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

34 years with a frost

Across 34 years with a frost, the median last spring frost at Norseman falls on 18 August and the median first autumn frost on 25 June, which leaves a median of 313 days between them.

Fitted over all years, the growing season changes by -0.2 days per decade at this station.

Frost dates and growing season at Norseman
Measure	Median, all years	Earliest period	Recent period (1961 to 2002)	Recent against earliest	Fitted trend
Last spring frost	18 August	n/a	17 August	n/a	+0.3 days per decade
First autumn frost	25 June	n/a	28 June	n/a	+0.2 days per decade
Growing days	313 days	n/a	316 days	n/a	-0.2 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

102 years, 1907 to 2010

A day with at least 29.3 mm (1.2 in) of rain is expected about once in 2 years. A day with at least 111.8 mm (4.4 in) of rain is expected about once in 100 years.

Rainfall return levels at Norseman: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	29.3 mm (1.2 in)
5 years	43.6 mm (1.7 in)
10 years	55.6 mm (2.2 in)
25 years	74.4 mm (2.9 in)
50 years	91.5 mm (3.6 in)
100 years	111.8 mm (4.4 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 102 years of values from 1907 to 2010.

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: 163.6 mm (6.4 in) in 1948; 86.0 mm (3.4 in) in 2000; 81.3 mm (3.2 in) in 1963.
