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
69 years with a frostAcross 69 years with a frost, the median last spring frost at Merriman falls on 14 May and the median first autumn frost on 21 September, which leaves a median of 132 days between them.
In 1966 to 2004 the median growing season was 138 days. That is 11 days more than in 1918 to 1956.
Fitted over all years, the growing season changes by +2.7 days per decade at this station.
| Measure | Median, all years | Earliest period (1918 to 1956) | Recent period (1966 to 2004) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 14 May | 18 May | 8 May | 10 days earlier | -1.5 days per decade |
| First autumn frost | 21 September | 21 September | 26 September | 5 days later | +1.2 days per decade |
| Growing days | 132 days | 127 days | 138 days | 11 days more | +2.7 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
79 years, 1898 to 2005A day with at least 42.8 mm (1.7 in) of rain is expected about once in 2 years. A day with at least 116.2 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 | 42.8 mm (1.7 in) | |
| 5 years | 59.4 mm (2.3 in) | |
| 10 years | 71.6 mm (2.8 in) | |
| 25 years | 88.3 mm (3.5 in) | |
| 50 years | 101.8 mm (4.0 in) | |
| 100 years | 116.2 mm (4.6 in) | Longer than the 79 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, 79 years of values from 1898 to 2005.
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: 108.0 mm (4.3 in) in 1919; 106.7 mm (4.2 in) in 1998; 96.5 mm (3.8 in) in 1983.
