Viticulture in Ireland

Following on from the warmest June on record for Ireland, July 2023 is set to be the wettest July on record according to provisional data *.

Ireland had 217% of its 1981-2010 Long Term Average (LTA) rainfall in July 2023. In Newport, we had more than twice the amount of rainfall in the LTA. July 2023 also had more than 4 times the amount of rain observed in July 2022 and more than twice that observed in July 2021. The previous wettest July was in 2009 with 202% of the LTA.

Over the past 12 months, Ireland had its wettest October on record in 2022, its wettest March on record earlier this year, and now its wettest July on record.

It was cooler than average as well, which does not bode well for grape ripening although they are looking good.

What's worse, Met Eireann has just released a long-range forecast that says we are going to get weeks of rain in August.

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.

*Over the next few months, the rainfall totals from our network of voluntary observers will be returned and quality controlled, once this process is finalised, we run the analysis again, and will then confirm if July 2023 was indeed the wettest July on record (record length 83 years).

**Based on digitised data back to 1940

Open data

Yesterday, the lads built and installed the stairs to the top of the prep room where we plan to have a storage area. They also built Alex's workshop bench. Today, they were tackling the linoleum but the glue was off so they constructed the rail on the loft and the racks for the windsurfers, etc. The linoleum and the door knob/latch will be their last task. They'll be done tomorrow.

After that, we have the electrics, the sink and water to install, as well as the winery equipment once that arrives. And that's it. We will start moving more stuff in on Friday.

In the evening, we attended a pre-wedding pig roast at the Kenright's house, which was where Kirstin used to live and Alex before her. They've done a very nice job of redecorating. The water was over the road so many of the guests were brought in by boat, making it a true Ross experience. The weather held up well until about 8 or 9 pm when the skies opened up accompanied by lightning and thunder, so naturally we did not see the supermoon rise. The pig, prepared by the Quinns, was delicious. It was a lovely party.
