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

104 years with a frost

Across 104 years with a frost, the median last spring frost at Poretskoye falls on 8 May and the median first autumn frost on 27 September, which leaves a median of 142 days between them.

In 1990 to 2019 the median growing season was 146 days. That is 5 days more than in 1894 to 1942.

Fitted over all years, the growing season changes by +1.0 days per decade at this station.

First autumn frost27 September26 September27 September1 day later+0.4 days per decade
Growing days142 days141 days146 days5 days more+1.0 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

127 years, 1892 to 2024

A day with at least 30.5 mm (1.2 in) of rain is expected about once in 2 years. A day with at least 90.9 mm (3.6 in) of rain is expected about once in 100 years.

25 years65.8 mm (2.6 in)
50 years77.6 mm (3.1 in)
100 years90.9 mm (3.6 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 127 years of values from 1892 to 2024.

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: 107.5 mm (4.2 in) in 1960; 101.0 mm (4.0 in) in 1930; 67.0 mm (2.6 in) in 1899.

Station Changes

3 suspected

3 changes were suspected in the annual mean temperature of Poretskoye, at 1959, 1992 and 2010. Each is measured against neighbouring stations.

  • Relative to 5 neighbouring stations, the station's annual mean temperature from 1959 ran 0.3 C (0.5 F) lower than in the years before (likely change).
  • Relative to 5 neighbouring stations, the station's annual mean temperature from 1992 ran 0.1 C (0.2 F) higher than in the years before (possible change).
  • Relative to 5 neighbouring stations, the station's annual mean temperature from 2010 ran 0.2 C (0.4 F) lower 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.

Climate Twins

2005 to 2019 against 1961 to 1990

Over 2005 to 2019, Poretskoye had a mean temperature of 5.5 C (41.8 F) and 477.1 mm (18.8 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Rostoshi (Russia, 407 km away), Tambov (Russia, 418 km away) and Balashov (Russia, 455 km away).

Twins are stations, not cities. A twin is one of the three stations at least 100 km away whose earlier climate is closest to this station's recent one, so a close match does not mean the two places look alike in other ways. A station move or a gap in a record can change that station's averages. The list describes past climate; it is not a forecast and does not say what caused any change. How twins are found, and a search for any station.
