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

60 years with a frost

Across 60 years with a frost, the median last spring frost at Barrage Gouin falls on 9 June and the median first autumn frost on 10 September, which leaves a median of 93 days between them.

In 1947 to 1980 the median growing season was 94 days. That is 4 days more than in 1915 to 1946.

Fitted over all years, the growing season changes by +4.2 days per decade at this station.

Frost dates and growing season at Barrage Gouin
Measure	Median, all years	Earliest period (1915 to 1946)	Recent period (1947 to 1980)	Recent against earliest	Fitted trend
Last spring frost	9 June	8 June	10 June	2 days later	-0.4 days per decade
First autumn frost	10 September	9 September	12 September	3 days later	+3.8 days per decade
Growing days	93 days	90 days	94 days	4 days more	+4.2 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

63 years, 1914 to 1980

A day with at least 41.1 mm (1.6 in) of rain is expected about once in 2 years. A day with at least 89.2 mm (3.5 in) of rain is expected about once in 100 years.

Rainfall return levels at Barrage Gouin: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	41.1 mm (1.6 in)
5 years	53.7 mm (2.1 in)
10 years	62.2 mm (2.4 in)
25 years	73.0 mm (2.9 in)
50 years	81.1 mm (3.2 in)
100 years	89.2 mm (3.5 in)	Longer than the 63 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, 63 years of values from 1914 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: 74.9 mm (2.9 in) in 1947; 73.9 mm (2.9 in) in 1946; 71.1 mm (2.8 in) in 1920.
