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

68 years with a frost

Across 68 years with a frost, the median last spring frost at Kamloops falls on 26 April and the median first autumn frost on 7 October, which leaves a median of 163 days between them.

In 1935 to 1978 the median growing season was 161 days. That is 1 day fewer than in 1897 to 1926.

Fitted over all years, the growing season changes by -0.1 days per decade at this station.

Frost dates and growing season at Kamloops
Measure	Median, all years	Earliest period (1897 to 1926)	Recent period (1935 to 1978)	Recent against earliest	Fitted trend
Last spring frost	26 April	28 April	28 April	no change	-0.3 days per decade
First autumn frost	7 October	5 October	6 October	1 day later	-0.4 days per decade
Growing days	163 days	162 days	161 days	1 day fewer	-0.1 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

75 years, 1878 to 1980

A day with at least 19.5 mm (0.8 in) of rain is expected about once in 2 years. A day with at least 42.6 mm (1.7 in) of rain is expected about once in 100 years.

Rainfall return levels at Kamloops: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	19.5 mm (0.8 in)
5 years	25.5 mm (1.0 in)
10 years	29.5 mm (1.2 in)
25 years	34.8 mm (1.4 in)
50 years	38.7 mm (1.5 in)
100 years	42.6 mm (1.7 in)	Longer than the 75 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, 75 years of values from 1878 to 1980.

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: 45.7 mm (1.8 in) in 1976; 41.1 mm (1.6 in) in 1917; 33.5 mm (1.3 in) in 1905.
