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

55 years with a frost

Across 55 years with a frost, the median last spring frost at Nancheng falls on 15 February and the median first autumn frost on 12 December, which leaves a median of 298 days between them.

Fitted over all years, the growing season changes by +2.2 days per decade at this station.

Frost dates and growing season at Nancheng
Measure	Median, all years	Earliest period	Recent period (1980 to 2024)	Recent against earliest	Fitted trend
Last spring frost	15 February	n/a	6 February	n/a	-1.2 days per decade
First autumn frost	12 December	n/a	14 December	n/a	+1.0 days per decade
Growing days	298 days	n/a	302 days	n/a	+2.2 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

66 years, 1952 to 2024

A day with at least 97.8 mm (3.9 in) of rain is expected about once in 2 years. A day with at least 250.7 mm (9.9 in) of rain is expected about once in 100 years.

Rainfall return levels at Nancheng: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	97.8 mm (3.9 in)
5 years	132.7 mm (5.2 in)
10 years	158.0 mm (6.2 in)
25 years	192.8 mm (7.6 in)
50 years	220.9 mm (8.7 in)
100 years	250.7 mm (9.9 in)	Longer than the 66 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, 66 years of values from 1952 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: 289.5 mm (11.4 in) in 1967; 234.2 mm (9.2 in) in 2023; 189.4 mm (7.5 in) in 2010.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Nancheng, at 1969 and 2020. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1969 ran 0.3 C (0.5 F) lower than in the years before (likely change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 2020 ran 0.3 C (0.5 F) higher than in the years before (likely change).

Suspected changes in the annual mean temperature at Nancheng, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1969	-0.3	-0.5	likely	5
2020	+0.3	+0.5	likely	5

Possible change at the station (a move, a new instrument or a new site); the record is kept as measured. A "likely" change has a larger test statistic than a "possible" one. Neither says why the station differs from its neighbours. How changes are found, and the largest ones.

Climate Twins

2004 to 2025 against 1961 to 1990

Over 2004 to 2025, Nancheng had a mean temperature of 19.6 C (67.3 F) and 1,818.8 mm (71.6 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Guilin (China, 680 km away), Jian (China, 174 km away) and Nanping (China, 170 km away).

Climate twins of Nancheng: stations whose 1961 to 1990 climate is closest to its 2004 to 2025 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Guilin	China	680 km (423 mi)	19.4 C (67.0 F)	1,853.8 mm (73.0 in)	1.08
Jian	China	174 km (108 mi)	18.9 C (66.0 F)	1,473.3 mm (58.0 in)	1.65
Nanping	China	170 km (106 mi)	20.2 C (68.4 F)	1,616.5 mm (63.6 in)	1.73

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.
