How Dunhill 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 and neighbourhoods of 2,500+ in County Waterford.
Warmer than it used to be
Dunhill’s 1991–2020 average is 0.2°C warmer than 1981–2010’s. The biggest change is in January (+0.3°C).
A year’s rain is 1,092 mm, up 2% from 1,072 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 Dunhill’s numbers come from
Averages over 30 years, not a forecast.
- 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 Dunhill’s population centre (0.6 km away).
- Weather station: the nearest of Met Éireann’s 25 synoptic stations, Johnstown Castle, 54 km east, from Met Éireann’s station list.
- Frosts and degree days: Johnstown Castle’s daily readings, 2008–2020, in the station table only: past 40 km they don’t stand for the town.
- 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, frost days, warm days, snow and wind. Met Éireann publishes no 1991–2020 grid for them, only tables for its stations, so no town has a figure of its own.

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 Dunhill’s population centre. They are 30-year averages, not a forecast.
