Viticulture in Ireland

Rain, blessed rain, is falling!

Showers passing through

I never thought I'd be happy that it was raining in Ireland.

If you look at the stats below, you'll see that in February we had more than twice the mean normal rainfall whereas in April we had a quarter of the mean total of only 25.5 mm. May for Newport shows 54.7, roughly half the normal, but we certainly didn't have that much in Kilmeena. Only 5.3 mm through yesterday in June so far and today we'll have much more. It's a fairly steady procession of gentle showers so it's being absorbed very nicely.

You can feel the sigh of relief from the trees, plantings and crops. The lawn was crunchy and we haven't had to mow in more than a week. Tomorrow, the grass will have grown. What's interesting is that things are growing much taller this year than usual -- irises, lupins, daisies, poppies -- really reaching up to the sun.

Finally getting some indoor stuff done today.

Was a mite windy overnight, NW

Drought in Ireland

The five-year-old Rondo vines are loaded with clusters

Weather prediction is about to become more accurate in Ireland, just at a time when there's little weather to report. We have not had any rain in ages and have been watering daily, but not in the vineyard. I hope the vines can survive the drought we are experiencing.

The three-year-old Solaris vines are looking good.

The earth is parched and the leaves that blew off the trees in the last storm are so dry that everywhere you take a step outdoors is crunchy underfoot. The cats are actually scaring themselves with the noise. This is a truly unusual situation for us. Midday is silent as the cats take siestas in the shade of the trees, birds stop flying and even the insects settle down somewhere. There are many more insects this year than last -- all different kinds including many butterflies flitting about. Everyone is coming to the oasis to drink and bathe but the water level is way down.

It's looking pretty good for no rain in weeks.

The hottest day of the year so far was yesterday and reported in Furnace, Newport just a few miles from here at 26.9C. Irish Water is about to restrict watering and there's little respite in the forecast. So all we can do is pray and go paddling around Clew Bay. It's gorgeous out there and much cooler on the water. See you later.
