CURATED HISTORY
Events supported by real evidence
Every page separates observations from reanalysis and explains what can—and cannot—be concluded from the available data.
Storm Daniel and the Thessaly floods, 2023
Daniel was a multi-day extreme-rainfall episode. The slow-moving system kept heavy rain over the same catchments while runoff accumulated across the Thessalian plain and around Lake Karla.
4–7 September 2023 · Thessaly, Magnesia, Sporades, Evia and PhthiotisHeatwave episodes in Greece, July 2023
Successive hot spells kept temperatures very high through much of July. The event is important not only for peak temperature, but also for the sequence of hot days and nights.
Mid to late July 2023 · Mainland Greece, the Aegean and Ionian islandsMedicane Ianos, September 2020
Ianos organised over the warm Ionian Sea and reached western Greece with strong winds and heavy rain. Moisture and rainfall then shifted towards central parts of the country.
16–20 September 2020 · Ionian Sea, western Peloponnese, Central Greece and ThessalySnowstorm Elpida, January 2022
Two successive disturbances carried very cold air from north to south. The second was stronger and produced snow even at low elevations and near the coast in eastern Greece.
22–26 January 2022 · Macedonia, Thrace, Thessaly, eastern Central Greece, Evia and the AegeanMedicane Zorbas, September 2018
Zorbas developed over the southern Ionian and showed tropical-like characteristics before affecting the Peloponnese and areas farther east. Its prediction carried substantial uncertainty in both track and intensity.
27–30 September 2018 · Southern Ionian Sea, Peloponnese, Attica, Evia and the western AegeanMandra flash flood, November 2017
Heavy rain over small, steep catchments west of Athens produced very rapid runoff into built-up areas. The event is a clear example of a local flash flood with a disproportionately large impact.
15–17 November 2017 · Mandra, Nea Peramos and western AtticaMETHOD
