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

80 years with a frost

Across 80 years with a frost, the median last spring frost at Bolsoy Santar falls on 23 June and the median first autumn frost on 25 August, which leaves a median of 60 days between them.

In 1991 to 2023 the median growing season was 65 days. That is 19 days more than in 1936 to 1968.

Fitted over all years, the growing season changes by +1.7 days per decade at this station.

First autumn frost25 August7 August26 August19 days later+1.2 days per decade
Growing days60 days46 days65 days19 days more+1.7 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

91 years, 1925 to 2023

A day with at least 40.0 mm (1.6 in) of rain is expected about once in 2 years. A day with at least 98.8 mm (3.9 in) of rain is expected about once in 100 years.

50 years88.4 mm (3.5 in)
100 years98.8 mm (3.9 in)Longer than the 91 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, 91 years of values from 1925 to 2023.

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: 95.3 mm (3.8 in) in 2017; 92.1 mm (3.6 in) in 1981; 81.5 mm (3.2 in) in 1990.

Climate Twins

2007 to 2023 against 1961 to 1990

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.
