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

96 years with a frost

Across 96 years with a frost, the median last spring frost at Umea falls on 29 May and the median first autumn frost on 12 September, which leaves a median of 105 days between them.

In 1948 to 1978 the median growing season was 108 days. That is 15 days more than in 1882 to 1911.

Fitted over all years, the growing season changes by +4.2 days per decade at this station.

Frost dates and growing season at Umea
MeasureMedian, all yearsEarliest period (1882 to 1911)Recent period (1948 to 1978)Recent against earliestFitted trend

First autumn frost12 September7 September14 September7 days later+2.9 days per decade
Growing days105 days93 days108 days15 days more+4.2 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

120 years, 1859 to 1978

A day with at least 32.4 mm (1.3 in) of rain is expected about once in 2 years. A day with at least 80.1 mm (3.2 in) of rain is expected about once in 100 years.

2 years32.4 mm (1.3 in)

25 years61.6 mm (2.4 in)
50 years70.5 mm (2.8 in)
100 years80.1 mm (3.2 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 120 years of values from 1859 to 1978.

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: 86.1 mm (3.4 in) in 1864; 81.4 mm (3.2 in) in 1899; 74.5 mm (2.9 in) in 1866.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Umea, at 1958 and 1968. Each is measured against neighbouring stations.

  • Relative to 5 neighbouring stations, the station's annual mean temperature from 1958 ran 0.2 C (0.4 F) higher than in the years before (likely change).
  • Relative to 5 neighbouring stations, the station's annual mean temperature from 1968 ran 0.2 C (0.3 F) higher than in the years before (possible change).

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.
