Each chart shows one value per year; the dot marks the record year. TXx is the hottest daily maximum, TNn the coldest daily minimum, Rx1day and Rx5day the largest one-day and five-day rain totals, and CDD the longest run of days with less than 1 mm of rain. A year with missing days can understate an extreme.
Frost Dates and Growing Season
45 years with a frostAcross 45 years with a frost, the median last spring frost at Ballyshannon (Cathleens Fall) falls on 4 April and the median first autumn frost on 21 November, which leaves a median of 227 days between them.
Fitted over all years, the growing season changes by +2.3 days per decade at this station.
| Measure | Median, all years | Earliest period | Recent period (1988 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 4 April | n/a | 4 April | n/a | 0.0 days per decade |
| First autumn frost | 21 November | n/a | 21 November | n/a | +2.2 days per decade |
| Growing days | 227 days | n/a | 237 days | n/a | +2.3 days per decade |
A frost day is a day with a daily minimum at or below 0 C (32 F). The last spring frost and the first autumn frost are the last and first such days of the cold season, and growing days are the days between them. A negative trend for the last spring frost means it comes earlier.
Rainfall Return Levels
72 years, 1947 to 2025A day with at least 32.1 mm (1.3 in) of rain is expected about once in 2 years. A day with at least 69.6 mm (2.7 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 32.1 mm (1.3 in) | |
| 5 years | 40.6 mm (1.6 in) | |
| 10 years | 46.8 mm (1.8 in) | |
| 25 years | 55.3 mm (2.2 in) | |
| 50 years | 62.2 mm (2.4 in) | |
| 100 years | 69.6 mm (2.7 in) | Longer than the 72 years of record |
The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 72 years of values from 1947 to 2025.
A return level is an estimate. It is least reliable for the long periods, 50 and 100 years, and for any period longer than the record behind the fit, where the fit has to reach past the largest day actually observed. It is not a forecast.
The largest wettest-day totals in the fit: 69.0 mm (2.7 in) in 1995; 62.2 mm (2.4 in) in 1970; 60.3 mm (2.4 in) in 1965.

No change in the annual mean temperature of this station was found against its neighbours.
Climate Twins
2007 to 2025 against 1961 to 1990Over 2007 to 2025, Ballyshannon (Cathleens Fall) had a mean temperature of 10.4 C (50.8 F) and 1,277.3 mm (50.3 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Las Truchas (Mexico, 8,322 km away), Vascogil (Mexico, 8,260 km away) and Valentia Observatory (Ireland, 316 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Las Truchas | Mexico | 8,322 km (5,171 mi) | 10.7 C (51.3 F) | 1,241.0 mm (48.9 in) | 0.63 |
| Vascogil | Mexico | 8,260 km (5,133 mi) | 11.1 C (51.9 F) | 1,364.0 mm (53.7 in) | 0.86 |
| Valentia Observatory | Ireland | 316 km (196 mi) | 10.5 C (50.9 F) | 1,430.2 mm (56.3 in) | 0.88 |
Twins are stations, not cities. A twin is one of the three stations at least 100 km away whose earlier climate is closest to this station's recent one, so a close match does not mean the two places look alike in other ways. A station move or a gap in a record can change that station's averages. The list describes past climate; it is not a forecast and does not say what caused any change. How twins are found, and a search for any station.
