The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 62 years of values from 1956 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: 196.0 mm (7.7 in) in 1999; 182.0 mm (7.2 in) in 1992; 160.8 mm (6.3 in) in 1960.

Climate Twins

2008 to 2025 against 1961 to 1990

Over 2008 to 2025, Montague Island Lighthouse had a mean temperature of 17.2 C (62.9 F) and 769.9 mm (30.3 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Esperance (Australia, 2,584 km away), Cape Naturaliste (Australia, 3,208 km away) and Bunbury Post Office (Australia, 3,159 km away).

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.
