August ended with less rainfall than in the previous 3 years, but equal to the mean of 1981-2010. (Why they chose two earlier decades, I do not know.) August also saw the onset of veraison, or the beginning of the grapes turning colour.
Meanwhile, September started with torrential downpours and flooding in Clifden, which is a short distance away in Connemara. We didn't have quite as much, but we still had a lot overnight and all day. Met Eireann had forecast 25-35mm rain for our area. And more to come. The air and soil temperature were almost a full degree higher than prior years. It certainly feels like climate change.
Did I mention that we now have native honey bees? Grapes don't need them as they self-pollinate, but the orchard should benefit enormously. Plus, I won't have to walk around with a paintbrush doing the pollinating myself. The suit can double as protection against coronavirus transmission. Just suit up and everyone will steer clear on the streets.
