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.

Rainfall Return Levels

66 years, 1951 to 2024

A day with at least 65.0 mm (2.6 in) of rain is expected about once in 2 years. A day with at least 154.5 mm (6.1 in) of rain is expected about once in 100 years.

Rainfall return levels at Xichang: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	65.0 mm (2.6 in)
5 years	84.2 mm (3.3 in)
10 years	98.6 mm (3.9 in)
25 years	119.1 mm (4.7 in)
50 years	136.0 mm (5.4 in)
100 years	154.5 mm (6.1 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 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: 135.7 mm (5.3 in) in 1951; 128.7 mm (5.1 in) in 2000; 125.5 mm (4.9 in) in 1987.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Xichang, at 1957. Each is measured against neighbouring stations.

Relative to 4 neighbouring stations, the station's annual mean temperature from 1957 ran 0.4 C (0.7 F) higher than in the years before (likely change).

Suspected changes in the annual mean temperature at Xichang, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1957	+0.4	+0.7	likely	4

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, Xichang had a mean temperature of 18.9 C (66.0 F) and 948.8 mm (37.4 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Mengzi (China, 515 km away), Lincang (China, 485 km away) and Villa Mainero (Mexico, 13,731 km away).

Climate twins of Xichang: 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
Mengzi	China	515 km (320 mi)	19.5 C (67.2 F)	844.8 mm (33.3 in)	1.30
Lincang	China	485 km (301 mi)	18.3 C (64.9 F)	1,171.2 mm (46.1 in)	1.53
Villa Mainero	Mexico	13,731 km (8,532 mi)	20.4 C (68.6 F)	1,040.3 mm (41.0 in)	1.70

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.
