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
61 years with a frostAcross 61 years with a frost, the median last spring frost at Saint Charles falls on 19 March and the median first autumn frost on 6 November, which leaves a median of 234 days between them.
In 1970 to 2024 the median growing season was 243 days. That is 13 days more than in 1938 to 1968.
Fitted over all years, the growing season changes by +2.8 days per decade at this station.
| Measure | Median, all years | Earliest period (1938 to 1968) | Recent period (1970 to 2024) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 19 March | 19 March | 17 March | 2 days earlier | -0.9 days per decade |
| First autumn frost | 6 November | 3 November | 12 November | 9 days later | +1.8 days per decade |
| Growing days | 234 days | 230 days | 243 days | 13 days more | +2.8 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
67 years, 1937 to 2024A day with at least 87.9 mm (3.5 in) of rain is expected about once in 2 years. A day with at least 185.0 mm (7.3 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 87.9 mm (3.5 in) | |
| 5 years | 111.2 mm (4.4 in) | |
| 10 years | 127.7 mm (5.0 in) | |
| 25 years | 149.8 mm (5.9 in) | |
| 50 years | 167.0 mm (6.6 in) | |
| 100 years | 185.0 mm (7.3 in) | Longer than the 67 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, 67 years of values from 1937 to 2024.
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: 233.2 mm (9.2 in) in 1973; 151.9 mm (6.0 in) in 1965; 139.7 mm (5.5 in) in 2005.
