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

66 years with a frost

Across 66 years with a frost, the median last spring frost at Kapuskasing Cda falls on 13 June and the median first autumn frost on 8 September, which leaves a median of 89 days between them.

In 1954 to 1983 the median growing season was 88 days. That is 2 days fewer than in 1918 to 1947.

Fitted over all years, the growing season changes by +2.7 days per decade at this station.

Frost dates and growing season at Kapuskasing Cda
Measure	Median, all years	Earliest period (1918 to 1947)	Recent period (1954 to 1983)	Recent against earliest	Fitted trend
Last spring frost	13 June	14 June	12 June	2 days earlier	-0.8 days per decade
First autumn frost	8 September	7 September	8 September	1 day later	+1.9 days per decade
Growing days	89 days	90 days	88 days	2 days fewer	+2.7 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

65 years, 1919 to 1983

A day with at least 41.7 mm (1.6 in) of rain is expected about once in 2 years. A day with at least 87.7 mm (3.5 in) of rain is expected about once in 100 years.

Rainfall return levels at Kapuskasing 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	41.7 mm (1.6 in)
5 years	53.5 mm (2.1 in)
10 years	61.4 mm (2.4 in)
25 years	71.8 mm (2.8 in)
50 years	79.7 mm (3.1 in)
100 years	87.7 mm (3.5 in)	Longer than the 65 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, 65 years of values from 1919 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: 80.5 mm (3.2 in) in 1963; 77.0 mm (3.0 in) in 1962; 77.0 mm (3.0 in) in 1969.
