Concerning rainfall, 2018 was a year of contrasts: the first half of the year saw excess precipitation in much of the southern half of ■ Europe (including France), a shortfall in Germany and part of Central Europe, and close to normal levels in the North of Europe; the second half of the year saw a serious shortage of precipitation over much of ■ Europe, particularly France, Germany and all of Scandinavia. Annual rainfall for 2018 thus registered surplus levels across all of southern Europe and shortages in Central Europe and Scandinavia.
