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

54 years with a frost

Across 54 years with a frost, the median last spring frost at Lake Eildon falls on 2 September and the median first autumn frost on 3 June, which leaves a median of 277 days between them.

Fitted over all years, the growing season changes by +6.2 days per decade at this station.

Frost dates and growing season at Lake Eildon
Measure	Median, all years	Earliest period	Recent period (1995 to 2025)	Recent against earliest	Fitted trend
Last spring frost	2 September	n/a	28 August	n/a	-3.1 days per decade
First autumn frost	3 June	n/a	7 June	n/a	+3.1 days per decade
Growing days	277 days	n/a	292 days	n/a	+6.2 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

135 years, 1888 to 2025

A day with at least 45.2 mm (1.8 in) of rain is expected about once in 2 years. A day with at least 110.7 mm (4.4 in) of rain is expected about once in 100 years.

Rainfall return levels at Lake Eildon: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	45.2 mm (1.8 in)
5 years	61.0 mm (2.4 in)
10 years	72.1 mm (2.8 in)
25 years	87.0 mm (3.4 in)
50 years	98.6 mm (3.9 in)
100 years	110.7 mm (4.4 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 135 years of values from 1888 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: 148.6 mm (5.9 in) in 2017; 108.0 mm (4.3 in) in 2023; 101.3 mm (4.0 in) in 1950.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Lake Eildon, at 1998. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1998 ran 0.1 C (0.2 F) higher than in the years before (possible change).

Year	Shift (C)	Shift (F)	Strength	Neighbours
1998	+0.1	+0.2	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, Lake Eildon had a mean temperature of 14.8 C (58.6 F) and 836.9 mm (32.9 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Adelong Post Office (Australia, 288 km away), Applethorpe (Australia, 1,110 km away) and Stanthorpe Leslie Parade (Australia, 1,106 km away).

Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Applethorpe	Australia	1,110 km (690 mi)	14.6 C (58.3 F)	809.6 mm (31.9 in)	0.75
Adelong Post Office	Australia	288 km (179 mi)	14.3 C (57.8 F)	831.5 mm (32.7 in)	0.75
Stanthorpe Leslie Parade	Australia	1,106 km (687 mi)	15.2 C (59.4 F)	804.5 mm (31.7 in)	0.84

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.
