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

65 years with a frost

Across 65 years with a frost, the median last spring frost at Uglegorsk falls on 9 May and the median first autumn frost on 19 October, which leaves a median of 163 days between them.

In 1989 to 2018 the median growing season was 170 days. That is 12 days more than in 1939 to 1981.

Fitted over all years, the growing season changes by +2.1 days per decade at this station.

Frost dates and growing season at Uglegorsk
Measure	Median, all years	Earliest period (1939 to 1981)	Recent period (1989 to 2018)	Recent against earliest	Fitted trend
Last spring frost	9 May	12 May	8 May	4 days earlier	-0.9 days per decade
First autumn frost	19 October	17 October	21 October	4 days later	+1.2 days per decade
Growing days	163 days	158 days	170 days	12 days more	+2.1 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

73 years, 1939 to 2018

A day with at least 39.9 mm (1.6 in) of rain is expected about once in 2 years. A day with at least 109.1 mm (4.3 in) of rain is expected about once in 100 years.

Rainfall return levels at Uglegorsk: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	39.9 mm (1.6 in)
5 years	54.2 mm (2.1 in)
10 years	65.1 mm (2.6 in)
25 years	80.9 mm (3.2 in)
50 years	94.3 mm (3.7 in)
100 years	109.1 mm (4.3 in)	Longer than the 73 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, 73 years of values from 1939 to 2018.

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: 136.5 mm (5.4 in) in 1981; 94.5 mm (3.7 in) in 1956; 85.1 mm (3.4 in) in 1975.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Uglegorsk, at 1959. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1959 ran 0.4 C (0.6 F) higher than in the years before (likely change).

Year	Shift (C)	Shift (F)	Strength	Neighbours
1959	+0.4	+0.6	likely	5

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

2004 to 2018 against 1961 to 1990

Over 2004 to 2018, Uglegorsk had a mean temperature of 3.5 C (38.3 F) and 672.3 mm (26.5 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Grand Marais (United States, 8,131 km away), Ternej (Russia, 611 km away) and Rudnaja Pristan (Russia, 698 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.
