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

110 years with a frost

Across 110 years with a frost, the median last spring frost at Vastervik falls on 4 May and the median first autumn frost on 12 October, which leaves a median of 165 days between them.

In 1964 to 1994 the median growing season was 153 days. That is 16 days fewer than in 1882 to 1913.

Fitted over all years, the growing season changes by -2.3 days per decade at this station.

Growing days165 days169 days153 days16 days fewer-2.3 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

135 years, 1860 to 1994

A day with at least 32.2 mm (1.3 in) of rain is expected about once in 2 years. A day with at least 99.6 mm (3.9 in) of rain is expected about once in 100 years.

25 years69.9 mm (2.8 in)
50 years83.6 mm (3.3 in)
100 years99.6 mm (3.9 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 135 years of values from 1860 to 1994.

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: 112.9 mm (4.4 in) in 1937; 92.4 mm (3.6 in) in 1934; 89.6 mm (3.5 in) in 1945.

Station Changes

3 suspected

3 changes were suspected in the annual mean temperature of Vastervik, at 1946, 1955 and 1980. Each is measured against neighbouring stations.

  • Relative to 5 neighbouring stations, the station's annual mean temperature from 1946 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 1955 ran 0.2 C (0.3 F) higher than in the years before (possible change).
  • Relative to 5 neighbouring stations, the station's annual mean temperature from 1980 ran 0.4 C (0.8 F) lower than in the years before (likely 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.
