Where Doirí Beaga’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 Doirí Beaga’s population centre (0.4 km away).
- Weather station: the nearest of Met Éireann’s 25 synoptic stations, Finner, 65 km south, from Met Éireann’s station list.
- Frosts and degree days: Finner’s daily readings, 2011–2020, 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.
