You would have thought that the French city where it rains the most is in Brittany… but that is not the case! Vacation rental site Holidu conducted a study on French cities with the highest rainfall between 2009 and 2022. Here are the results.
Before going on vacation, many of us analyze the weather at our destination… especially in summer when we decide to stay in France. For several years now, temperatures have no longer reflected the seasons. The proof is with this month of August 2023 which was synonymous with rain and grayness when it should normally rhyme with sun and heat.
Thus, the vacation rental site Holidu used data from World Weather Online in order to carry out a study and establish a ranking of the cities in France where it rains the most during the year. Against all expectations, the rainiest city is not Lorient or Lille… but is located in Isère.
