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 Villagran (Smn) falls on 8 February and the median first autumn frost on 13 December, which leaves a median of 303 days between them.

Frost dates and growing season at Villagran (Smn)
Measure	Median, all years	Earliest period	Recent period (1947 to 1997)	Recent against earliest	Fitted trend
Last spring frost	8 February	n/a	8 February	n/a	n/a
First autumn frost	13 December	n/a	13 December	n/a	n/a
Growing days	303 days	n/a	303 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

51 years, 1943 to 2002

A day with at least 99.0 mm (3.9 in) of rain is expected about once in 2 years. A day with at least 290.3 mm (11.4 in) of rain is expected about once in 100 years.

Rainfall return levels at Villagran (Smn): the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	99.0 mm (3.9 in)
5 years	135.4 mm (5.3 in)
10 years	164.5 mm (6.5 in)
25 years	208.2 mm (8.2 in)
50 years	246.4 mm (9.7 in)
100 years	290.3 mm (11.4 in)	Longer than the 51 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, 51 years of values from 1943 to 2002.

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: 309.9 mm (12.2 in) in 1986; 229.9 mm (9.1 in) in 1975; 209.8 mm (8.3 in) in 1948.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Villagran (Smn), at 1990. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1990 ran 0.6 C (1.0 F) lower than in the years before (likely change).

Year	Shift (C)	Shift (F)	Strength	Neighbours
1990	-0.6	-1.0	likely	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.
