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

61 years with a frost

Across 61 years with a frost, the median last spring frost at Rupert 3 WSW falls on 17 May and the median first autumn frost on 21 September, which leaves a median of 129 days between them.

In 1943 to 1997 the median growing season was 135 days. That is 8 days more than in 1907 to 1941.

Fitted over all years, the growing season changes by +1.2 days per decade at this station.

Frost dates and growing season at Rupert 3 WSW
Measure	Median, all years	Earliest period (1907 to 1941)	Recent period (1943 to 1997)	Recent against earliest	Fitted trend
Last spring frost	17 May	21 May	13 May	8 days earlier	-1.0 days per decade
First autumn frost	21 September	21 September	21 September	no change	+0.3 days per decade
Growing days	129 days	127 days	135 days	8 days more	+1.2 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

72 years, 1907 to 1999

A day with at least 19.5 mm (0.8 in) of rain is expected about once in 2 years. A day with at least 55.3 mm (2.2 in) of rain is expected about once in 100 years.

Rainfall return levels at Rupert 3 WSW: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	19.5 mm (0.8 in)
5 years	27.3 mm (1.1 in)
10 years	33.1 mm (1.3 in)
25 years	41.2 mm (1.6 in)
50 years	48.0 mm (1.9 in)
100 years	55.3 mm (2.2 in)	Longer than the 72 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, 72 years of values from 1907 to 1999.

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: 64.8 mm (2.6 in) in 1907; 46.5 mm (1.8 in) in 1944; 39.6 mm (1.6 in) in 1909.
