Climate Statement for November

 

It was the fifth wettest November on record. It wasn't imaginary. The temperature was slightly above the LTA. The national mean air temperature of 8.61°C (using the Island of Ireland dataset) placed October 2025 21st warmest in 126 years.  8.61 °C is 1.54 °C above 1961-1990 LTA and 0.65 °C above the most recent 1991-2020 LTA. The national average rainfall of 189 mm ranked 5th wettest in 85 years and 136% of its 1991-2020 LTA. It was a very mild first half, a cooler second half. Storm Claudia was followed by an arctic blast that caused a swing in conditions. 

Alex dug another trench across the field above the donkey shed yesterday. The Golf Course has cancelled all play as it's too soggy. I haven't ventured into the vineyard in the past week. I'll check on it tomorrow. 

Climate Statement for October 2025

 

Met Éireann has proclaimed that October was "Mild, dull and wet overall".  That about says it all. The only outstanding feature of October was Storm Amy. The highest gust recorded during Storm Amy was reported at Malin Head, Co. Donegal, with 148 km/h, and the month’s highest 10-minute mean wind speed was 111 km/h, also at Malin Head during Storm Amy.

Only 20 days to go before the days start getting longer...

Monthly data for November

We received significantly more rain in November compared to the Long-Term Average (LTA), but the amount was equal to what we experienced in 2023. The air and soil temperatures were comparable to the past few years. Unlike October, when solar radiation was significantly below that of recent years, in November it was comparable. I suppose that will make a difference for our solar energy generation. 

December has started off considerably damper than expected. The forecast was for nice weather in the West but it's afternoon and the rain has been relentless since we awoke this morning.

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.
