Winter is officially over. That is according to Met Éireann, which said it was colder than average due to the North Atlantic jet stream being displaced to the south for December, January and much of February.
Commenting on the season, Met Éireann meteorologists said the shift of the jet stream south had brought cooler than average temperatures for the majority of the winter, but milder conditions dominated in the second half of February as the jet stream moved north again.
