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.
Rainfall Return Levels
66 years, 1960 to 2025A day with at least 32.9 mm (1.3 in) of rain is expected about once in 2 years. A day with at least 85.2 mm (3.4 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 32.9 mm (1.3 in) | |
| 5 years | 43.7 mm (1.7 in) | |
| 10 years | 52.0 mm (2.0 in) | |
| 25 years | 64.0 mm (2.5 in) | |
| 50 years | 74.0 mm (2.9 in) | |
| 100 years | 85.2 mm (3.4 in) | Longer than the 66 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, 66 years of values from 1960 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: 119.4 mm (4.7 in) in 1960; 62.5 mm (2.5 in) in 2004; 59.1 mm (2.3 in) in 2014.
Station Changes
No change in the annual mean temperature of this station was found against its neighbours.
Climate Twins
2011 to 2025 against 1961 to 1990Over 2011 to 2025, Guernsey: Airport had a mean temperature of 12.1 C (53.7 F) and 866.9 mm (34.1 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Belle Ile - le Talut (France, 242 km away), Oviedo (Spain, 721 km away) and Brest-Guipavas (France, 172 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Belle Ile - le Talut | France | 242 km (150 mi) | 12.1 C (53.8 F) | 685.0 mm (27.0 in) | 0.78 |
| Oviedo | Spain | 721 km (448 mi) | 12.8 C (55.0 F) | 968.9 mm (38.1 in) | 0.99 |
| Brest-Guipavas | France | 172 km (107 mi) | 10.9 C (51.7 F) | 1,110.5 mm (43.7 in) | 1.52 |
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.
