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
62 years with a frostAcross 62 years with a frost, the median last spring frost at Masset Airport falls on 8 May and the median first autumn frost on 20 October, which leaves a median of 163 days between them.
In 1934 to 1967 the median growing season was 160 days. That is 12 days fewer than in 1900 to 1931.
Fitted over all years, the growing season changes by -3.9 days per decade at this station.
| Measure | Median, all years | Earliest period (1900 to 1931) | Recent period (1934 to 1967) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 8 May | 5 May | 11 May | 6 days later | +3.0 days per decade |
| First autumn frost | 20 October | 20 October | 21 October | 1 day later | -0.9 days per decade |
| Growing days | 163 days | 172 days | 160 days | 12 days fewer | -3.9 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
64 years, 1900 to 1967A day with at least 41.7 mm (1.6 in) of rain is expected about once in 2 years. A day with at least 80.5 mm (3.2 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 41.7 mm (1.6 in) | |
| 5 years | 52.2 mm (2.1 in) | |
| 10 years | 59.1 mm (2.3 in) | |
| 25 years | 67.7 mm (2.7 in) | |
| 50 years | 74.2 mm (2.9 in) | |
| 100 years | 80.5 mm (3.2 in) | Longer than the 64 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, 64 years of values from 1900 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: 68.6 mm (2.7 in) in 1916; 66.3 mm (2.6 in) in 1958; 66.0 mm (2.6 in) in 1919.
Station Changes
2 suspected2 changes were suspected in the annual mean temperature of Masset Airport, at 1929 and 1946. Each is measured against neighbouring stations.
- Relative to 3 neighbouring stations, the station's annual mean temperature from 1929 ran 0.8 C (1.5 F) higher than in the years before (possible change).
- Relative to 3 neighbouring stations, the station's annual mean temperature from 1946 ran 0.5 C (0.9 F) lower than in the years before (likely change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1929 | +0.8 | +1.5 | possible | 3 |
| 1946 | -0.5 | -0.9 | likely | 3 |
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.
