Measure	Median, all years	Earliest period	Recent period (1982 to 2013)	Recent against earliest	Fitted trend
Last spring frost	22 August	n/a	19 August	n/a	-4.8 days per decade
First autumn frost	13 June	n/a	17 June	n/a	+4.5 days per decade
Growing days	291 days	n/a	302 days	n/a	+9.4 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

111 years, 1896 to 2025

A day with at least 45.8 mm (1.8 in) of rain is expected about once in 2 years. A day with at least 123.9 mm (4.9 in) of rain is expected about once in 100 years.

Rainfall return levels at Wyalong 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	45.8 mm (1.8 in)
5 years	64.4 mm (2.5 in)
10 years	77.6 mm (3.1 in)
25 years	95.3 mm (3.8 in)
50 years	109.3 mm (4.3 in)
100 years	123.9 mm (4.9 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 111 years of values from 1896 to 2025.

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: 140.5 mm (5.5 in) in 1962; 105.6 mm (4.2 in) in 1982; 101.1 mm (4.0 in) in 1964.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Wyalong Post Office, at 1984 and 2005. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1984 ran 0.2 C (0.3 F) higher than in the years before (likely change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 2005 ran 0.2 C (0.4 F) higher than in the years before (likely change).

Suspected changes in the annual mean temperature at Wyalong Post Office, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1984	+0.2	+0.3	likely	5
2005	+0.2	+0.4	likely	5

Possible change at the station (a move, a new instrument or a new site); the record is kept as measured. A "likely" change has a larger test statistic than a "possible" one. Neither says why the station differs from its neighbours. How changes are found, and the largest ones.
