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

40 years with a frost

Across 40 years with a frost, the median last spring frost at Bacanuchi falls on 12 April and the median first autumn frost on 2 November, which leaves a median of 211 days between them.

Fitted over all years, the growing season changes by -5.6 days per decade at this station.

Frost dates and growing season at Bacanuchi
Measure	Median, all years	Earliest period	Recent period (1976 to 2011)	Recent against earliest	Fitted trend
Last spring frost	12 April	n/a	13 April	n/a	+2.8 days per decade
First autumn frost	2 November	n/a	4 November	n/a	-2.8 days per decade
Growing days	211 days	n/a	210 days	n/a	-5.6 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

46 years, 1964 to 2012

A day with at least 46.3 mm (1.8 in) of rain is expected about once in 2 years. A day with at least 120.3 mm (4.7 in) of rain is expected about once in 100 years.

Rainfall return levels at Bacanuchi: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	46.3 mm (1.8 in)
5 years	61.4 mm (2.4 in)
10 years	73.1 mm (2.9 in)
25 years	90.0 mm (3.5 in)
50 years	104.3 mm (4.1 in)	Longer than the 46 years of record
100 years	120.3 mm (4.7 in)	Longer than the 46 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, 46 years of values from 1964 to 2012.

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: 127.0 mm (5.0 in) in 1994; 90.9 mm (3.6 in) in 2000; 88.9 mm (3.5 in) in 1966.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Bacanuchi, at 1971 and 1989. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1971 ran 0.4 C (0.7 F) lower than in the years before (possible change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 1989 ran 0.3 C (0.6 F) lower than in the years before (likely change).

Suspected changes in the annual mean temperature at Bacanuchi, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1971	-0.4	-0.7	possible	5
1989	-0.3	-0.6	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.
