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
64 years with a frostAcross 64 years with a frost, the median last spring frost at Dillinger falls on 25 May and the median first autumn frost on 15 September, which leaves a median of 111 days between them.
In 1990 to 2024 the median growing season was 114 days. That is 6 days more than in 1949 to 1985.
Fitted over all years, the growing season changes by +1.6 days per decade at this station.
| Measure | Median, all years | Earliest period (1949 to 1985) | Recent period (1990 to 2024) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 25 May | 26 May | 24 May | 2 days earlier | -0.2 days per decade |
| First autumn frost | 15 September | 13 September | 16 September | 3 days later | +1.4 days per decade |
| Growing days | 111 days | 108 days | 114 days | 6 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
77 years, 1948 to 2025A day with at least 33.8 mm (1.3 in) of rain is expected about once in 2 years. A day with at least 64.3 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 | 33.8 mm (1.3 in) | |
| 5 years | 43.0 mm (1.7 in) | |
| 10 years | 48.7 mm (1.9 in) | |
| 25 years | 55.4 mm (2.2 in) | |
| 50 years | 60.0 mm (2.4 in) | |
| 100 years | 64.3 mm (2.5 in) | Longer than the 77 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, 77 years of values from 1948 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 2015; 56.4 mm (2.2 in) in 1995; 55.4 mm (2.2 in) in 1959.

Climate Twins
2008 to 2024 against 1961 to 1990Over 2008 to 2024, Dillinger had a mean temperature of 7.4 C (45.4 F) and 405.2 mm (16.0 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Casper-Natrona Co AP (United States, 173 km away), Black Mtn (United States, 216 km away) and Bates Creek #2 (United States, 192 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Casper-Natrona Co AP | United States | 173 km (107 mi) | 7.3 C (45.1 F) | 318.9 mm (12.6 in) | 0.96 |
| Black Mtn | United States | 216 km (134 mi) | 7.4 C (45.2 F) | 337.9 mm (13.3 in) | 1.04 |
| Bates Creek #2 | United States | 192 km (119 mi) | 7.2 C (44.9 F) | 315.9 mm (12.4 in) | 1.04 |
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.
