Climate - Fehmarn (Germany)

The climate of Fehmarn is sub-oceanic, humid and rainy, influenced by currents from the Atlantic and the North Sea, with cold, gray winters and mild or pleasantly warm summers.
The island is located in northern Germany, a short distance from the Schleswig-Holstein coast, and is connected to the mainland by a bridge.
The wind blows frequently, and can be intense, especially from November to March. Not surprisingly, windsurfing and kitesurfing are practiced here.
The average temperature of the coldest month (January) is of 1.8 °C (35 °F), that of the warmest month (August) is of 18.1 °C (65 °F). Here are the average temperatures.

Precipitation amounts to 550 millimeters (21.7 inches) per year: so, it is at an intermediate level. It ranges from 30 mm (1.2 in) in the driest months (February, April) to 65 mm (2.6 in) in the wettest (August). Here is the average precipitation.

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 heat record is 33.5 °C (92.5 °F), set in July 1959.



On average, there are around 1,840 sunshine hours per year. Here are the average sunshine hours per day.

The sea temperature ranges between 2 °C (35 °F) and 18 °C (65 °F). So, it never becomes warm for swimming (except for tourists from northern Europe). Here are the average sea temperatures.

Best Time

The best time to visit Fehmarn runs from mid-May to mid-September, since it is the warmest and sunniest period of the year. Sometimes, it can be hot in July and August, while in other circumstances, nights can be cool even in these months, so it can be useful to bring a sweatshirt or sweater and a light jacket.
