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 Olds falls on 28 May and the median first autumn frost on 11 September, which leaves a median of 108 days between them.

In 1953 to 1983 the median growing season was 114 days. That is 15 days more than in 1916 to 1949.

Fitted over all years, the growing season changes by +4.6 days per decade at this station.

Frost dates and growing season at Olds
Measure	Median, all years	Earliest period (1916 to 1949)	Recent period (1953 to 1983)	Recent against earliest	Fitted trend
Last spring frost	28 May	31 May	21 May	10 days earlier	-2.6 days per decade
First autumn frost	11 September	11 September	11 September	no change	+2.0 days per decade
Growing days	108 days	99 days	114 days	15 days more	+4.6 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

61 years, 1916 to 1983

A day with at least 37.5 mm (1.5 in) of rain is expected about once in 2 years. A day with at least 111.6 mm (4.4 in) of rain is expected about once in 100 years.

Rainfall return levels at Olds: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	37.5 mm (1.5 in)
5 years	53.4 mm (2.1 in)
10 years	65.4 mm (2.6 in)
25 years	82.3 mm (3.2 in)
50 years	96.3 mm (3.8 in)
100 years	111.6 mm (4.4 in)	Longer than the 61 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, 61 years of values from 1916 to 1983.

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: 104.1 mm (4.1 in) in 1916; 87.0 mm (3.4 in) in 1978; 83.6 mm (3.3 in) in 1966.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Olds, at 1935 and 1958. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1935 ran 0.4 C (0.8 F) higher than in the years before (likely change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 1958 ran 0.3 C (0.5 F) lower than in the years before (likely change).

Suspected changes in the annual mean temperature at Olds, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1935	+0.4	+0.8	likely	5
1958	-0.3	-0.5	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.
