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
66 years with a frostAcross 66 years with a frost, the median last spring frost at Toronto Agincourt falls on 10 May and the median first autumn frost on 10 October, which leaves a median of 155 days between them.
In 1935 to 1966 the median growing season was 159 days. That is 10 days more than in 1897 to 1928.
Fitted over all years, the growing season changes by +2.1 days per decade at this station.
| Measure | Median, all years | Earliest period (1897 to 1928) | Recent period (1935 to 1966) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 10 May | 14 May | 8 May | 6 days earlier | -1.1 days per decade |
| First autumn frost | 10 October | 9 October | 12 October | 3 days later | +1.0 days per decade |
| Growing days | 155 days | 149 days | 159 days | 10 days more | +2.1 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
68 years, 1897 to 1967A day with at least 44.8 mm (1.8 in) of rain is expected about once in 2 years. A day with at least 116.1 mm (4.6 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 44.8 mm (1.8 in) | |
| 5 years | 58.9 mm (2.3 in) | |
| 10 years | 70.0 mm (2.8 in) | |
| 25 years | 86.3 mm (3.4 in) | |
| 50 years | 100.3 mm (3.9 in) | |
| 100 years | 116.1 mm (4.6 in) | Longer than the 68 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, 68 years of values from 1897 to 1967.
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: 126.0 mm (5.0 in) in 1915; 84.6 mm (3.3 in) in 1954; 83.3 mm (3.3 in) in 1955.
Station Changes
2 suspected2 changes were suspected in the annual mean temperature of Toronto Agincourt, at 1910 and 1924. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1910 ran 0.3 C (0.5 F) higher than in the years before (likely change).
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1924 ran 0.2 C (0.3 F) higher than in the years before (possible change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1910 | +0.3 | +0.5 | likely | 5 |
| 1924 | +0.2 | +0.3 | possible | 5 |
Possible change at the station (a move, a new instrument or a new site); the record is kept as measured. A "likely" change has a larger test statistic than a "possible" one. Neither says why the station differs from its neighbours. How changes are found, and the largest ones.
