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

72 years with a frost

Across 72 years with a frost, the median last spring frost at Brucefield falls on 20 May and the median first autumn frost on 4 October, which leaves a median of 140 days between them.

In 1947 to 1983 the median growing season was 138 days. That is 1 day fewer than in 1904 to 1933.

Fitted over all years, the growing season changes by +0.4 days per decade at this station.

Frost dates and growing season at Brucefield
Measure	Median, all years	Earliest period (1904 to 1933)	Recent period (1947 to 1983)	Recent against earliest	Fitted trend
Last spring frost	20 May	22 May	19 May	3 days earlier	-0.3 days per decade
First autumn frost	4 October	5 October	6 October	1 day later	+0.1 days per decade
Growing days	140 days	139 days	138 days	1 day fewer	+0.4 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

64 years, 1904 to 1983

A day with at least 40.3 mm (1.6 in) of rain is expected about once in 2 years. A day with at least 109.6 mm (4.3 in) of rain is expected about once in 100 years.

Rainfall return levels at Brucefield: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	40.3 mm (1.6 in)
5 years	52.5 mm (2.1 in)
10 years	62.7 mm (2.5 in)
25 years	78.4 mm (3.1 in)
50 years	92.7 mm (3.6 in)
100 years	109.6 mm (4.3 in)	Longer than the 64 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, 64 years of values from 1904 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: 129.5 mm (5.1 in) in 1908; 83.8 mm (3.3 in) in 1975; 81.3 mm (3.2 in) in 1958.
