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 Derbent
Measure	Median, all years	Earliest period (1936 to 1972)	Recent period (1985 to 2017)	Recent against earliest	Fitted trend
Last spring frost	18 March	20 March	12 March	8 days earlier	-2.2 days per decade
First autumn frost	1 December	3 December	2 December	1 day earlier	-0.3 days per decade
Growing days	259 days	258 days	266 days	8 days more	+1.9 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

82 years, 1936 to 2018

A day with at least 35.1 mm (1.4 in) of rain is expected about once in 2 years. A day with at least 113.3 mm (4.5 in) of rain is expected about once in 100 years.

Rainfall return levels at Derbent: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	35.1 mm (1.4 in)
5 years	52.3 mm (2.1 in)
10 years	65.0 mm (2.6 in)
25 years	82.9 mm (3.3 in)
50 years	97.5 mm (3.8 in)
100 years	113.3 mm (4.5 in)	Longer than the 82 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, 82 years of values from 1936 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: 113.2 mm (4.5 in) in 1939; 110.5 mm (4.4 in) in 1999; 91.6 mm (3.6 in) in 2000.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Derbent, at 1980 and 2002. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1980 ran 0.2 C (0.3 F) higher than in the years before (possible change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 2002 ran 0.2 C (0.4 F) higher than in the years before (likely change).

Suspected changes in the annual mean temperature at Derbent, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1980	+0.2	+0.3	possible	5
2002	+0.2	+0.4	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

2003 to 2018 against 1961 to 1990

Over 2003 to 2018, Derbent had a mean temperature of 14.3 C (57.8 F) and 406.4 mm (16.0 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Ganca (Azerbaijan, 218 km away), Tbilisi (Georgia, 281 km away) and Newkirk (United States, 10,994 km away).

Climate twins of Derbent: stations whose 1961 to 1990 climate is closest to its 2003 to 2018 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Ganca	Azerbaijan	218 km (135 mi)	14.0 C (57.3 F)	278.6 mm (11.0 in)	1.30
Tbilisi	Georgia	281 km (175 mi)	13.7 C (56.7 F)	492.5 mm (19.4 in)	1.48
Newkirk	United States	10,994 km (6,831 mi)	14.2 C (57.5 F)	376.4 mm (14.8 in)	1.64

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.
