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

52 years with a frost

Across 52 years with a frost, the median last spring frost at Changde falls on 20 February and the median first autumn frost on 17 December, which leaves a median of 298 days between them.

Fitted over all years, the growing season changes by +4.3 days per decade at this station.

Frost dates and growing season at Changde
Measure	Median, all years	Earliest period	Recent period (1976 to 2024)	Recent against earliest	Fitted trend
Last spring frost	20 February	n/a	17 February	n/a	-3.0 days per decade
First autumn frost	17 December	n/a	21 December	n/a	+1.3 days per decade
Growing days	298 days	n/a	307 days	n/a	+4.3 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

67 years, 1951 to 2024

A day with at least 88.5 mm (3.5 in) of rain is expected about once in 2 years. A day with at least 217.8 mm (8.6 in) of rain is expected about once in 100 years.

Rainfall return levels at Changde: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	88.5 mm (3.5 in)
5 years	121.5 mm (4.8 in)
10 years	144.0 mm (5.7 in)
25 years	173.2 mm (6.8 in)
50 years	195.4 mm (7.7 in)
100 years	217.8 mm (8.6 in)	Longer than the 67 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, 67 years of values from 1951 to 2024.

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: 251.1 mm (9.9 in) in 1999; 176.8 mm (7.0 in) in 1954; 164.4 mm (6.5 in) in 2008.

Climate Twins

2003 to 2024 against 1961 to 1990

Over 2003 to 2024, Changde had a mean temperature of 18.5 C (65.3 F) and 1,262.2 mm (49.7 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Lingling (China, 313 km away), Wills Pt (United States, 12,553 km away) and Red Rvr Rsch STN (United States, 12,676 km away).

Climate twins of Changde: stations whose 1961 to 1990 climate is closest to its 2003 to 2024 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Lingling	China	313 km (194 mi)	18.3 C (64.9 F)	1,395.2 mm (54.9 in)	0.84
Wills Pt	United States	12,553 km (7,800 mi)	17.9 C (64.3 F)	1,108.3 mm (43.6 in)	1.00
Red Rvr Rsch STN	United States	12,676 km (7,876 mi)	17.9 C (64.2 F)	1,223.2 mm (48.2 in)	1.04

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.
