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

68 years with a frost

Across 68 years with a frost, the median last spring frost at Joskar-Ola falls on 16 May and the median first autumn frost on 23 September, which leaves a median of 128 days between them.

In 1989 to 2018 the median growing season was 131 days. That is 9 days more than in 1936 to 1980.

Fitted over all years, the growing season changes by +2.5 days per decade at this station.

Frost dates and growing season at Joskar-Ola
Measure	Median, all years	Earliest period (1936 to 1980)	Recent period (1989 to 2018)	Recent against earliest	Fitted trend
Last spring frost	16 May	21 May	15 May	6 days earlier	-1.3 days per decade
First autumn frost	23 September	20 September	24 September	4 days later	+1.2 days per decade
Growing days	128 days	122 days	131 days	9 days more	+2.5 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

80 years, 1936 to 2024

A day with at least 29.5 mm (1.2 in) of rain is expected about once in 2 years. A day with at least 70.5 mm (2.8 in) of rain is expected about once in 100 years.

Rainfall return levels at Joskar-Ola: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	29.5 mm (1.2 in)
5 years	38.5 mm (1.5 in)
10 years	45.2 mm (1.8 in)
25 years	54.5 mm (2.1 in)
50 years	62.2 mm (2.4 in)
100 years	70.5 mm (2.8 in)	Longer than the 80 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, 80 years of values from 1936 to 2024.

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: 65.6 mm (2.6 in) in 2000; 57.3 mm (2.3 in) in 1954; 56.6 mm (2.2 in) in 2012.

Climate Twins

2004 to 2018 against 1961 to 1990

Over 2004 to 2018, Joskar-Ola had a mean temperature of 4.8 C (40.6 F) and 586.0 mm (23.1 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Penza (Russia, 428 km away), Zametchino (Russia, 481 km away) and Elatma (Russia, 425 km away).

Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Penza	Russia	428 km (266 mi)	5.0 C (41.0 F)	541.4 mm (21.3 in)	0.55
Zametchino	Russia	481 km (299 mi)	4.9 C (40.8 F)	505.7 mm (19.9 in)	0.64
Elatma	Russia	425 km (264 mi)	4.6 C (40.3 F)	612.7 mm (24.1 in)	0.65

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.
