27 years with a frostAcross 27 years with a frost, the median last spring frost at Smithers Cda falls on 20 June and the median first autumn frost on 8 July, which leaves a median of 24 days between them.
Fitted over all years, the growing season changes by -1.9 days per decade at this station.
| Measure | Median, all years | Earliest period | Recent period (1939 to 1967) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 20 June | n/a | 20 June | n/a | +3.3 days per decade |
| First autumn frost | 8 July | n/a | 8 July | n/a | +1.4 days per decade |
| Growing days | 24 days | n/a | 24 days | n/a | -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
30 years, 1938 to 1967A day with at least 29.2 mm (1.1 in) of rain is expected about once in 2 years. A day with at least 55.2 mm (2.2 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 29.2 mm (1.1 in) | |
| 5 years | 37.8 mm (1.5 in) | |
| 10 years | 42.7 mm (1.7 in) | |
| 25 years | 48.3 mm (1.9 in) | |
| 50 years | 51.9 mm (2.0 in) | Longer than the 30 years of record |
| 100 years | 55.2 mm (2.2 in) | Longer than the 30 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, 30 years of values from 1938 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: 50.8 mm (2.0 in) in 1945; 50.0 mm (2.0 in) in 1951; 42.2 mm (1.7 in) in 1947.
