Climate:
Jersey is the largest of the Channel Islands and belong to Great Britain. They are found a short distance from the French coast of Normandy. The climate of Jersey is very similar to that of the neighbouring island of Guernsey, although it is slightly more exposed to both cold and heat, since it is closer to the continent. Winter, from December to February, is quite cold. Temperatures are not so low, but wind and humidity can increase the sensation of cold. The sky is often cloudy, and rainfall is frequent. Sometimes, intense Atlantic depressions can cause storms. Snowfalls are relatively rare and not abundant; usually, cold spells are not intense and do not last long. However, the cold record is -9°C. In spring, from March to May, the temperature slowly rises, and Atlantic fronts become a bit less frequent. In May, it is often still quite cold, especially in the first half of the month. Summer, from June to August, is cool, with quite frequent rains, but also with a bit of good weather. The temperature may reach 25°C and the highest records are 36°C set in July 2019 and 36°C set in August 2003. Autumn, from September to November, is grey, cloudy and rainy, and with each passing week, it gets progressively colder. In November, the wind is often moderate or strong.
