How did 2023 weather stack up in Ireland?

December 31, 2023 in Kilmeena

The annual data for 2023 published by Met Eireann shows we had more rain, higher mean temperature, higher mean soil temperature, and fewer degree days below 15.5C. Yep, it's warming. 

The remaining values were somewhat comparable to averages for the past three years.

Notes on the Data

Evaporation and PE data are calculated using Penman/Monteith formulae.
The ‘LTA’ (referred to within a table) is average for the climatological long-term-average (LTA) reference period 1981-2010.
Data updated daily at Mid-day.
