This map was created by Perrin Remounted in 2023 as part of the initiative #30DayMapChallenge.
The map shows average annual rainfall in Europe. The author uses different shades of blue, with the darkest shades indicating the places with the highest rainfall and the lightest shades indicating the most arid areas. The data is represented with a grid resolution of five kilometres per side.
As a curious fact, the author points out that London has only 600 mm of annual rainfall, less than cities such as Rome, Bordeaux or Naples, despite London's reputation for being a rainy place. This is because the English capital has less intense rainfall over longer periods, while other cities such as Naples have more intense rainfall over a shorter period of the year.
The map shows the importance of mountains in terms of rainfall, as is the case in the Caucasus, the Alps, the Balkans and the Pyrenees, as well as how decisive exposure to the Atlantic Ocean is, as can be seen in the north of the Iberian Peninsula, Ireland, Scotland and Norway.
The rainiest place in Europe is Cetinje, Montenegro, with 3,303 mm of rainfall per year. At the opposite end of the scale is Almería, Spain, with just 200 mm of rainfall per year.
