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

44 years with a frost

Across 44 years with a frost, the median last spring frost at Mitchell Post Office falls on 1 September and the median first autumn frost on 30 May, which leaves a median of 271 days between them.

Fitted over all years, the growing season changes by +0.7 days per decade at this station.

Frost dates and growing season at Mitchell Post Office
Measure	Median, all years	Earliest period	Recent period (1992 to 2025)	Recent against earliest	Fitted trend
Last spring frost	1 September	n/a	27 August	n/a	-2.5 days per decade
First autumn frost	30 May	n/a	27 May	n/a	-1.8 days per decade
Growing days	271 days	n/a	272 days	n/a	+0.7 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, 1888 to 2025

A day with at least 60.5 mm (2.4 in) of rain is expected about once in 2 years. A day with at least 182.8 mm (7.2 in) of rain is expected about once in 100 years.

Rainfall return levels at Mitchell 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	60.5 mm (2.4 in)
5 years	87.2 mm (3.4 in)
10 years	107.1 mm (4.2 in)
25 years	135.0 mm (5.3 in)
50 years	157.9 mm (6.2 in)
100 years	182.8 mm (7.2 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 1888 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: 186.7 mm (7.4 in) in 1914; 165.6 mm (6.5 in) in 2010; 157.6 mm (6.2 in) in 2016.

Year	Shift (C)	Shift (F)	Strength	Neighbours
1998	+0.1	+0.3	possible	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.
