Climate of Guernsey

The island of Guernsey is one of the Channel Islands. Like Jersey, it is fairly close to the French coast. The temperate maritime climate is therefore very similar to the climate of the Brittany region in France. Guernsey has milder weather in the winter months compared to the interior of Brittany. Under the influence of the relatively warm seawater, it cools less in winter than on the European mainland. Due to its favorable location on the east coast of Guernsey, the capital Saint Peter Port even has a remarkably low number of days that it actually comes to frost. Even in the coolest months, temperatures often remain above freezing at night. With an average of 4 to 6 degrees above zero, it is about five to seven degrees warmer in Guernsey than in the Netherlands.

Mild winters

The mild winters and the fairly stable precipitation pattern ensure that subtropical plants such as palm trees can survive on the island of Guernsey. Although it could theoretically be possible, Guernsey does not produce wine on a large scale. The winter months are not only fairly warm, the sun also shows itself regularly for this region. In the darkest months, at least about two hours of sunshine per day are recorded. The summer months are good for an average of eight hours of sunshine per day. With an average of 35 to 45 millimeters of precipitation per month, the summer is drier than the rest of the year. In fact, in terms of precipitation statistics, Guernsey does significantly better than many Western European countries in the summer.
