Well this is just based on my experience. I didn’t measure or compare anything related to the weather. In Bremen, I get thirsty easily. And if I don’t drink much, my lips and skin will get dry easily. In Berlin, I don’t experience this. I don’t get thirsty easily although I have walked for some hours. And surprisingly my lips and skin are not dry because I drink less.
As I write before, the weather during New Year celebration was nice. It was warm and the sky is clear. But in the next day, there’s snow rain! And it keeps raining almost the whole day, covering everything to become white! What a drastic chance. But I guess, as we’re in Indonesia have rainmaker/ controller, in Germany they have snowmaker/ controller!
