How Mullaghmore compares
Against the 321 Irish towns and city neighbourhoods of 2,500 or more, each read from Met Éireann’s grid at its own centre, and its place among towns of 2,500+ in County Sligo.
Warmer than it used to be
Mullaghmore’s 1991–2020 average is 0.2°C warmer than 1981–2010’s. The biggest change is in February (+0.4°C).
A year’s rain is 1,146 mm, up 5% from 1,094 mm.
Change by month
The two periods share 1991–2010, so the gap is a decade’s step, not the change between two separate 30-year periods.

Where Mullaghmore’s numbers come from
Averages over 30 years, not a forecast: the town’s own from Met Éireann’s grid, the frosts and degree days from its nearest station.
- Temperature and rain: Met Éireann’s 1991–2020 averages on its 1 km grid (Climatological Notes 22 and 23), read at the grid point nearest Mullaghmore’s population centre (0.7 km away).
- Weather station: the nearest of Met Éireann’s 25 synoptic stations, Finner, 14 km east, from Met Éireann’s station list.
- Frosts and degree days: Finner’s daily readings from Met Éireann (clidata.met.ie), 2011–2020, averaged by month: a month counts when 27 or more of its days were read (rain and sunshine: every day), and a figure needs 10 such years.
- Then and now: Met Éireann’s 1981–2010 averages on the same 1 km grid, at the same point.
- Altitudes: the town’s ground from the Copernicus GLO-30 surface model (a few metres high in built-up places), the station’s from Met Éireann.
- Comparisons: every Irish town and city neighbourhood of 2,500 or more, read the same way; the five city totals are left out.
- Not on this page: sunshine at this station, snow and wind. Met Éireann publishes none of them on a grid; the frosts here are its nearest station’s, not the town’s own.

The warmest month is July, when afternoons average 18.0°C.
How cold does Mullaghmore get in winter?
February nights average 3.1°C, the coldest of the year. Met Éireann counts frosts only at its weather stations, so there is no frost count for the town itself.

How sunny is it?
Met Éireann publishes its 1991–2020 sunshine averages for its weather stations only, not on the 1 km grid this page reads, so there is no sunshine figure for Mullaghmore itself. Its nearest synoptic station is Finner.
Are these figures for Mullaghmore itself?
Partly. The temperatures and rain are Met Éireann’s 1991–2020 averages on its 1 km grid, read at Mullaghmore’s population centre; the frosts, degree days and year-to-year swings are those of Finner, 14 km east, the nearest of its synoptic stations.
Where do these figures come from?
Met Éireann’s 1991–2020 climate averages, published as maps of Ireland in 1 km squares (Climatological Notes 22 and 23); the page reads the square at Mullaghmore’s population centre. They are 30-year averages, not a forecast.
