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

72 years with a frost

Across 72 years with a frost, the median last spring frost at Roswell Muni AP falls on 11 April and the median first autumn frost on 28 October, which leaves a median of 200 days between them.

In 1943 to 1972 the median growing season was 197 days. That is 5 days fewer than in 1895 to 1930.

Fitted over all years, the growing season changes by -0.8 days per decade at this station.

Frost dates and growing season at Roswell Muni AP
Measure	Median, all years	Earliest period (1895 to 1930)	Recent period (1943 to 1972)	Recent against earliest	Fitted trend
Last spring frost	11 April	14 April	13 April	1 day earlier	+0.6 days per decade
First autumn frost	28 October	28 October	26 October	2 days earlier	-0.2 days per decade
Growing days	200 days	202 days	197 days	5 days fewer	-0.8 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

77 years, 1895 to 1972

A day with at least 39.7 mm (1.6 in) of rain is expected about once in 2 years. A day with at least 146.3 mm (5.8 in) of rain is expected about once in 100 years.

Rainfall return levels at Roswell Muni AP: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	39.7 mm (1.6 in)
5 years	60.3 mm (2.4 in)
10 years	76.7 mm (3.0 in)
25 years	101.0 mm (4.0 in)
50 years	122.2 mm (4.8 in)
100 years	146.3 mm (5.8 in)	Longer than the 77 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, 77 years of values from 1895 to 1972.

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: 143.5 mm (5.6 in) in 1901; 116.1 mm (4.6 in) in 1916; 114.8 mm (4.5 in) in 1898.
