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

78 years with a frost

Across 78 years with a frost, the median last spring frost at Gettysburg falls on 19 April and the median first autumn frost on 16 October, which leaves a median of 182 days between them.

In 1952 to 1981 the median growing season was 183 days. That is 5 days more than in 1904 to 1933.

Fitted over all years, the growing season changes by +1.0 days per decade at this station.

Frost dates and growing season at Gettysburg
Measure	Median, all years	Earliest period (1904 to 1933)	Recent period (1952 to 1981)	Recent against earliest	Fitted trend
Last spring frost	19 April	25 April	16 April	9 days earlier	-0.7 days per decade
First autumn frost	16 October	15 October	13 October	2 days earlier	+0.3 days per decade
Growing days	182 days	178 days	183 days	5 days more	+1.0 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

79 years, 1893 to 1981

A day with at least 65.3 mm (2.6 in) of rain is expected about once in 2 years. A day with at least 150.3 mm (5.9 in) of rain is expected about once in 100 years.

Rainfall return levels at Gettysburg: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	65.3 mm (2.6 in)
5 years	86.3 mm (3.4 in)
10 years	100.9 mm (4.0 in)
25 years	120.2 mm (4.7 in)
50 years	135.0 mm (5.3 in)
100 years	150.3 mm (5.9 in)	Longer than the 79 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, 79 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: 146.1 mm (5.8 in) in 1972; 139.7 mm (5.5 in) in 1923; 123.4 mm (4.9 in) in 1916.
