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

31 years with a frost

Across 31 years with a frost, the median last spring frost at El Tejocote falls on 17 March and the median first autumn frost on 31 October, which leaves a median of 224 days between them.

Fitted over all years, the growing season changes by -7.4 days per decade at this station.

Frost dates and growing season at El Tejocote
Measure	Median, all years	Earliest period	Recent period (1971 to 2009)	Recent against earliest	Fitted trend
Last spring frost	17 March	n/a	18 March	n/a	+3.5 days per decade
First autumn frost	31 October	n/a	30 October	n/a	-3.8 days per decade
Growing days	224 days	n/a	224 days	n/a	-7.4 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

38 years, 1969 to 2009

A day with at least 47.2 mm (1.9 in) of rain is expected about once in 2 years. A day with at least 94.3 mm (3.7 in) of rain is expected about once in 100 years.

Rainfall return levels at El Tejocote: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	47.2 mm (1.9 in)
5 years	60.2 mm (2.4 in)
10 years	68.7 mm (2.7 in)
25 years	79.2 mm (3.1 in)
50 years	86.8 mm (3.4 in)	Longer than the 38 years of record
100 years	94.3 mm (3.7 in)	Longer than the 38 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, 38 years of values from 1969 to 2009.

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: 98.8 mm (3.9 in) in 2008; 77.2 mm (3.0 in) in 1976; 73.7 mm (2.9 in) in 2001.
