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

81 years with a frost

Across 81 years with a frost, the median last spring frost at Gallipolis falls on 25 April and the median first autumn frost on 17 October, which leaves a median of 173 days between them.

In 1992 to 2025 the median growing season was 189 days. That is 25 days more than in 1935 to 1966.

Fitted over all years, the growing season changes by +4.1 days per decade at this station.

Frost dates and growing season at Gallipolis
Measure	Median, all years	Earliest period (1935 to 1966)	Recent period (1992 to 2025)	Recent against earliest	Fitted trend
Last spring frost	25 April	27 April	21 April	6 days earlier	-1.5 days per decade
First autumn frost	17 October	8 October	26 October	18 days later	+2.6 days per decade
Growing days	173 days	164 days	189 days	25 days more	+4.1 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

92 years, 1929 to 2025

A day with at least 55.6 mm (2.2 in) of rain is expected about once in 2 years. A day with at least 114.8 mm (4.5 in) of rain is expected about once in 100 years.

Rainfall return levels at Gallipolis: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	55.6 mm (2.2 in)
5 years	70.2 mm (2.8 in)
10 years	80.3 mm (3.2 in)
25 years	93.7 mm (3.7 in)
50 years	104.1 mm (4.1 in)
100 years	114.8 mm (4.5 in)	Longer than the 92 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, 92 years of values from 1929 to 2025.

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: 120.1 mm (4.7 in) in 1976; 108.0 mm (4.3 in) in 1963; 101.6 mm (4.0 in) in 2004.

No change in the annual mean temperature of this station was found against its neighbours.

Climate Twins

2011 to 2025 against 1961 to 1990

Over 2011 to 2025, Gallipolis had a mean temperature of 13.4 C (56.1 F) and 1,149.5 mm (45.3 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Dalecarlia Rsvr (United States, 439 km away), US Soldiers Home Dc (United States, 447 km away) and Natl Arboretum Dc (United States, 451 km away).

Dalecarlia Rsvr	United States	439 km (273 mi)	13.3 C (56.0 F)	1,103.4 mm (43.4 in)	0.57
US Soldiers Home Dc	United States	447 km (278 mi)	13.3 C (56.0 F)	1,081.1 mm (42.6 in)	0.60
Natl Arboretum Dc	United States	451 km (280 mi)	13.4 C (56.1 F)	1,076.1 mm (42.4 in)	0.63

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.
