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
73 years with a frostAcross 73 years with a frost, the median last spring frost at Winfield Locks falls on 16 April and the median first autumn frost on 27 October, which leaves a median of 192 days between them.
In 1989 to 2025 the median growing season was 196 days. That is 9 days more than in 1940 to 1970.
Fitted over all years, the growing season changes by +1.6 days per decade at this station.
| Measure | Median, all years | Earliest period (1940 to 1970) | Recent period (1989 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 16 April | 20 April | 15 April | 5 days earlier | -0.6 days per decade |
| First autumn frost | 27 October | 25 October | 29 October | 4 days later | +0.9 days per decade |
| Growing days | 192 days | 187 days | 196 days | 9 days more | +1.6 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.
Rainfall Return Levels
83 years, 1939 to 2025A day with at least 53.2 mm (2.1 in) of rain is expected about once in 2 years. A day with at least 104.0 mm (4.1 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 53.2 mm (2.1 in) | |
| 5 years | 65.8 mm (2.6 in) | |
| 10 years | 74.5 mm (2.9 in) | |
| 25 years | 86.0 mm (3.4 in) | |
| 50 years | 94.9 mm (3.7 in) | |
| 100 years | 104.0 mm (4.1 in) | Longer than the 83 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, 83 years of values from 1939 to 2025.
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: 102.9 mm (4.1 in) in 1939; 101.6 mm (4.0 in) in 2003; 99.6 mm (3.9 in) in 2005.

Climate Twins
2006 to 2025 against 1961 to 1990Over 2006 to 2025, Winfield Locks had a mean temperature of 13.3 C (56.0 F) and 958.1 mm (37.7 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Fredericksburg Np (United States, 390 km away), Columbia 2SSE (United States, 341 km away) and Lynchburg Rgnl AP (United States, 273 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Fredericksburg Np | United States | 390 km (242 mi) | 13.2 C (55.8 F) | 989.3 mm (38.9 in) | 0.58 |
| Columbia 2SSE | United States | 341 km (212 mi) | 13.2 C (55.7 F) | 1,050.6 mm (41.4 in) | 0.61 |
| Lynchburg Rgnl AP | United States | 273 km (170 mi) | 13.3 C (55.9 F) | 1,039.6 mm (40.9 in) | 0.62 |
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.
