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

64 years with a frost

Across 64 years with a frost, the median last spring frost at Hogsett Rc Byrd Dam falls on 20 April and the median first autumn frost on 20 October, which leaves a median of 184 days between them.

In 1993 to 2023 the median growing season was 194 days. That is 19 days more than in 1950 to 1986.

Fitted over all years, the growing season changes by +3.9 days per decade at this station.

Frost dates and growing season at Hogsett Rc Byrd Dam
Measure	Median, all years	Earliest period (1950 to 1986)	Recent period (1993 to 2023)	Recent against earliest	Fitted trend
Last spring frost	20 April	28 April	13 April	15 days earlier	-2.4 days per decade
First autumn frost	20 October	17 October	25 October	8 days later	+1.5 days per decade
Growing days	184 days	175 days	194 days	19 days more	+3.9 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

102 years, 1916 to 2023

A day with at least 54.0 mm (2.1 in) of rain is expected about once in 2 years. A day with at least 119.7 mm (4.7 in) of rain is expected about once in 100 years.

Rainfall return levels at Hogsett Rc Byrd Dam: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	54.0 mm (2.1 in)
5 years	68.7 mm (2.7 in)
10 years	79.5 mm (3.1 in)
25 years	94.5 mm (3.7 in)
50 years	106.7 mm (4.2 in)
100 years	119.7 mm (4.7 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 102 years of values from 1916 to 2023.

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: 121.4 mm (4.8 in) in 2004; 119.4 mm (4.7 in) in 1996; 110.7 mm (4.4 in) in 1985.

Climate Twins

2009 to 2023 against 1961 to 1990

Over 2009 to 2023, Hogsett Rc Byrd Dam had a mean temperature of 12.8 C (55.0 F) and 1,061.0 mm (41.8 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Piedmont Rsch STN (United States, 358 km away), Glenn Dale Bell STN (United States, 467 km away) and Carrollton Lock 1 (United States, 257 km away).

Twins are stations, not cities. A twin is one of the three stations at least 100 km away whose earlier climate is closest to this station's recent one, so a close match does not mean the two places look alike in other ways. A station move or a gap in a record can change that station's averages. The list describes past climate; it is not a forecast and does not say what caused any change. How twins are found, and a search for any station.
