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 frost

Across 68 years with a frost, the median last spring frost at Sydney falls on 29 May and the median first autumn frost on 13 October, which leaves a median of 139 days between them.

In 1911 to 1940 the median growing season was 145 days. That is 10 days more than in 1870 to 1902.

Fitted over all years, the growing season changes by +3.1 days per decade at this station.

Frost dates and growing season at Sydney
Measure	Median, all years	Earliest period (1870 to 1902)	Recent period (1911 to 1940)	Recent against earliest	Fitted trend
Last spring frost	29 May	1 June	24 May	8 days earlier	-0.9 days per decade
First autumn frost	13 October	8 October	17 October	9 days later	+2.1 days per decade
Growing days	139 days	135 days	145 days	10 days more	+3.1 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

68 years, 1870 to 1940

A day with at least 56.6 mm (2.2 in) of rain is expected about once in 2 years. A day with at least 109.9 mm (4.3 in) of rain is expected about once in 100 years.

Rainfall return levels at Sydney: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	56.6 mm (2.2 in)
5 years	70.5 mm (2.8 in)
10 years	79.8 mm (3.1 in)
25 years	91.8 mm (3.6 in)
50 years	100.8 mm (4.0 in)
100 years	109.9 mm (4.3 in)	Longer than the 68 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, 68 years of values from 1870 to 1940.

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: 97.8 mm (3.9 in) in 1890; 95.8 mm (3.8 in) in 1883; 88.9 mm (3.5 in) in 1940.
