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

70 years with a frost

Across 70 years with a frost, the median last spring frost at Gunnedah Pool falls on 21 August and the median first autumn frost on 15 June, which leaves a median of 295 days between them.

In 1977 to 2010 the median growing season was 313 days. That is 42 days more than in 1879 to 1954.

Fitted over all years, the growing season changes by +3.4 days per decade at this station.

Frost dates and growing season at Gunnedah Pool
Measure	Median, all years	Earliest period (1879 to 1954)	Recent period (1977 to 2010)	Recent against earliest	Fitted trend
Last spring frost	21 August	28 August	16 August	12 days earlier	-0.6 days per decade
First autumn frost	15 June	27 May	24 June	28 days later	+2.8 days per decade
Growing days	295 days	271 days	313 days	42 days more	+3.4 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

137 years, 1878 to 2019

A day with at least 54.8 mm (2.2 in) of rain is expected about once in 2 years. A day with at least 144.5 mm (5.7 in) of rain is expected about once in 100 years.

Rainfall return levels at Gunnedah Pool: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	54.8 mm (2.2 in)
5 years	75.7 mm (3.0 in)
10 years	90.7 mm (3.6 in)
25 years	111.1 mm (4.4 in)
50 years	127.3 mm (5.0 in)
100 years	144.5 mm (5.7 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 137 years of values from 1878 to 2019.

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: 184.0 mm (7.2 in) in 1974; 158.0 mm (6.2 in) in 1941; 127.3 mm (5.0 in) in 1956.
