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 Madawaska falls on 16 June and the median first autumn frost on 1 August, which leaves a median of 51 days between them.

In 1949 to 1983 the median growing season was 61 days. That is 22 days more than in 1916 to 1945.

Fitted over all years, the growing season changes by +3.7 days per decade at this station.

Frost dates and growing season at Madawaska
Measure	Median, all years	Earliest period (1916 to 1945)	Recent period (1949 to 1983)	Recent against earliest	Fitted trend
Last spring frost	16 June	18 June	10 June	8 days earlier	-1.7 days per decade
First autumn frost	1 August	24 July	6 August	13 days later	+2.0 days per decade
Growing days	51 days	39 days	61 days	22 days more	+3.7 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

67 years, 1916 to 1983

A day with at least 40.5 mm (1.6 in) of rain is expected about once in 2 years. A day with at least 80.6 mm (3.2 in) of rain is expected about once in 100 years.

Rainfall return levels at Madawaska: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	40.5 mm (1.6 in)
5 years	50.3 mm (2.0 in)
10 years	57.2 mm (2.3 in)
25 years	66.3 mm (2.6 in)
50 years	73.3 mm (2.9 in)
100 years	80.6 mm (3.2 in)	Longer than the 67 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, 67 years of values from 1916 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: 78.7 mm (3.1 in) in 1921; 76.2 mm (3.0 in) in 1965; 68.6 mm (2.7 in) in 1919.
