It’s snowing here in Berlin. And I already thought, that we wouldn’t have any white color out there before Christmas Eve. In order to check the weather forecast for the next days, I found www.openweathermap.org. A really nice tool to get current weather data and some more informations based on more than 40.000 weather stations around the globe. Best of all, openweathermap.org provides APIs for several weather-data excerpts for free.
