't seem that bad.
I've never really understood why people don't like rain. But then, it's not exactly cold in Queensland. Maybe I'll be in for a rude shock one day!
