Although the winter is not very cold for the latitude, it is often humid, windy and rainy. There may be relatively mild periods, when Atlantic currents prevail, and other colder periods, when the temperature drops below freezing and it can snow.
Sometimes, there can be cold spells, in which temperatures can drop as low as -10 °C (14 °F) or even below. In fact, Scandinavian high pressure systems can reverse the normal circulation and bring very cold periods, which in the past were more frequent. The cold record is -18.5 °C (-1.5 °F), set in February 1972. More recently, the temperature dropped to -14.5 °C (6 °F) in March 1986 and January 1987, and to -11.5 °C (11.5 °F) in February 2012.
Even in spring, until April or the first half of May, there is often cold and unstable weather. In April, there may still be some snow showers.
In summer, the temperatures are generally pleasant and lend themselves to outdoor activities, although there are cool and rainy periods, and sometimes thunderstorms can break out.
At times, hot periods can occur, generally of short duration, which in recent years are becoming more frequent due to global warming, and in which the temperature can exceed 28 °C (82 °F). However, given the latitude and the short distance from the sea, the heat is less intense and lasting than in the central-southern German plains. On the hottest days of the year, the temperature typically reaches 29/30 °C (84/86 °F). The highest record is 34 °C (93.2 °F) and was set in August 2022.
On average, there are around 1,840 sunshine hours per year. Here are the average sunshine hours per day.
