How Dunshaughlin 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 Meath.
Warmer than it used to be
Dunshaughlin’s 1991–2020 average is 0.2°C warmer than 1981–2010’s. The biggest change is in February (+0.3°C).
A year’s rain is 874 mm, up 2% from 858 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 Dunshaughlin’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 Dunshaughlin’s population centre (0.5 km away).
- Weather station: the nearest of Met Éireann’s 25 synoptic stations, Dunsany, 7.8 km west, from Met Éireann’s station list.
- Frosts and degree days: Dunsany’s daily readings from Met Éireann (clidata.met.ie), 2006–2020, 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.

Are these figures for Dunshaughlin itself?
Partly. The temperatures and rain are Met Éireann’s 1991–2020 averages on its 1 km grid, read at Dunshaughlin’s population centre; the frosts, degree days and year-to-year swings are those of Dunsany, 7.8 km west, 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 Dunshaughlin’s population centre. They are 30-year averages, not a forecast.
