You could be hearing the words “fierce mild” a lot over the coming days.

That’s because, according to Met Éireann at least, temperatures will reach as high as 17 degrees at times during a week that’s set to be a bit of a mixed bag on the weather front. Monday will start off cloudy and damp, but there will be sunny spells in many places in the afternoon, with temperatures reaching a maximum of 16 degrees. Spells of patchy light rain will develop on Monday evening, but Tuesday and Wednesday are set to be mild and bright once again, with highs of 17 degrees on Tuesday and 16 degrees on Wednesday. It’ll start to cool off a little from Thursday onwards with average temperatures of between 9 and 12 degrees, although conditions will remain dry for the most part before it becomes colder still on Thursday night, with the possibility of frost in places. The current forecast for Friday, St. Patrick’s Day, is for a chilly start, with light rain in the west and north turning heavier as the day progresses. If you’re out and about, best bring a warm coat as temperatures won’t go any higher than 10 degrees, with freshening southwest winds likely to make it feel even cooler than that.
