Heat records in Ireland

 

SST anomaly off the Mayo/Donegal coast. 

June 2023 was proclaimed the hottest on record in Ireland. I suppose it's what we were anticipating, but not quite this suddenly. Our mean temperature for June via Newport Furnace was 17.4, that's 3.6C higher than in previous years. Yikes!

At least we've been getting regular rainfall lately, almost 80 mm in late June, not like the 5 or 6 weeks with not a drop of rain in May and early June. 

Our mean soil temperature at 0900 UTC was 18.6C, fully 3.8C higher than the previous means. And we only had 18 degree days below 15.5C. That's way off the norm. 

I heard a meteorologist explain the Sea Surface Temperature anomaly off our coast as being related to easterly winds prevailing during the stationary high-pressure dome last month. As the earth heated up due to high temperatures, the easterlies brought the heat over the ocean where it was absorbed due to calm conditions and little upwelling of circulation. All very strange indeed. 

It's all changed on July 1 and we are likely to have stormy conditions for several weeks. So much for getting the boat up from Kilrush.
