Fitted over all years, the growing season changes by -1.1 days per decade at this station.

Frost dates and growing season at Pelly Ranch
Measure	Median, all years	Earliest period	Recent period (1957 to 1983)	Recent against earliest	Fitted trend
Last spring frost	14 June	n/a	14 June	n/a	+1.8 days per decade
First autumn frost	20 August	n/a	20 August	n/a	+0.6 days per decade
Growing days	64 days	n/a	64 days	n/a	-1.1 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

30 years, 1952 to 1983

A day with at least 17.6 mm (0.7 in) of rain is expected about once in 2 years. A day with at least 41.4 mm (1.6 in) of rain is expected about once in 100 years.

Rainfall return levels at Pelly Ranch: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	17.6 mm (0.7 in)
5 years	24.1 mm (0.9 in)
10 years	28.4 mm (1.1 in)
25 years	33.7 mm (1.3 in)
50 years	37.5 mm (1.5 in)	Longer than the 30 years of record
100 years	41.4 mm (1.6 in)	Longer than the 30 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, 30 years of values from 1952 to 1983.

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: 34.8 mm (1.4 in) in 1960; 31.0 mm (1.2 in) in 1969; 30.7 mm (1.2 in) in 1958.
