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
68 years with a frostAcross 68 years with a frost, the median last spring frost at Ballarat Aerodrome falls on 9 October and the median first autumn frost on 11 May, which leaves a median of 209 days between them.
In 1996 to 2025 the median growing season was 209 days. That is 17 days fewer than in 1957 to 1987.
Fitted over all years, the growing season changes by -3.2 days per decade at this station.
| Measure | Median, all years | Earliest period (1957 to 1987) | Recent period (1996 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 9 October | 24 September | 10 October | 16 days later | +1.7 days per decade |
| First autumn frost | 11 May | 19 May | 12 May | 7 days earlier | -1.5 days per decade |
| Growing days | 209 days | 226 days | 209 days | 17 days fewer | -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
117 years, 1909 to 2025A day with at least 42.3 mm (1.7 in) of rain is expected about once in 2 years. A day with at least 103.3 mm (4.1 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 42.3 mm (1.7 in) | |
| 5 years | 57.9 mm (2.3 in) | |
| 10 years | 68.5 mm (2.7 in) | |
| 25 years | 82.3 mm (3.2 in) | |
| 50 years | 92.7 mm (3.6 in) | |
| 100 years | 103.3 mm (4.1 in) |
The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 117 years of values from 1909 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: 121.9 mm (4.8 in) in 1973; 106.7 mm (4.2 in) in 1933; 95.0 mm (3.7 in) in 2011.

Climate Twins
2011 to 2025 against 1961 to 1990Over 2011 to 2025, Ballarat Aerodrome had a mean temperature of 12.9 C (55.2 F) and 616.4 mm (24.3 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Mount Crawford Forest Headquar (Australia, 535 km away), Bathurst Gaol (Australia, 692 km away) and Bathurst Agricultural Station (Australia, 692 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Mount Crawford Forest Headquar | Australia | 535 km (332 mi) | 13.2 C (55.8 F) | 716.1 mm (28.2 in) | 0.64 |
| Bathurst Gaol | Australia | 692 km (430 mi) | 13.2 C (55.7 F) | 633.2 mm (24.9 in) | 0.90 |
| Bathurst Agricultural Station | Australia | 692 km (430 mi) | 13.0 C (55.4 F) | 654.0 mm (25.7 in) | 0.92 |
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.
