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

65 years with a frost

Across 65 years with a frost, the median last spring frost at Lulea-Bergnaset falls on 26 May and the median first autumn frost on 7 September, which leaves a median of 105 days between them.

In 1966 to 2014 the median growing season was 114 days. That is 14 days more than in 1930 to 1960.

Fitted over all years, the growing season changes by +3.4 days per decade at this station.

Frost dates and growing season at Lulea-Bergnaset
Measure	Median, all years	Earliest period (1930 to 1960)	Recent period (1966 to 2014)	Recent against earliest	Fitted trend
Last spring frost	26 May	3 June	20 May	14 days earlier	-2.3 days per decade
First autumn frost	7 September	7 September	9 September	2 days later	+1.1 days per decade
Growing days	105 days	100 days	114 days	14 days more	+3.4 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

78 years, 1930 to 2022

A day with at least 27.1 mm (1.1 in) of rain is expected about once in 2 years. A day with at least 77.2 mm (3.0 in) of rain is expected about once in 100 years.

Rainfall return levels at Lulea-Bergnaset: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	27.1 mm (1.1 in)
5 years	35.4 mm (1.4 in)
10 years	42.6 mm (1.7 in)
25 years	53.9 mm (2.1 in)
50 years	64.5 mm (2.5 in)
100 years	77.2 mm (3.0 in)	Longer than the 78 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, 78 years of values from 1930 to 2022.

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: 100.2 mm (3.9 in) in 1960; 76.8 mm (3.0 in) in 1975; 51.5 mm (2.0 in) in 2003.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Lulea-Bergnaset, at 2003. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 2003 ran 0.3 C (0.6 F) higher than in the years before (likely change).

Year	Shift (C)	Shift (F)	Strength	Neighbours
2003	+0.3	+0.6	likely	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.
