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
82 years with a frostAcross 82 years with a frost, the median last spring frost at McGrath AP falls on 19 May and the median first autumn frost on 4 September, which leaves a median of 108 days between them.
In 1994 to 2024 the median growing season was 117 days. That is 12 days more than in 1942 to 1971.
Fitted over all years, the growing season changes by +1.6 days per decade at this station.
| Measure | Median, all years | Earliest period (1942 to 1971) | Recent period (1994 to 2024) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 19 May | 19 May | 18 May | 1 day earlier | -0.8 days per decade |
| First autumn frost | 4 September | 4 September | 9 September | 5 days later | +0.9 days per decade |
| Growing days | 108 days | 105 days | 117 days | 12 days more | +1.6 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
75 years, 1940 to 2014A day with at least 25.3 mm (1.0 in) of rain is expected about once in 2 years. A day with at least 45.1 mm (1.8 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 25.3 mm (1.0 in) | |
| 5 years | 31.9 mm (1.3 in) | |
| 10 years | 35.7 mm (1.4 in) | |
| 25 years | 39.9 mm (1.6 in) | |
| 50 years | 42.6 mm (1.7 in) | |
| 100 years | 45.1 mm (1.8 in) | Longer than the 75 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, 75 years of values from 1940 to 2014.
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: 43.9 mm (1.7 in) in 2000; 40.4 mm (1.6 in) in 1994; 39.6 mm (1.6 in) in 1970.
