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

42 years with a frost

Across 42 years with a frost, the median last spring frost at Brookton falls on 17 September and the median first autumn frost on 24 June, which leaves a median of 275 days between them.

Fitted over all years, the growing season changes by +6.9 days per decade at this station.

Frost dates and growing season at Brookton
Measure	Median, all years	Earliest period	Recent period (1994 to 2024)	Recent against earliest	Fitted trend
Last spring frost	17 September	n/a	16 September	n/a	-4.5 days per decade
First autumn frost	24 June	n/a	25 June	n/a	+2.4 days per decade
Growing days	275 days	n/a	290 days	n/a	+6.9 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

116 years, 1909 to 2025

A day with at least 36.3 mm (1.4 in) of rain is expected about once in 2 years. A day with at least 90.0 mm (3.5 in) of rain is expected about once in 100 years.

Rainfall return levels at Brookton: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	36.3 mm (1.4 in)
5 years	49.6 mm (2.0 in)
10 years	58.9 mm (2.3 in)
25 years	71.0 mm (2.8 in)
50 years	80.4 mm (3.2 in)
100 years	90.0 mm (3.5 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 116 years of values from 1909 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: 96.6 mm (3.8 in) in 2017; 90.9 mm (3.6 in) in 1963; 82.6 mm (3.3 in) in 1955.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Brookton, at 2005. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 2005 ran 0.1 C (0.2 F) lower than in the years before (possible change).

Suspected changes in the annual mean temperature at Brookton, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
2005	-0.1	-0.2	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.
