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, 1904 to 1941

A day with at least 41.2 mm (1.6 in) of rain is expected about once in 2 years. A day with at least 104.8 mm (4.1 in) of rain is expected about once in 100 years.

Rainfall return levels at Manfred: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	41.2 mm (1.6 in)
5 years	58.8 mm (2.3 in)
10 years	70.3 mm (2.8 in)
25 years	84.4 mm (3.3 in)
50 years	94.7 mm (3.7 in)	Longer than the 30 years of record
100 years	104.8 mm (4.1 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 1904 to 1941.

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: 95.3 mm (3.8 in) in 1908; 86.4 mm (3.4 in) in 1918; 70.9 mm (2.8 in) in 1919.
