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

75 years with a frost

Across 75 years with a frost, the median last spring frost at Rostov-Na-Donu falls on 4 April and the median first autumn frost on 18 October, which leaves a median of 193 days between them.

In 1984 to 2018 the median growing season was 200 days. That is 14 days more than in 1936 to 1968.

Fitted over all years, the growing season changes by +3.2 days per decade at this station.

Frost dates and growing season at Rostov-Na-Donu
Measure	Median, all years	Earliest period (1936 to 1968)	Recent period (1984 to 2018)	Recent against earliest	Fitted trend
Last spring frost	4 April	14 April	1 April	13 days earlier	-1.6 days per decade
First autumn frost	18 October	14 October	21 October	7 days later	+1.6 days per decade
Growing days	193 days	186 days	200 days	14 days more	+3.2 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

76 years, 1936 to 2018

A day with at least 34.5 mm (1.4 in) of rain is expected about once in 2 years. A day with at least 75.7 mm (3.0 in) of rain is expected about once in 100 years.

Rainfall return levels at Rostov-Na-Donu: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	34.5 mm (1.4 in)
5 years	45.1 mm (1.8 in)
10 years	52.3 mm (2.1 in)
25 years	61.6 mm (2.4 in)
50 years	68.6 mm (2.7 in)
100 years	75.7 mm (3.0 in)	Longer than the 76 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, 76 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: 75.6 mm (3.0 in) in 2018; 75.0 mm (3.0 in) in 1958; 60.5 mm (2.4 in) in 1953.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1959 ran 0.3 C (0.6 F) higher than in the years before (likely change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 1996 ran 0.6 C (1.1 F) lower than in the years before (likely change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 2005 ran 0.2 C (0.3 F) higher than in the years before (possible change).

Suspected changes in the annual mean temperature at Rostov-Na-Donu, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1959	+0.3	+0.6	likely	5
1996	-0.6	-1.1	likely	5
2005	+0.2	+0.3	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

2004 to 2018 against 1961 to 1990

Over 2004 to 2018, Rostov-Na-Donu had a mean temperature of 11.2 C (52.1 F) and 602.1 mm (23.7 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Groznyj (Russia, 631 km away), Kirwin Dam (United States, 9,532 km away) and Budennovsk (Russia, 428 km away).

Climate twins of Rostov-Na-Donu: stations whose 1961 to 1990 climate is closest to its 2004 to 2018 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Groznyj	Russia	631 km (392 mi)	11.2 C (52.1 F)	438.6 mm (17.3 in)	0.94
Kirwin Dam	United States	9,532 km (5,923 mi)	11.1 C (51.9 F)	584.2 mm (23.0 in)	0.98
Budennovsk	Russia	428 km (266 mi)	10.8 C (51.5 F)	404.6 mm (15.9 in)	1.00

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.
