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
59 years with a frostAcross 59 years with a frost, the median last spring frost at Storfinnforsen falls on 25 May and the median first autumn frost on 17 September, which leaves a median of 113 days between them.
Fitted over all years, the growing season changes by +4.7 days per decade at this station.
| Measure | Median, all years | Earliest period | Recent period (1987 to 2017) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 25 May | n/a | 23 May | n/a | -2.0 days per decade |
| First autumn frost | 17 September | n/a | 23 September | n/a | +2.7 days per decade |
| Growing days | 113 days | n/a | 120 days | n/a | +4.7 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
61 years, 1957 to 2017A day with at least 32.3 mm (1.3 in) of rain is expected about once in 2 years. A day with at least 68.8 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 | 32.3 mm (1.3 in) | |
| 5 years | 42.0 mm (1.7 in) | |
| 10 years | 48.5 mm (1.9 in) | |
| 25 years | 56.6 mm (2.2 in) | |
| 50 years | 62.7 mm (2.5 in) | |
| 100 years | 68.8 mm (2.7 in) | Longer than the 61 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, 61 years of values from 1957 to 2017.
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: 67.0 mm (2.6 in) in 2009; 56.9 mm (2.2 in) in 1972; 55.5 mm (2.2 in) in 2013.

No change in the annual mean temperature of this station was found against its neighbours.
Climate Twins
2002 to 2017 against 1961 to 1990Over 2002 to 2017, Storfinnforsen had a mean temperature of 3.5 C (38.3 F) and 583.5 mm (23.0 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Delsbo (Sweden, 202 km away), Edsbyn (Sweden, 247 km away) and Mockfjard (Sweden, 349 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Delsbo | Sweden | 202 km (126 mi) | 3.7 C (38.7 F) | 609.9 mm (24.0 in) | 0.58 |
| Edsbyn | Sweden | 247 km (153 mi) | 3.7 C (38.7 F) | 579.1 mm (22.8 in) | 0.70 |
| Mockfjard | Sweden | 349 km (217 mi) | 3.8 C (38.8 F) | 630.1 mm (24.8 in) | 0.79 |
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.
