How Frenchpark 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 Roscommon.
Warmer than it used to be
Frenchpark’s 1991–2020 average is 0.2°C warmer than 1981–2010’s. The biggest change is in February (+0.4°C).
A year’s rain is 1,202 mm, up 2% from 1,175 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 Frenchpark’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 Frenchpark’s population centre (0.3 km away).
- Weather station: the nearest of Met Éireann’s 25 synoptic stations, Knock Airport, 27 km west, from Met Éireann’s station list.
- Frosts, sunshine, degree days: Knock Airport’s daily readings from Met Éireann (clidata.met.ie), 1996–2020, 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.
