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
52 years with a frostAcross 52 years with a frost, the median last spring frost at St Joseph Rosecrans Mem AP falls on 17 April and the median first autumn frost on 13 October, which leaves a median of 183 days between them.
Fitted over all years, the growing season changes by 0.0 days per decade at this station.
| Measure | Median, all years | Earliest period | Recent period (1979 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 17 April | n/a | 16 April | n/a | -0.1 days per decade |
| First autumn frost | 13 October | n/a | 13 October | n/a | -0.1 days per decade |
| Growing days | 183 days | n/a | 183 days | n/a | 0.0 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
53 years, 1948 to 2025A day with at least 67.7 mm (2.7 in) of rain is expected about once in 2 years. A day with at least 144.6 mm (5.7 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 67.7 mm (2.7 in) | |
| 5 years | 89.2 mm (3.5 in) | |
| 10 years | 103.0 mm (4.1 in) | |
| 25 years | 120.1 mm (4.7 in) | |
| 50 years | 132.5 mm (5.2 in) | |
| 100 years | 144.6 mm (5.7 in) | Longer than the 53 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, 53 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: 120.4 mm (4.7 in) in 2016; 118.1 mm (4.6 in) in 1974; 117.1 mm (4.6 in) in 2022.

Climate Twins
2010 to 2025 against 1961 to 1990Over 2010 to 2025, St Joseph Rosecrans Mem AP had a mean temperature of 12.4 C (54.2 F) and 834.3 mm (32.8 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are St Charles Elm Pt (United States, 393 km away), John Redmond Lake (United States, 183 km away) and Alton - Melvin Price L&D (United States, 422 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| St Charles Elm Pt | United States | 393 km (244 mi) | 12.4 C (54.3 F) | 945.3 mm (37.2 in) | 0.75 |
| John Redmond Lake | United States | 183 km (114 mi) | 12.6 C (54.6 F) | 873.0 mm (34.4 in) | 0.78 |
| Alton - Melvin Price L&D | United States | 422 km (262 mi) | 12.4 C (54.4 F) | 956.6 mm (37.7 in) | 0.80 |
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.
