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.

Rainfall Return Levels

117 years, 1907 to 2025

A day with at least 34.8 mm (1.4 in) of rain is expected about once in 2 years. A day with at least 97.8 mm (3.9 in) of rain is expected about once in 100 years.

Rainfall return levels at Wongan Hills: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	34.8 mm (1.4 in)
5 years	49.0 mm (1.9 in)
10 years	59.4 mm (2.3 in)
25 years	73.8 mm (2.9 in)
50 years	85.4 mm (3.4 in)
100 years	97.8 mm (3.9 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 117 years of values from 1907 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: 86.2 mm (3.4 in) in 2015; 81.3 mm (3.2 in) in 1942; 79.8 mm (3.1 in) in 1939.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Wongan Hills, at 1999 and 2006. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1999 ran 0.2 C (0.4 F) lower than in the years before (possible change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 2006 ran 0.2 C (0.3 F) higher than in the years before (possible change).

Suspected changes in the annual mean temperature at Wongan Hills, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1999	-0.2	-0.4	possible	5
2006	+0.2	+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.

Climate Twins

2010 to 2025 against 1961 to 1990

Over 2010 to 2025, Wongan Hills had a mean temperature of 19.4 C (66.8 F) and 370.1 mm (14.6 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Carnamah (Australia, 156 km away), Morawa (Australia, 199 km away) and Bencubbin (Australia, 109 km away).

Climate twins of Wongan Hills: stations whose 1961 to 1990 climate is closest to its 2010 to 2025 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Carnamah	Australia	156 km (97 mi)	19.6 C (67.3 F)	383.1 mm (15.1 in)	0.47
Morawa	Australia	199 km (124 mi)	20.1 C (68.1 F)	332.1 mm (13.1 in)	0.82
Bencubbin	Australia	109 km (68 mi)	18.5 C (65.3 F)	332.3 mm (13.1 in)	0.89

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.
