Where Askeaton’s numbers come from

Averages over 30 years, not a forecast: the town’s own from Met Éireann’s grid, the frosts, sunshine 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 Askeaton’s population centre (0.5 km away).
  • Weather station: the nearest of Met Éireann’s 25 synoptic stations, Shannon Airport, 11 km north, from Met Éireann’s station list.
  • Frosts, sunshine, degree days: Shannon Airport’s daily readings from Met Éireann (clidata.met.ie), 1991–2020, 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: snow and wind. Met Éireann publishes neither on a grid; the frosts and sunshine here are its nearest station’s, not the town’s own.
