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

37 years with a frost

Across 37 years with a frost, the median last spring frost at Cootamundra Post Office falls on 19 September and the median first autumn frost on 16 May, which leaves a median of 240 days between them.

Fitted over all years, the growing season changes by +7.8 days per decade at this station.

Frost dates and growing season at Cootamundra Post Office
Measure	Median, all years	Earliest period	Recent period (1964 to 1994)	Recent against earliest	Fitted trend
Last spring frost	19 September	n/a	19 September	n/a	-4.1 days per decade
First autumn frost	16 May	n/a	20 May	n/a	+3.7 days per decade
Growing days	240 days	n/a	242 days	n/a	+7.8 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

107 years, 1889 to 1995

A day with at least 46.6 mm (1.8 in) of rain is expected about once in 2 years. A day with at least 119.0 mm (4.7 in) of rain is expected about once in 100 years.

Rainfall return levels at Cootamundra Post Office: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	46.6 mm (1.8 in)
5 years	63.6 mm (2.5 in)
10 years	75.8 mm (3.0 in)
25 years	92.2 mm (3.6 in)
50 years	105.3 mm (4.1 in)
100 years	119.0 mm (4.7 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 107 years of values from 1889 to 1995.

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: 129.5 mm (5.1 in) in 1929; 125.2 mm (4.9 in) in 1974; 103.4 mm (4.1 in) in 1962.
