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

86 years with a frost

Across 86 years with a frost, the median last spring frost at Fredericksburg Np falls on 21 April and the median first autumn frost on 20 October, which leaves a median of 184 days between them.

In 1958 to 1994 the median growing season was 177 days. That is 17 days fewer than in 1896 to 1927.

Fitted over all years, the growing season changes by -2.8 days per decade at this station.

Frost dates and growing season at Fredericksburg Np
Measure	Median, all years	Earliest period (1896 to 1927)	Recent period (1958 to 1994)	Recent against earliest	Fitted trend
Last spring frost	21 April	15 April	23 April	8 days later	+1.2 days per decade
First autumn frost	20 October	28 October	18 October	10 days earlier	-1.6 days per decade
Growing days	184 days	194 days	177 days	17 days fewer	-2.8 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

94 years, 1896 to 1996

A day with at least 67.3 mm (2.6 in) of rain is expected about once in 2 years. A day with at least 178.7 mm (7.0 in) of rain is expected about once in 100 years.

Rainfall return levels at Fredericksburg Np: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	67.3 mm (2.6 in)
5 years	93.5 mm (3.7 in)
10 years	112.3 mm (4.4 in)
25 years	137.6 mm (5.4 in)
50 years	157.6 mm (6.2 in)
100 years	178.7 mm (7.0 in)	Longer than the 94 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, 94 years of values from 1896 to 1996.

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: 156.7 mm (6.2 in) in 1942; 149.9 mm (5.9 in) in 1935; 143.5 mm (5.6 in) in 1972.
