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

43 years with a frost

Across 43 years with a frost, the median last spring frost at Longerenong falls on 9 October and the median first autumn frost on 21 May, which leaves a median of 245 days between them.

Fitted over all years, the growing season changes by -15.2 days per decade at this station.

Frost dates and growing season at Longerenong
Measure	Median, all years	Earliest period	Recent period (1993 to 2025)	Recent against earliest	Fitted trend
Last spring frost	9 October	n/a	17 October	n/a	+12.4 days per decade
First autumn frost	21 May	n/a	17 May	n/a	-2.8 days per decade
Growing days	245 days	n/a	219 days	n/a	-15.2 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

125 years, 1863 to 2025

A day with at least 34.5 mm (1.4 in) of rain is expected about once in 2 years. A day with at least 99.1 mm (3.9 in) of rain is expected about once in 100 years.

Rainfall return levels at Longerenong: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	34.5 mm (1.4 in)
5 years	48.5 mm (1.9 in)
10 years	59.0 mm (2.3 in)
25 years	73.7 mm (2.9 in)
50 years	85.9 mm (3.4 in)
100 years	99.1 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, 125 years of values from 1863 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: 106.7 mm (4.2 in) in 1957; 97.0 mm (3.8 in) in 2011; 91.9 mm (3.6 in) in 1973.

Station Changes

3 suspected

3 changes were suspected in the annual mean temperature of Longerenong, at 1982, 1999 and 2014. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1982 ran 0.2 C (0.3 F) higher than in the years before (likely change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 1999 ran 0.3 C (0.5 F) lower than in the years before (likely change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 2014 ran 0.1 C (0.2 F) higher than in the years before (likely change).

Suspected changes in the annual mean temperature at Longerenong, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1982	+0.2	+0.3	likely	5
1999	-0.2	-0.4	likely	5
2014	+0.1	+0.2	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

2010 to 2025 against 1961 to 1990

Over 2010 to 2025, Longerenong had a mean temperature of 15.1 C (59.2 F) and 404.7 mm (15.9 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Kyabram Dpi (Australia, 250 km away), Tatura Inst Sustainable Ag (Australia, 266 km away) and Eudunda (Australia, 402 km away).

Climate twins of Longerenong: 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
Kyabram Dpi	Australia	250 km (155 mi)	14.8 C (58.6 F)	458.6 mm (18.1 in)	0.55
Tatura Inst Sustainable Ag	Australia	266 km (165 mi)	14.8 C (58.6 F)	480.4 mm (18.9 in)	0.60
Eudunda	Australia	402 km (250 mi)	14.9 C (58.9 F)	460.7 mm (18.1 in)	0.65

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.
