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

70 years with a frost

Across 70 years with a frost, the median last spring frost at Salmon Arm falls on 5 May and the median first autumn frost on 3 October, which leaves a median of 152 days between them.

In 1952 to 1981 the median growing season was 152 days. That is 1 day fewer than in 1912 to 1941.

Fitted over all years, the growing season changes by +0.6 days per decade at this station.

Frost dates and growing season at Salmon Arm
Measure	Median, all years	Earliest period (1912 to 1941)	Recent period (1952 to 1981)	Recent against earliest	Fitted trend
Last spring frost	5 May	4 May	7 May	3 days later	-0.4 days per decade
First autumn frost	3 October	4 October	3 October	1 day earlier	+0.1 days per decade
Growing days	152 days	153 days	152 days	1 day fewer	+0.6 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

69 years, 1912 to 1981

A day with at least 25.8 mm (1.0 in) of rain is expected about once in 2 years. A day with at least 50.5 mm (2.0 in) of rain is expected about once in 100 years.

Rainfall return levels at Salmon Arm: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	25.8 mm (1.0 in)
5 years	32.9 mm (1.3 in)
10 years	37.4 mm (1.5 in)
25 years	42.8 mm (1.7 in)
50 years	46.7 mm (1.8 in)
100 years	50.5 mm (2.0 in)	Longer than the 69 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, 69 years of values from 1912 to 1981.

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: 49.5 mm (1.9 in) in 1956; 45.7 mm (1.8 in) in 1936; 43.2 mm (1.7 in) in 1951.
