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
76 years with a frostAcross 76 years with a frost, the median last spring frost at Dunkirk 19NNE falls on 27 May and the median first autumn frost on 10 September, which leaves a median of 107 days between them.
In 1971 to 2025 the median growing season was 109 days. That is 3 days more than in 1922 to 1953.
Fitted over all years, the growing season changes by +0.3 days per decade at this station.
| Measure | Median, all years | Earliest period (1922 to 1953) | Recent period (1971 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 27 May | 27 May | 28 May | 1 day later | +0.1 days per decade |
| First autumn frost | 10 September | 11 September | 13 September | 2 days later | +0.4 days per decade |
| Growing days | 107 days | 106 days | 109 days | 3 days more | +0.3 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.
Rainfall Return Levels
88 years, 1913 to 2025A day with at least 26.9 mm (1.1 in) of rain is expected about once in 2 years. A day with at least 62.4 mm (2.5 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 26.9 mm (1.1 in) | |
| 5 years | 36.7 mm (1.4 in) | |
| 10 years | 43.1 mm (1.7 in) | |
| 25 years | 51.1 mm (2.0 in) | |
| 50 years | 56.8 mm (2.2 in) | |
| 100 years | 62.4 mm (2.5 in) | Longer than the 88 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, 88 years of values from 1913 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: 63.5 mm (2.5 in) in 1916; 59.7 mm (2.4 in) in 1929; 58.7 mm (2.3 in) in 1937.

Climate Twins
2011 to 2025 against 1961 to 1990Over 2011 to 2025, Dunkirk 19NNE had a mean temperature of 5.1 C (41.2 F) and 271.5 mm (10.7 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Lifton Pumping STN (United States, 733 km away), Green Rvr (United States, 816 km away) and Mackay Lost Rvr Rs (United States, 558 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Lifton Pumping STN | United States | 733 km (455 mi) | 5.1 C (41.2 F) | 275.9 mm (10.9 in) | 0.97 |
| Green Rvr | United States | 816 km (507 mi) | 5.4 C (41.8 F) | 177.2 mm (7.0 in) | 1.08 |
| Mackay Lost Rvr Rs | United States | 558 km (347 mi) | 5.1 C (41.1 F) | 251.0 mm (9.9 in) | 1.08 |
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.
