First Frost Dates in Ireland
3:12 pm September 14th, 2009Last year, we had the first frost on the 27th of October (and here’s a fantastic frost photograph by Wojciech Szczygieł, taken near Courtown in Co. Wexford).
Average first frost dates are hard to find online, but the general feeling seems to be that up until the mid-nineties, first frosts happened in late September. These days, as evidenced above, they don’t happen until late October, and sometimes early November. However, last winter set into being fairly cold following the late start.
The lowest temperatures in Ireland - including the record of -19.1°C in 1881, at the rather stunning Markree Castle, which is well-equipped for winter weather - have always happened in January, according to Met Eireann. So it’s pretty unlikely that we’re going to get a drop to sudden very cold temperatures. Nevertheless, the possibility of an early frost, in comparison to the last decade at least, is out there - there are predictions of temperatures of 4°C for the end of September already. So watch those tomatoes!
