This month is set to be declared as the hottest ever June on record in Ireland, Met Éireann has said.
The previous record for this was held for 83 years, with the sixth month of 1940 previously being the highest recorded.
June 2023 is expected to be more than half a degree higher than this.
Provisional data has shown that Ireland experienced its first June with a daily average of 16C.
The highest temperature recorded this year so far was 28.8C at Oak Park in Co Carlow on June 13th. This marked the third year in a row that a temperature at or above this was noted in Ireland.
Met Éireann climatologist Paul Moore told PA that while the weather has dropped in recent days, it does not impact the month being record breaking.
He added: “This year’s particularly warm June is part of an observed warming trend and our research shows that this trend will continue. Our recently published Translate project provides a reminder that right across society we need to understand and plan for a changing climate.
“An average monthly temperature of greater than 16C has been seen in July and August, but never before in June. June 2023 was well above normal due to persistent warm days and nights.
“Twenty-three of 25 Met Eireann primary weather stations are showing their warmest June on record. In early June, cool easterly winds on the east coast meant that Phoenix Park and Dublin Airport stations were cooler but they still show their warmest June since 1976.”
