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

89 years with a frost

Across 89 years with a frost, the median last spring frost at Mahackala falls on 25 March and the median first autumn frost on 16 November, which leaves a median of 235 days between them.

In 1982 to 2012 the median growing season was 227 days. That is 9 days fewer than in 1913 to 1951.

Fitted over all years, the growing season changes by -1.4 days per decade at this station.

Frost dates and growing season at Mahackala
Measure	Median, all years	Earliest period (1913 to 1951)	Recent period (1982 to 2012)	Recent against earliest	Fitted trend
Last spring frost	25 March	26 March	25 March	1 day earlier	-0.1 days per decade
First autumn frost	16 November	22 November	12 November	10 days earlier	-1.5 days per decade
Growing days	235 days	236 days	227 days	9 days fewer	-1.4 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

126 years, 1882 to 2019

A day with at least 32.3 mm (1.3 in) of rain is expected about once in 2 years. A day with at least 96.9 mm (3.8 in) of rain is expected about once in 100 years.

Rainfall return levels at Mahackala: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	32.3 mm (1.3 in)
5 years	46.0 mm (1.8 in)
10 years	56.4 mm (2.2 in)
25 years	71.1 mm (2.8 in)
50 years	83.4 mm (3.3 in)
100 years	96.9 mm (3.8 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 126 years of values from 1882 to 2019.

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: 123.8 mm (4.9 in) in 1995; 103.5 mm (4.1 in) in 1944; 84.4 mm (3.3 in) in 1990.

Station Changes

3 suspected

3 changes were suspected in the annual mean temperature of Mahackala, at 1968, 1987 and 1992. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1968 ran 0.2 C (0.4 F) lower than in the years before (likely change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 1987 ran 0.4 C (0.8 F) higher than in the years before (possible change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 1992 ran 1.0 C (1.9 F) lower than in the years before (likely change).

Suspected changes in the annual mean temperature at Mahackala, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1968	-0.2	-0.4	likely	5
1987	+0.4	+0.8	possible	5
1992	-1.0	-1.9	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.
