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

69 years with a frost

Across 69 years with a frost, the median last spring frost at Kaslo falls on 5 May and the median first autumn frost on 4 October, which leaves a median of 151 days between them.

In 1953 to 1983 the median growing season was 151 days. That is 7 days fewer than in 1896 to 1943.

Fitted over all years, the growing season changes by -2.2 days per decade at this station.

Frost dates and growing season at Kaslo
Measure	Median, all years	Earliest period (1896 to 1943)	Recent period (1953 to 1983)	Recent against earliest	Fitted trend
Last spring frost	5 May	5 May	6 May	1 day later	+0.8 days per decade
First autumn frost	4 October	8 October	4 October	4 days earlier	-1.4 days per decade
Growing days	151 days	158 days	151 days	7 days fewer	-2.2 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

71 years, 1896 to 1983

A day with at least 32.5 mm (1.3 in) of rain is expected about once in 2 years. A day with at least 59.6 mm (2.3 in) of rain is expected about once in 100 years.

Rainfall return levels at Kaslo: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	32.5 mm (1.3 in)
5 years	40.1 mm (1.6 in)
10 years	45.0 mm (1.8 in)
25 years	51.0 mm (2.0 in)
50 years	55.4 mm (2.2 in)
100 years	59.6 mm (2.3 in)	Longer than the 71 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, 71 years of values from 1896 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: 66.0 mm (2.6 in) in 1980; 59.4 mm (2.3 in) in 1971; 50.8 mm (2.0 in) in 1917.
