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

88 years with a frost

Across 88 years with a frost, the median last spring frost at Agassiz Cda falls on 13 April and the median first autumn frost on 6 November, which leaves a median of 204 days between them.

In 1954 to 1983 the median growing season was 216 days. That is 35 days more than in 1892 to 1925.

Fitted over all years, the growing season changes by +5.2 days per decade at this station.

Frost dates and growing season at Agassiz Cda
Measure	Median, all years	Earliest period (1892 to 1925)	Recent period (1954 to 1983)	Recent against earliest	Fitted trend
Last spring frost	13 April	28 April	10 April	18 days earlier	-2.6 days per decade
First autumn frost	6 November	20 October	8 November	19 days later	+2.6 days per decade
Growing days	204 days	181 days	216 days	35 days more	+5.2 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

94 years, 1890 to 1983

A day with at least 60.8 mm (2.4 in) of rain is expected about once in 2 years. A day with at least 116.9 mm (4.6 in) of rain is expected about once in 100 years.

Rainfall return levels at Agassiz Cda: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	60.8 mm (2.4 in)
5 years	78.0 mm (3.1 in)
10 years	88.5 mm (3.5 in)
25 years	100.7 mm (4.0 in)
50 years	109.1 mm (4.3 in)
100 years	116.9 mm (4.6 in)	Longer than the 94 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, 94 years of values from 1890 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: 115.8 mm (4.6 in) in 1951; 99.6 mm (3.9 in) in 1909; 99.1 mm (3.9 in) in 1956.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Agassiz Cda, at 1950. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1950 ran 0.2 C (0.3 F) lower than in the years before (possible change).

Year	Shift (C)	Shift (F)	Strength	Neighbours
1950	-0.2	-0.3	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.
