For many European countries, September 2023 was their hottest September on record.
France, Czechia, Latvia, Denmark, Poland, Belgium, Germany, Austria, Switzerland, Finland, Lithuania, all had their hottest September.
And it was joint warmest for the UK and Ireland.
Meteorologists from the Netherlands and Croatia both tell me that September 2023 was their second hottest.
It was a pretty exceptional month, especially when you consider how miserable the weather over July and August had been.
