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

65 years, 1924 to 1996

A day with at least 56.6 mm (2.2 in) of rain is expected about once in 2 years. A day with at least 138.0 mm (5.4 in) of rain is expected about once in 100 years.

Rainfall return levels at Santander Centro: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	56.6 mm (2.2 in)
5 years	74.3 mm (2.9 in)
10 years	87.5 mm (3.4 in)
25 years	106.1 mm (4.2 in)
50 years	121.4 mm (4.8 in)
100 years	138.0 mm (5.4 in)	Longer than the 65 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, 65 years of values from 1924 to 1996.

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: 145.0 mm (5.7 in) in 1952; 121.9 mm (4.8 in) in 1980; 107.4 mm (4.2 in) in 1977.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Santander Centro, at 1969 and 1988. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1969 ran 0.3 C (0.5 F) higher than in the years before (likely change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 1988 ran 0.2 C (0.4 F) higher than in the years before (possible change).

Suspected changes in the annual mean temperature at Santander Centro, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1969	+0.3	+0.5	likely	5
1988	+0.2	+0.4	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.
