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 44.7 mm (1.8 in) of rain is expected about once in 2 years. A day with at least 182.1 mm (7.2 in) of rain is expected about once in 100 years.

Rainfall return levels at Deerwood: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	44.7 mm (1.8 in)
5 years	67.6 mm (2.7 in)
10 years	87.1 mm (3.4 in)
25 years	118.3 mm (4.7 in)
50 years	147.2 mm (5.8 in)	Longer than the 30 years of record
100 years	182.1 mm (7.2 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: 128.3 mm (5.1 in) in 1952; 121.9 mm (4.8 in) in 1953; 111.8 mm (4.4 in) in 1968.
