Climate / weather

The climate on the island of Mön is determined by the meeting of the Baltic Sea and North Sea, as well as by the Gulf Stream. It’s rarely really hot here and rarely really cold.

Average minimum and maximum temperatures in the year:

In the first quarter of the year, minimum temperatures of -1 to -3 degrees Celsius are reached on average. The average maximum temperatures will be around 2 to 5 degrees Celsius.

The second quarter is already a bit warmer. The average minimum values there are around +7 degrees Celsius. The maximum values are from 10 to 19 degrees Celsius.

From July to September it is warmest on the island of Mön. Then an average of lows of 11-15 degrees Celsius are reached. The maximum temperatures are 18-22 degrees Celsius.

The end of the year (October to December) is then cooler again. Low temperatures of 1 to 7 degrees can be expected. The associated maximum values are 4 – 12 degrees Celsius.

Average water temperatures:

The water temperatures behave similarly to the air temperatures listed above. From January to March the water is cool, at 2 to 3 degrees Celsius.
As the year progresses, the water temperatures rise to up to 14 degrees Celsius in the second quarter. The third quarter is also the warmest in terms of water temperatures. Temperatures of around 16 degrees Celsius can be expected here. Towards the end of the year, the sea cools down again to 6 degrees.

Hours of sunshine per day:

At the beginning of the year, up to one hour of sunshine a day can be expected. This applies in particular to the months of January and February. In March the hours of sunshine can increase to 4 hours a day. A further increase to around 5 hours is possible in April. The months of May to July have the greatest chance of seeing the sun. An average of 8 hours of sunshine a day can be expected here.
From August the daily hours of sunshine slowly decrease again.
The low point will be reached in November. No measurable hours of sunshine are achieved here.

Rainy weather:

The year starts with a lot of rainfall. In January, up to 17 days of precipitation are reached. In the following months, 11-16 rainy days per month are also achieved. The month of May has the least rainy days (11). Like January, December has an average of 17 rainy days.


With reference to the information above, it can be said that midsummer on Mön island is quite short. The climate is rather cool for summer conditions, as is typical for the Baltic Sea. As in Germany, the days are still nice and warm in August and September, but the evenings are significantly cooler.

The winters in this region are rather mild, so that it rarely goes very far below freezing point. This climate is particularly suitable for people who suffer from asthma or rheumatism.
