The climate of Isle of Man
The Isle of Man, as it is called in English lies in the Irish Sea between England and Northern Ireland. The Isle of Man neither belongs to the United Kingdom nor is it part of the European Union. With less than one hundred thousand inhabitants Man is one of the smaller countries in Europe. The Isle of Man has a moderate maritime climate with relatively mild winters and cool summers. In the summer months the temperature does not often rise above twenty degrees and summer days of twenty-five degrees or more are relatively rare in this isle, which on a yearly basis has to cope with more than a thousand millimeters of rain. That is because the Isle of Man lies on the supply route of depressions which are supplied with the jetstream over the Atlantic.


The Isle has a shape of frequent occurrence with mostly low areas along the coast and hills and a few mountaintops in the centre of the Isle. The differences in height make the north-westerly coastal areas generally somewhat wetter and the south-easterly part, where you can find the capital of Douglas, somewhat drier and somewhat warmer in the summer months.

Mild and wet winters
Due to the relatively warm sea-water surrounding the Isle of Man and its situation between England, Scotland and Northern Ireland it seldom gets severely cold here in the winter. The temperature during the daytime is on an average between 5 and 8 degrees centigrade and at night freezing-point is often not reached along the coast. In the more elevated areas, central in the Isle, it may cool down a little during the night. Particularly with a clear sky it can freeze some degrees. In general it is grey and wet in the winter and autumn. Particularly the months of October, November, December and January have many days with rain, in which the total monthly amount of precipitation comes to an average of 150 to 200 millimeters of rain.

More climate information
Climate figures come in handy but do not offer a total impression of the climate and the possible weather circumstances within a particular period. You cannot often find in figures how big the chance is of wintry weather, (extreme) heat or hurricanes. Therefore we monthly offer useful extra climate information.
