The climate of Leiden (the Netherlands)
Leiden is a large town located in the north western part of the province of South Holland. Leiden is an old town founded in the place where the New and the Old Rhine flow into each other. The first records of Leiden date back to the 9th century AD. In the 15th century Leiden played an important role in the Hook and Cod wars. During the Eighty Years’ war the siege of Leiden took place under the command of Duke Alva. After years of great famine the city was set free with the help of the Sea Beggars. This is still celebrated annually. During the festivities white bread and herring is handed out at the weighing house. Leiden University is the oldest university in the Netherlands; it was founded by the Prince of Orange as a reward for Leiden’s tenacious resistance during the siege. Several museums can be visited in Leiden: the national museum of antiquities, the museum of ethnology and Naturalis. The oldest botanical garden in the Netherlands, Hortus Botanicus is also situated in Leiden. A nice way to explore the city is by means of the ‘Leidse Loper’ city walking tour. Leiden has a moderate maritime climate with four distinct seasons. Summers are pleasantly warm with temperatures just above 20 degrees Celsius. Fall may be bleak with fierce winds and heavy showers. During the winter periods with subzero temperatures (during the night) are not uncommon. Precipitation is evenly spread out over the year.

The figures don’t always reflect the chance of wintry weather, extreme heat or hurricanes. That is why we offer useful extra climate information for each month of the year:
