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

125 years, 1881 to 2023

A day with at least 37.6 mm (1.5 in) of rain is expected about once in 2 years. A day with at least 115.2 mm (4.5 in) of rain is expected about once in 100 years.

Rainfall return levels at Cape Bruny Lighthouse: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	37.6 mm (1.5 in)
5 years	52.6 mm (2.1 in)
10 years	64.5 mm (2.5 in)
25 years	82.2 mm (3.2 in)
50 years	97.7 mm (3.8 in)
100 years	115.2 mm (4.5 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 125 years of values from 1881 to 2023.

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: 136.4 mm (5.4 in) in 1934; 113.4 mm (4.5 in) in 1999; 91.9 mm (3.6 in) in 1916.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Cape Bruny Lighthouse, at 1990. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1990 ran 0.2 C (0.3 F) lower than in the years before (likely change).

Year	Shift (C)	Shift (F)	Strength	Neighbours
1990	-0.1	-0.3	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.

Climate Twins

2005 to 2020 against 1961 to 1990

Over 2005 to 2020, Cape Bruny Lighthouse had a mean temperature of 12.6 C (54.7 F) and 822.5 mm (32.4 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Orford (Aubin Court) (Australia, 120 km away), St Helens Post Office (Australia, 257 km away) and Quoiba (Australia, 262 km away).

Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Orford (Aubin Court)	Australia	120 km (75 mi)	12.6 C (54.8 F)	697.2 mm (27.4 in)	0.89
St Helens Post Office	Australia	257 km (160 mi)	12.9 C (55.3 F)	724.4 mm (28.5 in)	1.00
Quoiba	Australia	262 km (163 mi)	12.3 C (54.1 F)	968.7 mm (38.1 in)	1.04

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.
