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

29 years with a frost

Across 29 years with a frost, the median last spring frost at Miquihuana falls on 19 February and the median first autumn frost on 18 November, which leaves a median of 272 days between them.

Fitted over all years, the growing season changes by +2.8 days per decade at this station.

Frost dates and growing season at Miquihuana
Measure	Median, all years	Earliest period	Recent period (1963 to 2011)	Recent against earliest	Fitted trend
Last spring frost	19 February	n/a	19 February	n/a	-3.6 days per decade
First autumn frost	18 November	n/a	18 November	n/a	-0.8 days per decade
Growing days	272 days	n/a	272 days	n/a	+2.8 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

45 years, 1963 to 2011

A day with at least 34.0 mm (1.3 in) of rain is expected about once in 2 years. A day with at least 101.3 mm (4.0 in) of rain is expected about once in 100 years.

Rainfall return levels at Miquihuana: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	34.0 mm (1.3 in)
5 years	47.9 mm (1.9 in)
10 years	58.6 mm (2.3 in)
25 years	74.0 mm (2.9 in)
50 years	86.9 mm (3.4 in)	Longer than the 45 years of record
100 years	101.3 mm (4.0 in)	Longer than the 45 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, 45 years of values from 1963 to 2011.

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: 79.8 mm (3.1 in) in 1977; 79.2 mm (3.1 in) in 1964; 69.9 mm (2.8 in) in 2010.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Miquihuana, at 1982 and 1994. Each is measured against neighbouring stations.

Relative to 4 neighbouring stations, the station's annual mean temperature from 1994 ran 1.6 C (2.9 F) lower than in the years before (likely change).

Suspected changes in the annual mean temperature at Miquihuana, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1982	+1.1	+1.9	likely	4
1994	-1.6	-2.9	likely	4

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.
