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

23 years with a frost

Across 23 years with a frost, the median last spring frost at Santiago Zautla (Cfe) falls on 15 February and the median first autumn frost on 18 November, which leaves a median of 283 days between them.

Frost dates and growing season at Santiago Zautla (Cfe)
Measure	Median, all years	Earliest period	Recent period (1961 to 2003)	Recent against earliest	Fitted trend
Last spring frost	15 February	n/a	15 February	n/a	n/a
First autumn frost	18 November	n/a	18 November	n/a	n/a
Growing days	283 days	n/a	283 days	n/a	n/a

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, 1955 to 2008

A day with at least 38.4 mm (1.5 in) of rain is expected about once in 2 years. A day with at least 173.6 mm (6.8 in) of rain is expected about once in 100 years.

Rainfall return levels at Santiago Zautla (Cfe): the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	38.4 mm (1.5 in)
5 years	54.7 mm (2.2 in)
10 years	70.9 mm (2.8 in)
25 years	100.4 mm (4.0 in)
50 years	131.6 mm (5.2 in)	Longer than the 46 years of record
100 years	173.6 mm (6.8 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 1955 to 2008.

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: 159.8 mm (6.3 in) in 1955; 159.8 mm (6.3 in) in 1974; 79.8 mm (3.1 in) in 1956.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Santiago Zautla (Cfe), at 1999. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1999 ran 0.4 C (0.8 F) lower than in the years before (possible change).

Year	Shift (C)	Shift (F)	Strength	Neighbours
1999	-0.4	-0.8	possible	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.
