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
66 years with a frostAcross 66 years with a frost, the median last spring frost at Dongtai falls on 18 March and the median first autumn frost on 28 November, which leaves a median of 255 days between them.
In 1989 to 2025 the median growing season was 262 days. That is 12 days more than in 1953 to 1982.
Fitted over all years, the growing season changes by +3.6 days per decade at this station.
| Measure | Median, all years | Earliest period (1953 to 1982) | Recent period (1989 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 18 March | 22 March | 11 March | 11 days earlier | -2.5 days per decade |
| First autumn frost | 28 November | 25 November | 1 December | 6 days later | +1.1 days per decade |
| Growing days | 255 days | 250 days | 262 days | 12 days more | +3.6 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.

| 25 years | 196.7 mm (7.7 in) | |
| 50 years | 229.7 mm (9.0 in) | |
| 100 years | 266.4 mm (10.5 in) | Longer than the 65 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, 65 years of values from 1953 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: 314.3 mm (12.4 in) in 1965; 257.3 mm (10.1 in) in 1960; 207.1 mm (8.2 in) in 1985.
Station Changes
1 suspectedOne change was suspected in the annual mean temperature of Dongtai, at 1981. Each is measured against neighbouring stations.
- Relative to 3 neighbouring stations, the station's annual mean temperature from 1981 ran 0.4 C (0.7 F) lower than in the years before (likely change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1981 | -0.4 | -0.7 | likely | 3 |
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 1990Over 2004 to 2025, Dongtai had a mean temperature of 16.3 C (61.3 F) and 1,062.8 mm (41.8 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Hefei (China, 307 km away), Nanjing (China, 165 km away) and Ft Gibson Dam (United States, 11,528 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Hefei | China | 307 km (191 mi) | 16.1 C (60.9 F) | 975.7 mm (38.4 in) | 0.64 |
| Nanjing | China | 165 km (103 mi) | 15.8 C (60.4 F) | 1,034.7 mm (40.7 in) | 0.68 |
| Ft Gibson Dam | United States | 11,528 km (7,163 mi) | 15.9 C (60.6 F) | 1,070.9 mm (42.2 in) | 0.84 |
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.
