Monthly climate stats

 

As I already reported, Met Éireann has confirmed that May was officially the hottest May in recorded Irish history. The rainfall amount was higher than average, but not as high as it was last year. The temperature was 1.2 degrees C higher than the LTA. 
August proved more average. Rainfall was slightly higher than the LTA, temperature was somewhat higher, and soil temperatures were slightly higher than normal. Otherwise, it was uneventful.

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.
