It’s hard to tell what the weather will be like day-to-day in Berlin. You can wake up to bright sunshine, leave your Wohnung (apartment) amidst deep fog and return home to an epic downpour. Other places like Freiburg may boast more sunshine than anywhere else in the country, but there is no escape from the cold. Bone-chilling, breath-stealing, icicles-in-your-nostril cold eventually finds its way to every corner of Germany. Sometimes this is only for a day or two, and sometimes this chill feels like it will never end.
And unlike places like the USA where you run from your well-heated home to your preheated car to your next heated destination, life in Europe refuses to let you hide out through the winter. There will be very cold minutes waiting for the train, the airy flat you loved in summer will turn into an ice box and the only times you’re warm are when you are sweating through your under layers on the random overheated UBahn car.
