Where Tullaghan’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 Tullaghan’s population centre (0.5 km away).
- Weather station: the nearest of Met Éireann’s 25 synoptic stations, Finner, 6.4 km north-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.

Partly. The temperatures and rain are Met Éireann’s 1991–2020 averages on its 1 km grid, read at Tullaghan’s population centre; the frosts, degree days and year-to-year swings are those of Finner, 6.4 km north-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 Tullaghan’s population centre. They are 30-year averages, not a forecast.
