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
68 years with a frostAcross 68 years with a frost, the median last spring frost at Sundsvalls Flygplats falls on 20 May and the median first autumn frost on 24 September, which leaves a median of 128 days between them.
In 1996 to 2025 the median growing season was 137 days. That is 14 days more than in 1957 to 1987.
Fitted over all years, the growing season changes by +2.6 days per decade at this station.
| Measure | Median, all years | Earliest period (1957 to 1987) | Recent period (1996 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 20 May | 23 May | 18 May | 5 days earlier | -1.1 days per decade |
| First autumn frost | 24 September | 21 September | 30 September | 9 days later | +1.5 days per decade |
| Growing days | 128 days | 123 days | 137 days | 14 days more | +2.6 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
49 years, 1957 to 2005A day with at least 31.9 mm (1.3 in) of rain is expected about once in 2 years. A day with at least 69.2 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 | 31.9 mm (1.3 in) | |
| 5 years | 40.7 mm (1.6 in) | |
| 10 years | 46.9 mm (1.8 in) | |
| 25 years | 55.4 mm (2.2 in) | |
| 50 years | 62.1 mm (2.4 in) | Longer than the 49 years of record |
| 100 years | 69.2 mm (2.7 in) | Longer than the 49 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, 49 years of values from 1957 to 2005.
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: 66.9 mm (2.6 in) in 1959; 65.9 mm (2.6 in) in 1969; 62.1 mm (2.4 in) in 2001.
