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 at Ilyinskiy
Measure	Median, all years	Earliest period (1948 to 1981)	Recent period (1992 to 2025)	Recent against earliest	Fitted trend
Last spring frost	19 May	20 May	15 May	5 days earlier	-0.3 days per decade
First autumn frost	8 October	7 October	9 October	2 days later	-0.2 days per decade
Growing days	146 days	140 days	147 days	7 days more	+0.1 days per decade

Expected about once in	A day with at least	Note
2 years	44.5 mm (1.8 in)
5 years	59.4 mm (2.3 in)
10 years	72.0 mm (2.8 in)
25 years	91.8 mm (3.6 in)
50 years	110.0 mm (4.3 in)
100 years	131.7 mm (5.2 in)	Longer than the 71 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, 71 years of values from 1944 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: 161.8 mm (6.4 in) in 2000; 129.4 mm (5.1 in) in 1981; 99.1 mm (3.9 in) in 2022.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Ilyinskiy, at 1959 and 2002. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1959 ran 0.3 C (0.6 F) lower than in the years before (likely change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 2002 ran 0.1 C (0.2 F) lower than in the years before (possible change).

Suspected changes in the annual mean temperature at Ilyinskiy, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1959	-0.3	-0.6	likely	5
2002	-0.1	-0.2	possible	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

2007 to 2025 against 1961 to 1990

Over 2007 to 2025, Ilyinskiy had a mean temperature of 3.4 C (38.0 F) and 759.2 mm (29.9 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Zolotoj (Russia, 254 km away), Uglegorsk (Russia, 120 km away) and Nevelsk (Russia, 150 km away).

Climate twins of Ilyinskiy: stations whose 1961 to 1990 climate is closest to its 2007 to 2025 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Zolotoj	Russia	254 km (158 mi)	2.7 C (36.8 F)	870.3 mm (34.3 in)	1.11
Uglegorsk	Russia	120 km (75 mi)	2.4 C (36.4 F)	693.6 mm (27.3 in)	1.17
Nevelsk	Russia	150 km (93 mi)	4.1 C (39.3 F)	807.4 mm (31.8 in)	1.22

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.
