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 Bar Harbor 3 NW falls on 8 May and the median first autumn frost on 10 October, which leaves a median of 152 days between them.

In 1947 to 1979 the median growing season was 164 days. That is 17 days more than in 1893 to 1941.

Fitted over all years, the growing season changes by +4.3 days per decade at this station.

Frost dates and growing season at Bar Harbor 3 NW
Measure	Median, all years	Earliest period (1893 to 1941)	Recent period (1947 to 1979)	Recent against earliest	Fitted trend
Last spring frost	8 May	14 May	4 May	10 days earlier	-1.8 days per decade
First autumn frost	10 October	5 October	16 October	11 days later	+2.5 days per decade
Growing days	152 days	147 days	164 days	17 days more	+4.3 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

69 years, 1893 to 1981

A day with at least 69.5 mm (2.7 in) of rain is expected about once in 2 years. A day with at least 164.0 mm (6.5 in) of rain is expected about once in 100 years.

Rainfall return levels at Bar Harbor 3 NW: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	69.5 mm (2.7 in)
5 years	91.1 mm (3.6 in)
10 years	106.9 mm (4.2 in)
25 years	128.4 mm (5.1 in)
50 years	145.7 mm (5.7 in)
100 years	164.0 mm (6.5 in)	Longer than the 69 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, 69 years of values from 1893 to 1981.

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: 160.0 mm (6.3 in) in 1961; 153.7 mm (6.1 in) in 1904; 152.4 mm (6.0 in) in 1902.
