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

30 years with a frost

Across 30 years with a frost, the median last spring frost at Lithgow (Birdwood St) falls on 11 October and the median first autumn frost on 30 April, which leaves a median of 214 days between them.

Fitted over all years, the growing season changes by +20.6 days per decade at this station.

Frost dates and growing season at Lithgow (Birdwood St)
Measure	Median, all years	Earliest period	Recent period (1966 to 2004)	Recent against earliest	Fitted trend
Last spring frost	11 October	n/a	11 October	n/a	-9.8 days per decade
First autumn frost	30 April	n/a	30 April	n/a	+10.9 days per decade
Growing days	214 days	n/a	214 days	n/a	+20.6 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

89 years, 1890 to 2005

A day with at least 64.6 mm (2.5 in) of rain is expected about once in 2 years. A day with at least 186.5 mm (7.3 in) of rain is expected about once in 100 years.

Rainfall return levels at Lithgow (Birdwood St): the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	64.6 mm (2.5 in)
5 years	91.6 mm (3.6 in)
10 years	111.6 mm (4.4 in)
25 years	139.4 mm (5.5 in)
50 years	162.1 mm (6.4 in)
100 years	186.5 mm (7.3 in)	Longer than the 89 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, 89 years of values from 1890 to 2005.

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: 179.0 mm (7.0 in) in 1975; 165.4 mm (6.5 in) in 1986; 163.8 mm (6.4 in) in 1922.
