The 2022–23 European windstorm season was the deadliest and costliest European windstorm season on record, mainly because of the impact in northern Libya of Storm Daniel, which became the deadliest and costliest medicane ever recorded as well as the deadliest tropical or subtropical system worldwide since 2013.
The 2022–23 season was the eighth instance of the European windstorm naming in Europe. It comprised a year from 1 September to 31 August, except in the Eastern Mediterranean Group which is shifted a month later and as such Storm Daniel was named on 4 September and lasted until 12 September, and Storm Elias existed two weeks later and overlapped with the first storm of the succeeding season named by Greece. This was the fourth season where the Netherlands participated, alongside the United Kingdom's Met Office and Ireland's Met Éireann in the western group. The Portuguese, Spanish, French and Belgian meteorological agencies collaborated for the sixth time, joined by Luxembourg's agency (South-western group). This is the second season where Greece, Israel and Cyprus (Eastern Mediterranean group), and Italy, Slovenia, Croatia, Montenegro, North Macedonia and Malta (Central Mediterranean group) named storms which affected their areas.
