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

73 years with a frost

Across 73 years with a frost, the median last spring frost at Inza falls on 20 May and the median first autumn frost on 22 September, which leaves a median of 125 days between them.

In 1989 to 2018 the median growing season was 122 days. That is 2 days fewer than in 1936 to 1969.

Fitted over all years, the growing season changes by -0.8 days per decade at this station.

Frost dates and growing season at Inza
Measure	Median, all years	Earliest period (1936 to 1969)	Recent period (1989 to 2018)	Recent against earliest	Fitted trend
Last spring frost	20 May	22 May	21 May	1 day earlier	+0.3 days per decade
First autumn frost	22 September	22 September	20 September	2 days earlier	-0.6 days per decade
Growing days	125 days	124 days	122 days	2 days fewer	-0.8 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

75 years, 1936 to 2018

A day with at least 31.8 mm (1.3 in) of rain is expected about once in 2 years. A day with at least 87.2 mm (3.4 in) of rain is expected about once in 100 years.

Rainfall return levels at Inza: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	31.8 mm (1.3 in)
5 years	44.2 mm (1.7 in)
10 years	53.3 mm (2.1 in)
25 years	65.9 mm (2.6 in)
50 years	76.2 mm (3.0 in)
100 years	87.2 mm (3.4 in)	Longer than the 75 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, 75 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: 84.3 mm (3.3 in) in 1963; 78.8 mm (3.1 in) in 1995; 78.3 mm (3.1 in) in 1952.

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, Inza had a mean temperature of 5.2 C (41.3 F) and 533.3 mm (21.0 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Rjazan (Russia, 431 km away), Zametchino (Russia, 252 km away) and Tambov (Russia, 351 km away).

Climate twins of Inza: 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
Rjazan	Russia	431 km (268 mi)	5.0 C (40.9 F)	551.7 mm (21.7 in)	0.54
Zametchino	Russia	252 km (157 mi)	4.9 C (40.8 F)	505.7 mm (19.9 in)	0.61
Tambov	Russia	351 km (218 mi)	5.6 C (42.0 F)	548.5 mm (21.6 in)	0.64

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.
