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

63 years with a frost

Across 63 years with a frost, the median last spring frost at Irtyshsk falls on 12 May and the median first autumn frost on 26 September, which leaves a median of 135 days between them.

In 1978 to 2025 the median growing season was 140 days. That is 14 days more than in 1936 to 1974.

Fitted over all years, the growing season changes by +3.1 days per decade at this station.

First autumn frost26 September23 September29 September6 days later+0.6 days per decade
Growing days135 days126 days140 days14 days more+3.1 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

66 years, 1936 to 2001

A day with at least 26.3 mm (1.0 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.

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 66 years of values from 1936 to 2001.

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: 106.0 mm (4.2 in) in 1993; 63.4 mm (2.5 in) in 1991; 51.7 mm (2.0 in) in 1968.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Irtyshsk, at 1973 and 1997. Each is measured against neighbouring stations.

  • Relative to 4 neighbouring stations, the station's annual mean temperature from 1973 ran 0.4 C (0.8 F) lower than in the years before (likely change).
  • Relative to 4 neighbouring stations, the station's annual mean temperature from 1997 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.
