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

47 years with a frost

Across 47 years with a frost, the median last spring frost at Dwellingup falls on 26 August and the median first autumn frost on 2 July, which leaves a median of 322 days between them.

Fitted over all years, the growing season changes by +2.7 days per decade at this station.

Frost dates and growing season at Dwellingup
Measure	Median, all years	Earliest period	Recent period (1979 to 2018)	Recent against earliest	Fitted trend
Last spring frost	26 August	n/a	20 August	n/a	-2.8 days per decade
First autumn frost	2 July	n/a	3 July	n/a	-0.1 days per decade
Growing days	322 days	n/a	323 days	n/a	+2.7 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

91 years, 1934 to 2025

A day with at least 59.8 mm (2.4 in) of rain is expected about once in 2 years. A day with at least 139.1 mm (5.5 in) of rain is expected about once in 100 years.

Rainfall return levels at Dwellingup: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	59.8 mm (2.4 in)
5 years	75.7 mm (3.0 in)
10 years	88.1 mm (3.5 in)
25 years	106.3 mm (4.2 in)
50 years	121.8 mm (4.8 in)
100 years	139.1 mm (5.5 in)	Longer than the 91 years of record

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 91 years of values from 1934 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: 177.5 mm (7.0 in) in 1955; 114.8 mm (4.5 in) in 1945; 111.8 mm (4.4 in) in 1939.

Year	Shift (C)	Shift (F)	Strength	Neighbours
1992	+0.1	+0.1	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.

Climate Twins

2011 to 2025 against 1961 to 1990

Over 2011 to 2025, Dwellingup had a mean temperature of 16.8 C (62.2 F) and 1,056.2 mm (41.6 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are La Estanzuela (Eele) (Uruguay, 12,520 km away), Mercedes (Uruguay, 12,655 km away) and Lucas Heights (Ansto) (Australia, 3,230 km away).

Climate twins of Dwellingup: stations whose 1961 to 1990 climate is closest to its 2011 to 2025 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
La Estanzuela (Eele)	Uruguay	12,520 km (7,780 mi)	16.3 C (61.4 F)	1,086.7 mm (42.8 in)	0.66
Mercedes	Uruguay	12,655 km (7,863 mi)	17.3 C (63.2 F)	1,046.6 mm (41.2 in)	0.89
Lucas Heights (Ansto)	Australia	3,230 km (2,007 mi)	16.9 C (62.3 F)	1,031.6 mm (40.6 in)	1.00

Twins are stations, not cities. A twin is one of the three stations at least 100 km away whose earlier climate is closest to this station's recent one, so a close match does not mean the two places look alike in other ways. A station move or a gap in a record can change that station's averages. The list describes past climate; it is not a forecast and does not say what caused any change. How twins are found, and a search for any station.
