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

69 years, 1952 to 2025

A day with at least 116.9 mm (4.6 in) of rain is expected about once in 2 years. A day with at least 293.9 mm (11.6 in) of rain is expected about once in 100 years.

Rainfall return levels at Ayr Dpi Research STN: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	116.9 mm (4.6 in)
5 years	169.1 mm (6.7 in)
10 years	201.7 mm (7.9 in)
25 years	240.6 mm (9.5 in)
50 years	267.9 mm (10.5 in)
100 years	293.9 mm (11.6 in)	Longer than the 69 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, 69 years of values from 1952 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: 327.8 mm (12.9 in) in 2020; 254.0 mm (10.0 in) in 1988; 234.7 mm (9.2 in) in 1955.

Climate Twins

2011 to 2025 against 1961 to 1990

Over 2011 to 2025, Ayr Dpi Research STN had a mean temperature of 24.2 C (75.5 F) and 936.1 mm (36.9 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Bowen Post Office (Australia, 102 km away), Pine Islet Lighthouse (Australia, 373 km away) and Inhambane (Mozambique, 11,204 km away).

Climate twins of Ayr Dpi Research STN: 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
Bowen Post Office	Australia	102 km (63 mi)	24.6 C (76.2 F)	939.9 mm (37.0 in)	0.46
Pine Islet Lighthouse	Australia	373 km (232 mi)	23.9 C (75.1 F)	864.1 mm (34.0 in)	0.46
Inhambane	Mozambique	11,204 km (6,962 mi)	23.8 C (74.8 F)	971.6 mm (38.3 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.
