July 2025 ended up fairly average, with the exception of one observation: Degree Days Below 15.5°C were lower than the LTA and far below those of the last three years. That means the daily temperature didn't fluctuate as much as in prior years. Could that be the reason the grapes are maturing so much earlier?
Storm Floris which brought us more than 15 mm of rain all told, pushed us over the LTA for rainfall. Our mean temperature was average but soil temperature was higher than previous years.
I also discovered a cool new resource from Met Eireann. The Weather Observations Website (WOW) https://wow.met.ie/ provides real-time weather reporting.

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.
