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

63 years with a frost

Across 63 years with a frost, the median last spring frost at Sherbrooke falls on 15 May and the median first autumn frost on 26 September, which leaves a median of 132 days between them.

In 1941 to 1971 the median growing season was 138 days. That is 11 days more than in 1904 to 1937.

Fitted over all years, the growing season changes by +3.5 days per decade at this station.

Frost dates and growing season at Sherbrooke
Measure	Median, all years	Earliest period (1904 to 1937)	Recent period (1941 to 1971)	Recent against earliest	Fitted trend
Last spring frost	15 May	20 May	12 May	8 days earlier	-1.8 days per decade
First autumn frost	26 September	25 September	27 September	2 days later	+1.7 days per decade
Growing days	132 days	127 days	138 days	11 days more	+3.5 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

68 years, 1904 to 1971

A day with at least 43.3 mm (1.7 in) of rain is expected about once in 2 years. A day with at least 116.2 mm (4.6 in) of rain is expected about once in 100 years.

Rainfall return levels at Sherbrooke: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	43.3 mm (1.7 in)
5 years	59.6 mm (2.3 in)
10 years	71.5 mm (2.8 in)
25 years	88.2 mm (3.5 in)
50 years	101.7 mm (4.0 in)
100 years	116.2 mm (4.6 in)	Longer than the 68 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, 68 years of values from 1904 to 1971.

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: 109.0 mm (4.3 in) in 1942; 97.5 mm (3.8 in) in 1943; 89.7 mm (3.5 in) in 1937.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Sherbrooke, at 1935. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1935 ran 0.2 C (0.3 F) lower than in the years before (likely change).

Suspected changes in the annual mean temperature at Sherbrooke, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1935	-0.2	-0.3	likely	5

Possible change at the station (a move, a new instrument or a new site); the record is kept as measured. A "likely" change has a larger test statistic than a "possible" one. Neither says why the station differs from its neighbours. How changes are found, and the largest ones.
