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
70 years with a frostAcross 70 years with a frost, the median last spring frost at Vinton falls on 29 April and the median first autumn frost on 5 October, which leaves a median of 159 days between them.
In 1994 to 2025 the median growing season was 163 days. That is 6 days more than in 1942 to 1977.
Fitted over all years, the growing season changes by +1.9 days per decade at this station.
| Measure | Median, all years | Earliest period (1942 to 1977) | Recent period (1994 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 29 April | 1 May | 29 April | 2 days earlier | -0.9 days per decade |
| First autumn frost | 5 October | 1 October | 9 October | 8 days later | +1.1 days per decade |
| Growing days | 159 days | 157 days | 163 days | 6 days more | +1.9 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
86 years, 1893 to 2025A day with at least 57.7 mm (2.3 in) of rain is expected about once in 2 years. A day with at least 171.2 mm (6.7 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 57.7 mm (2.3 in) | |
| 5 years | 79.5 mm (3.1 in) | |
| 10 years | 96.8 mm (3.8 in) | |
| 25 years | 122.8 mm (4.8 in) | |
| 50 years | 145.4 mm (5.7 in) | |
| 100 years | 171.2 mm (6.7 in) | Longer than the 86 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, 86 years of values from 1893 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: 183.6 mm (7.2 in) in 1977; 158.8 mm (6.3 in) in 2016; 147.3 mm (5.8 in) in 1968.

No change in the annual mean temperature of this station was found against its neighbours.
Climate Twins
2010 to 2025 against 1961 to 1990Over 2010 to 2025, Vinton had a mean temperature of 9.0 C (48.2 F) and 900.0 mm (35.4 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Dixon Wwtp (United States, 209 km away), Bellevue L/D 12 (United States, 132 km away) and Maquoketa (United States, 111 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Dixon Wwtp | United States | 209 km (130 mi) | 9.2 C (48.6 F) | 888.0 mm (35.0 in) | 0.56 |
| Bellevue L/D 12 | United States | 132 km (82 mi) | 9.1 C (48.3 F) | 850.5 mm (33.5 in) | 0.60 |
| Maquoketa | United States | 111 km (69 mi) | 9.0 C (48.2 F) | 900.4 mm (35.4 in) | 0.65 |
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.
