The Baltic Sea island of Usedom dropped to an icy -29.1 degrees in the early hours of Monday, marking a record low for Germany this year.
But other regions weren't far behind. Ueckermünde in the northeastern state of Mecklenburg-Western Pomerania hit -28.7 degrees, the Saxon town Deutschneudorf dropped to -28.2 and Oberstdorf in Bavaria’s Oberallgäu recorded -28.1.
Berlin and the surrounding state of Brandenburg froze through the coldest night in 25 years, with temperatures far below -20.
The warmest part of the country remained the Lower Rhine region, where Duisburg recorded a low of -7.8 degrees.
The DWD warned the worst of the brutal cold gripping the country was not yet over.
“Tuesday will be even frostier,” said DWD meteorologist Christoph Hartmann.
With daytime highs expected to range between -12 to -7, only the northwest of the country is expected to remain snow-free on Tuesday.
Wednesday will be “warmer” but still far below zero.
