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

64 years with a frost

Across 64 years with a frost, the median last spring frost at Centennial 1NE falls on 11 June and the median first autumn frost on 9 September, which leaves a median of 89 days between them.

In 1957 to 2002 the median growing season was 85 days. That is 8 days fewer than in 1900 to 1951.

Fitted over all years, the growing season changes by -0.9 days per decade at this station.

Frost dates and growing season at Centennial 1NE
Measure	Median, all years	Earliest period (1900 to 1951)	Recent period (1957 to 2002)	Recent against earliest	Fitted trend
Last spring frost	11 June	9 June	16 June	7 days later	+0.8 days per decade
First autumn frost	9 September	10 September	6 September	4 days earlier	-0.1 days per decade
Growing days	89 days	93 days	85 days	8 days fewer	-0.9 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

65 years, 1900 to 2004

A day with at least 24.0 mm (0.9 in) of rain is expected about once in 2 years. A day with at least 55.4 mm (2.2 in) of rain is expected about once in 100 years.

Rainfall return levels at Centennial 1NE: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	24.0 mm (0.9 in)
5 years	31.7 mm (1.2 in)
10 years	37.0 mm (1.5 in)
25 years	44.1 mm (1.7 in)
50 years	49.7 mm (2.0 in)
100 years	55.4 mm (2.2 in)	Longer than the 65 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, 65 years of values from 1900 to 2004.

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: 51.1 mm (2.0 in) in 1965; 45.7 mm (1.8 in) in 1900; 45.7 mm (1.8 in) in 1912.
