By most sources, it is the warmest place in Germany. Under the Köppen system, Ihringen closely borders an incredibly rare 48°N humid subtropical climate (Cfa), with mildly cold winters and long, hot summers. The city is close to the Kaiserstuhl, a range of hills of volcanic origin located a few miles away which is considered to be one of the warmest places of Germany and therefore one of the most important viticultural area.
