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

63 years with a frost

Across 63 years with a frost, the median last spring frost at Gassaway falls on 25 April and the median first autumn frost on 21 October, which leaves a median of 178 days between them.

In 1995 to 2025 the median growing season was 186 days. That is 17 days more than in 1953 to 1991.

Fitted over all years, the growing season changes by +3.5 days per decade at this station.

Frost dates and growing season at Gassaway
Measure	Median, all years	Earliest period (1953 to 1991)	Recent period (1995 to 2025)	Recent against earliest	Fitted trend
Last spring frost	25 April	2 May	23 April	9 days earlier	-1.3 days per decade
First autumn frost	21 October	19 October	25 October	6 days later	+2.2 days per decade
Growing days	178 days	169 days	186 days	17 days more	+3.5 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

71 years, 1952 to 2025

A day with at least 55.5 mm (2.2 in) of rain is expected about once in 2 years. A day with at least 116.9 mm (4.6 in) of rain is expected about once in 100 years.

Rainfall return levels at Gassaway: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	55.5 mm (2.2 in)
5 years	70.2 mm (2.8 in)
10 years	80.7 mm (3.2 in)
25 years	94.6 mm (3.7 in)
50 years	105.5 mm (4.2 in)
100 years	116.9 mm (4.6 in)	Longer than the 71 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, 71 years of values from 1952 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: 109.2 mm (4.3 in) in 1985; 101.6 mm (4.0 in) in 1996; 95.5 mm (3.8 in) in 1971.

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, Gassaway had a mean temperature of 12.6 C (54.7 F) and 1,239.7 mm (48.8 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Baxter (United States, 302 km away), Richmond (United States, 326 km away) and Hyden (United States, 284 km away).

Climate twins of Gassaway: stations whose 1961 to 1990 climate is closest to its 2011 to 2025 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Baxter	United States	302 km (188 mi)	12.6 C (54.7 F)	1,261.9 mm (49.7 in)	0.63
Richmond	United States	326 km (203 mi)	12.7 C (54.9 F)	1,241.8 mm (48.9 in)	0.67
Hyden	United States	284 km (176 mi)	12.4 C (54.3 F)	1,210.7 mm (47.7 in)	0.69

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.
