It's back! The big freeze is on again.

One week ago on the streets of Prenzlauer Berg coffee drinkers were lazing about in the late autumn sun, talking of an "Indischer Sommer". At 23 degrees Celsius, it was the warmest 26th October in Berlin's history.

But now in November, the locals are nowhere to be seen - sub-zero temperatures have frightened everyone inside and even the sun has decided to not come out this weekend. For the next few months the forecast looks good for indoorsy-types: Meterologists say that a warm October means a cold winter. al
