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
57 years with a frostAcross 57 years with a frost, the median last spring frost at Halifax falls on 11 May and the median first autumn frost on 13 October, which leaves a median of 154 days between them.
Fitted over all years, the growing season changes by -1.0 days per decade at this station.
| Measure | Median, all years | Earliest period | Recent period (1902 to 1932) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 11 May | n/a | 15 May | n/a | +0.6 days per decade |
| First autumn frost | 13 October | n/a | 11 October | n/a | -0.5 days per decade |
| Growing days | 154 days | n/a | 150 days | n/a | -1.0 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
59 years, 1872 to 1932A day with at least 65.3 mm (2.6 in) of rain is expected about once in 2 years. A day with at least 151.1 mm (5.9 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 65.3 mm (2.6 in) | |
| 5 years | 84.1 mm (3.3 in) | |
| 10 years | 98.0 mm (3.9 in) | |
| 25 years | 117.6 mm (4.6 in) | |
| 50 years | 133.7 mm (5.3 in) | |
| 100 years | 151.1 mm (5.9 in) | Longer than the 59 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, 59 years of values from 1872 to 1932.
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: 137.9 mm (5.4 in) in 1908; 131.1 mm (5.2 in) in 1927; 127.3 mm (5.0 in) in 1886.
Station Changes
1 suspectedOne change was suspected in the annual mean temperature of Halifax, at 1927. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1927 ran 0.3 C (0.5 F) lower than in the years before (possible change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1927 | -0.3 | -0.5 | 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.
