Greece recorded the wettest May of the last 15 years following a winter with low rainfall and a relatively dry spring for most parts of the country, with the only exception of the west. Based on the data of the National Observatory of Athens/Meteo.gr, heavy rainfall was recorded:
· in the Ionian islands,
· on the mainland,
· in Crete,
· in the Dodecanese
The National Observatory of Athens explained that it is not uncommon to have showers and thunderstorms in May, especially during the evening hours.
Heavy rainfall and a large number of rainy days were also observed in 2007, 2011, 2016, 2017 and 2018.
