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.

Rainfall Return Levels

46 years, 1960 to 2011

A day with at least 94.2 mm (3.7 in) of rain is expected about once in 2 years. A day with at least 315.7 mm (12.4 in) of rain is expected about once in 100 years.

Rainfall return levels at Tempoal de Sanchez: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	94.2 mm (3.7 in)
5 years	134.1 mm (5.3 in)
10 years	166.9 mm (6.6 in)
25 years	217.4 mm (8.6 in)
50 years	262.8 mm (10.3 in)	Longer than the 46 years of record
100 years	315.7 mm (12.4 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 1960 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: 290.6 mm (11.4 in) in 1990; 243.3 mm (9.6 in) in 1984; 199.9 mm (7.9 in) in 1991.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Tempoal de Sanchez, at 1974. Each is measured against neighbouring stations.

Suspected changes in the annual mean temperature at Tempoal de Sanchez, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1974	-0.4	-0.7	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.
