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.

Across 77 years with a frost, the median last spring frost at Sulak falls on 21 June and the median first autumn frost on 19 August, which leaves a median of 58 days between them.

In 1986 to 2018 the median growing season was 86 days. That is 42 days more than in 1932 to 1967.

Fitted over all years, the growing season changes by +4.7 days per decade at this station.

Frost dates and growing season at Sulak
Measure	Median, all years	Earliest period (1932 to 1967)	Recent period (1986 to 2018)	Recent against earliest	Fitted trend
Last spring frost	21 June	21 June	19 June	2 days earlier	-0.7 days per decade
First autumn frost	19 August	30 July	5 September	37 days later	+3.9 days per decade
Growing days	58 days	44 days	86 days	42 days more	+4.7 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

86 years, 1932 to 2018

A day with at least 50.4 mm (2.0 in) of rain is expected about once in 2 years. A day with at least 122.3 mm (4.8 in) of rain is expected about once in 100 years.

Rainfall return levels at Sulak: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	50.4 mm (2.0 in)
5 years	66.6 mm (2.6 in)
10 years	78.4 mm (3.1 in)
25 years	94.7 mm (3.7 in)
50 years	108.0 mm (4.3 in)
100 years	122.3 mm (4.8 in)	Longer than the 86 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, 86 years of values from 1932 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: 131.4 mm (5.2 in) in 1970; 128.6 mm (5.1 in) in 1984; 105.7 mm (4.2 in) in 1942.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Sulak, at 1999. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1999 ran 0.4 C (0.6 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

2002 to 2018 against 1961 to 1990

Over 2002 to 2018, Sulak had a mean temperature of 0.9 C (33.6 F) and 993.2 mm (39.1 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Wolf Creek Pass 1 E (United States, 10,723 km away), Cape Newenham (United States, 8,479 km away) and Petropavlovskij Majak (Russia, 7,611 km away).

Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Wolf Creek Pass 1 E	United States	10,723 km (6,663 mi)	0.9 C (33.6 F)	1,059.8 mm (41.7 in)	0.75
Cape Newenham	United States	8,479 km (5,269 mi)	0.7 C (33.2 F)	855.9 mm (33.7 in)	0.97
Petropavlovskij Majak	Russia	7,611 km (4,729 mi)	1.4 C (34.5 F)	887.7 mm (34.9 in)	1.02

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.
