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
67 years with a frostAcross 67 years with a frost, the median last spring frost at Fruholmen Fyr falls on 15 May and the median first autumn frost on 18 October, which leaves a median of 154 days between them.
In 1993 to 2025 the median growing season was 165 days. That is 21 days more than in 1955 to 1985.
Fitted over all years, the growing season changes by +4.0 days per decade at this station.
| Measure | Median, all years | Earliest period (1955 to 1985) | Recent period (1993 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 15 May | 21 May | 13 May | 8 days earlier | -2.4 days per decade |
| First autumn frost | 18 October | 14 October | 19 October | 5 days later | +1.7 days per decade |
| Growing days | 154 days | 144 days | 165 days | 21 days more | +4.0 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
48 years, 1955 to 2002A day with at least 24.5 mm (1.0 in) of rain is expected about once in 2 years. A day with at least 45.9 mm (1.8 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 24.5 mm (1.0 in) | |
| 5 years | 30.9 mm (1.2 in) | |
| 10 years | 34.9 mm (1.4 in) | |
| 25 years | 39.5 mm (1.6 in) | |
| 50 years | 42.8 mm (1.7 in) | Longer than the 48 years of record |
| 100 years | 45.9 mm (1.8 in) | Longer than the 48 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, 48 years of values from 1955 to 2002.
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: 47.2 mm (1.9 in) in 1963; 41.5 mm (1.6 in) in 1961; 35.9 mm (1.4 in) in 1959.
Station Changes
1 suspectedOne change was suspected in the annual mean temperature of Fruholmen Fyr, at 2013. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 2013 ran 0.2 C (0.3 F) lower than in the years before (possible change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 2013 | -0.2 | -0.3 | possible | 5 |
Possible change at the station (a move, a new instrument or a new site); the record is kept as measured. A "likely" change has a larger test statistic than a "possible" one. Neither says why the station differs from its neighbours. How changes are found, and the largest ones.
