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

63 years with a frost

Across 63 years with a frost, the median last spring frost at Wetaskiwin falls on 28 May and the median first autumn frost on 7 September, which leaves a median of 104 days between them.

In 1945 to 1974 the median growing season was 114 days. That is 20 days more than in 1903 to 1941.

Fitted over all years, the growing season changes by +5.0 days per decade at this station.

Frost dates and growing season at Wetaskiwin
Measure	Median, all years	Earliest period (1903 to 1941)	Recent period (1945 to 1974)	Recent against earliest	Fitted trend
Last spring frost	28 May	3 June	22 May	12 days earlier	-2.4 days per decade
First autumn frost	7 September	3 September	14 September	11 days later	+2.7 days per decade
Growing days	104 days	94 days	114 days	20 days more	+5.0 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

66 years, 1903 to 1974

A day with at least 35.5 mm (1.4 in) of rain is expected about once in 2 years. A day with at least 90.8 mm (3.6 in) of rain is expected about once in 100 years.

Rainfall return levels at Wetaskiwin: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	35.5 mm (1.4 in)
5 years	47.5 mm (1.9 in)
10 years	56.5 mm (2.2 in)
25 years	69.1 mm (2.7 in)
50 years	79.5 mm (3.1 in)
100 years	90.8 mm (3.6 in)	Longer than the 66 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, 66 years of values from 1903 to 1974.

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: 77.7 mm (3.1 in) in 1970; 74.9 mm (2.9 in) in 1974; 70.1 mm (2.8 in) in 1931.

Station Changes

3 suspected

3 changes were suspected in the annual mean temperature of Wetaskiwin, at 1930, 1953 and 1964. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1930 ran 0.5 C (0.9 F) higher than in the years before (possible change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 1953 ran 0.3 C (0.5 F) lower than in the years before (likely change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 1964 ran 0.2 C (0.4 F) higher than in the years before (likely change).

Suspected changes in the annual mean temperature at Wetaskiwin, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1930	+0.5	+0.9	possible	5
1953	-0.3	-0.5	likely	5
1964	+0.2	+0.4	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.
