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

32 years with a frost

Across 32 years with a frost, the median last spring frost at Narrabri West Post Office falls on 20 August and the median first autumn frost on 22 June, which leaves a median of 311 days between them.

Fitted over all years, the growing season changes by +4.7 days per decade at this station.

Frost dates and growing season at Narrabri West Post Office
Measure	Median, all years	Earliest period	Recent period (1965 to 2001)	Recent against earliest	Fitted trend
Last spring frost	20 August	n/a	19 August	n/a	-2.1 days per decade
First autumn frost	22 June	n/a	23 June	n/a	+2.6 days per decade
Growing days	311 days	n/a	312 days	n/a	+4.7 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

83 years, 1892 to 2013

A day with at least 63.4 mm (2.5 in) of rain is expected about once in 2 years. A day with at least 162.8 mm (6.4 in) of rain is expected about once in 100 years.

Rainfall return levels at Narrabri West 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	63.4 mm (2.5 in)
5 years	85.4 mm (3.4 in)
10 years	101.7 mm (4.0 in)
25 years	124.4 mm (4.9 in)
50 years	142.9 mm (5.6 in)
100 years	162.8 mm (6.4 in)	Longer than the 83 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, 83 years of values from 1892 to 2013.

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: 135.4 mm (5.3 in) in 1974; 134.0 mm (5.3 in) in 1997; 129.0 mm (5.1 in) in 1908.
