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

77 years with a frost

Across 77 years with a frost, the median last spring frost at Bird Island falls on 8 May and the median first autumn frost on 29 September, which leaves a median of 146 days between them.

In 1943 to 1974 the median growing season was 152 days. That is 14 days more than in 1894 to 1925.

Fitted over all years, the growing season changes by +2.5 days per decade at this station.

Frost dates and growing season at Bird Island
Measure	Median, all years	Earliest period (1894 to 1925)	Recent period (1943 to 1974)	Recent against earliest	Fitted trend
Last spring frost	8 May	12 May	6 May	6 days earlier	-1.1 days per decade
First autumn frost	29 September	27 September	1 October	4 days later	+1.4 days per decade
Growing days	146 days	138 days	152 days	14 days more	+2.5 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

79 years, 1894 to 1975

A day with at least 51.8 mm (2.0 in) of rain is expected about once in 2 years. A day with at least 129.3 mm (5.1 in) of rain is expected about once in 100 years.

Rainfall return levels at Bird Island: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	51.8 mm (2.0 in)
5 years	69.2 mm (2.7 in)
10 years	81.9 mm (3.2 in)
25 years	99.6 mm (3.9 in)
50 years	114.0 mm (4.5 in)
100 years	129.3 mm (5.1 in)	Longer than the 79 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, 79 years of values from 1894 to 1975.

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: 112.3 mm (4.4 in) in 1900; 112.0 mm (4.4 in) in 1948; 107.2 mm (4.2 in) in 1973.
