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

80 years with a frost

Across 80 years with a frost, the median last spring frost at Holbrook falls on 7 May and the median first autumn frost on 15 October, which leaves a median of 164 days between them.

In 1964 to 2009 the median growing season was 164 days. That is 5 days more than in 1894 to 1939.

Fitted over all years, the growing season changes by +0.5 days per decade at this station.

Frost dates and growing season at Holbrook
Measure	Median, all years	Earliest period (1894 to 1939)	Recent period (1964 to 2009)	Recent against earliest	Fitted trend
Last spring frost	7 May	7 May	8 May	1 day later	-0.4 days per decade
First autumn frost	15 October	12 October	14 October	2 days later	+0.1 days per decade
Growing days	164 days	159 days	164 days	5 days more	+0.5 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

102 years, 1893 to 2009

A day with at least 23.9 mm (0.9 in) of rain is expected about once in 2 years. A day with at least 64.1 mm (2.5 in) of rain is expected about once in 100 years.

Rainfall return levels at Holbrook: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	23.9 mm (0.9 in)
5 years	33.3 mm (1.3 in)
10 years	40.1 mm (1.6 in)
25 years	49.2 mm (1.9 in)
50 years	56.4 mm (2.2 in)
100 years	64.1 mm (2.5 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 102 years of values from 1893 to 2009.

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: 71.1 mm (2.8 in) in 1925; 63.5 mm (2.5 in) in 1987; 54.6 mm (2.1 in) in 1895.
