The description:
Climatology gives you climate information for anywhere on Earth: temperature, rain and sunniness. Whether finding where are the warm, dry places to go on holiday in December, or avoiding rain for your wedding, to finding out what the climate is like in Kazakhstan in April, > Climatology allows you to discover the information you want.
Sounds pretty neat, and looks nice too.
It’s made by Microsoft, which is the biggest surprise of it all. (Kind of like Forecast.io’s Time Machine feature.)
