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

51 years with a frost

Across 51 years with a frost, the median last spring frost at Tambo Post Office falls on 23 August and the median first autumn frost on 12 June, which leaves a median of 286 days between them.

Fitted over all years, the growing season changes by +3.2 days per decade at this station.

Frost dates and growing season at Tambo Post Office
Measure	Median, all years	Earliest period	Recent period (1990 to 2022)	Recent against earliest	Fitted trend
Last spring frost	23 August	n/a	18 August	n/a	-4.3 days per decade
First autumn frost	12 June	n/a	10 June	n/a	-1.1 days per decade
Growing days	286 days	n/a	289 days	n/a	+3.2 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

138 years, 1888 to 2025

A day with at least 59.7 mm (2.4 in) of rain is expected about once in 2 years. A day with at least 152.9 mm (6.0 in) of rain is expected about once in 100 years.

Rainfall return levels at Tambo Post Office: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	59.7 mm (2.4 in)
5 years	83.3 mm (3.3 in)
10 years	99.5 mm (3.9 in)
25 years	120.5 mm (4.7 in)
50 years	136.6 mm (5.4 in)
100 years	152.9 mm (6.0 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 138 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: 172.7 mm (6.8 in) in 1910; 164.0 mm (6.5 in) in 2018; 161.5 mm (6.4 in) in 2025.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Tambo Post Office, at 1967 and 2011. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1967 ran 0.2 C (0.3 F) higher than in the years before (possible change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 2011 ran 0.2 C (0.4 F) lower than in the years before (likely change).

Suspected changes in the annual mean temperature at Tambo Post Office, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1967	+0.2	+0.3	possible	5
2011	-0.2	-0.4	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

2008 to 2023 against 1961 to 1990

Over 2008 to 2023, Tambo Post Office had a mean temperature of 21.4 C (70.5 F) and 551.0 mm (21.7 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are St George Post Office (Australia, 420 km away), Roma Post Office (Australia, 316 km away) and Taroom Post Office (Australia, 366 km away).

Climate twins of Tambo Post Office: stations whose 1961 to 1990 climate is closest to its 2008 to 2023 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
St George Post Office	Australia	420 km (261 mi)	20.8 C (69.4 F)	539.2 mm (21.2 in)	0.88
Roma Post Office	Australia	316 km (196 mi)	20.6 C (69.0 F)	630.8 mm (24.8 in)	1.02
Taroom Post Office	Australia	366 km (227 mi)	20.7 C (69.2 F)	677.1 mm (26.7 in)	1.03

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.
