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

76 years with a frost

Across 76 years with a frost, the median last spring frost at Halsey 2 W falls on 11 May and the median first autumn frost on 27 September, which leaves a median of 141 days between them.

In 1956 to 1988 the median growing season was 131 days. That is 12 days fewer than in 1904 to 1937.

Fitted over all years, the growing season changes by -0.7 days per decade at this station.

Frost dates and growing season at Halsey 2 W
Measure	Median, all years	Earliest period (1904 to 1937)	Recent period (1956 to 1988)	Recent against earliest	Fitted trend
Last spring frost	11 May	11 May	11 May	no change	-0.1 days per decade
First autumn frost	27 September	27 September	24 September	3 days earlier	-0.7 days per decade
Growing days	141 days	143 days	131 days	12 days fewer	-0.7 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

84 years, 1903 to 1988

A day with at least 48.4 mm (1.9 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.

Expected about once in	A day with at least	Note
2 years	48.4 mm (1.9 in)
5 years	65.8 mm (2.6 in)
10 years	77.7 mm (3.1 in)
25 years	93.0 mm (3.7 in)
50 years	104.5 mm (4.1 in)
100 years	116.2 mm (4.6 in)	Longer than the 84 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, 84 years of values from 1903 to 1988.

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: 114.3 mm (4.5 in) in 1987; 113.0 mm (4.4 in) in 1910; 91.4 mm (3.6 in) in 1933.
