Weather station

Met Éireann’s nearest station: Valentia

Valentia is 49 km south-west of Spa, the nearest of the 25 synoptic stations where Met Éireann records the weather around the clock. The station stands 24 m above sea level; Spa’s centre, 25 m.

The table is Valentia’s own record, averaged over 1991–2020 from its daily readings (ours, not a Met Éireann table). The rest of the page is Met Éireann’s 1 km grid at Spa itself: past 40 km, the station’s frosts and sunshine don’t stand for the town.

Where Spa’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 Spa’s population centre (0.4 km away).
Weather station: the nearest of Met Éireann’s 25 synoptic stations, Valentia, 49 km south-west, from Met Éireann’s station list.
Frosts and degree days: Valentia’s daily readings, 1991–2020, 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.

Questions about Spa’s climate

How warm does Spa get in summer?

July is the warmest month, with average highs of 19.3°C.

How cold does Spa get in winter?

The coldest nights come in February, averaging 4.1°C. Met Éireann counts frosts only at its weather stations, so there is no frost count for the town itself.

How much rain does Spa get?

About 1,225 mm a year, more than 88% of Irish towns. November is the wettest month (148 mm) and May the driest (70 mm).

How sunny is it?

Met Éireann publishes its 1991–2020 sunshine averages for its weather stations only, not on the 1 km grid this page reads, so there is no sunshine figure for Spa itself. Its nearest synoptic station is Valentia.

Are these figures for Spa itself?

Yes: they are Met Éireann’s 1991–2020 averages on its 1 km grid, read at Spa’s population centre. The nearest of its synoptic weather stations, Valentia, is 49 km south-west.

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