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
67 years with a frostAcross 67 years with a frost, the median last spring frost at Keshan falls on 3 May and the median first autumn frost on 30 September, which leaves a median of 149 days between them.
In 1988 to 2024 the median growing season was 159 days. That is 15 days more than in 1951 to 1980.
Fitted over all years, the growing season changes by +3.3 days per decade at this station.
| Measure | Median, all years | Earliest period (1951 to 1980) | Recent period (1988 to 2024) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 3 May | 8 May | 28 April | 10 days earlier | -2.3 days per decade |
| First autumn frost | 30 September | 28 September | 5 October | 7 days later | +1.1 days per decade |
| Growing days | 149 days | 144 days | 159 days | 15 days more | +3.3 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.

| 50 years | 128.9 mm (5.1 in) | |
| 100 years | 146.6 mm (5.8 in) | Longer than the 64 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, 64 years of values from 1951 to 2022.
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: 177.9 mm (7.0 in) in 1957; 105.3 mm (4.1 in) in 1961; 101.6 mm (4.0 in) in 1972.
Station Changes
2 suspected2 changes were suspected in the annual mean temperature of Keshan, at 1972 and 1978. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1972 ran 0.5 C (1.0 F) higher than in the years before (possible change).
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1978 ran 0.4 C (0.7 F) lower than in the years before (likely change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1972 | +0.5 | +1.0 | possible | 5 |
| 1978 | -0.4 | -0.7 | 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
2003 to 2024 against 1961 to 1990Over 2003 to 2024, Keshan had a mean temperature of 2.8 C (37.1 F) and 518.8 mm (20.4 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Tonghe (China, 317 km away), Fujin (China, 466 km away) and Ekaterino-Nikolskoe (Russia, 381 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Tonghe | China | 317 km (197 mi) | 2.5 C (36.6 F) | 587.3 mm (23.1 in) | 0.87 |
| Fujin | China | 466 km (290 mi) | 3.0 C (37.3 F) | 509.2 mm (20.0 in) | 0.93 |
| Ekaterino-Nikolskoe | Russia | 381 km (237 mi) | 2.6 C (36.7 F) | 622.6 mm (24.5 in) | 1.01 |
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.
