EUROCONTROL: Aviation’s summer impacted by the weather

Europe experienced extreme weather in July and the weather-related ATFM delay during this month was over two and a half times the 2022 figure. The main impact has come from convective weather (thunderstorms etc.), notably in Germany, Hungary and Serbia. At airports, the largest weather delays have been at Frankfurt, Gatwick and Munich.

Overall, without the weather element, ATFM delays per flight reduced by nearly a quarter to 2.5 minutes per flight (despite traffic growing 7%). When the impact of the adverse weather is included, they increased marginally from 3.9 to 4.1 minutes per flight.

July 2023 saw traffic 7% up on average compared with July 2022, with total flights in the month exceeding 1 million for the first time since September 2019. In fact, in around half of EUROCONTROL’s Member States, traffic levels were at or above those of July 2019 – particularly in south-east Europe.
