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

25 years with a frost

Across 25 years with a frost, the median last spring frost at White Cliffs Post Office falls on 25 July and the median first autumn frost on 6 July, which leaves a median of 337 days between them.

Fitted over all years, the growing season changes by +3.5 days per decade at this station.

Frost dates and growing season at White Cliffs Post Office
Measure	Median, all years	Earliest period	Recent period (1962 to 2009)	Recent against earliest	Fitted trend
Last spring frost	25 July	n/a	25 July	n/a	-0.3 days per decade
First autumn frost	6 July	n/a	6 July	n/a	+3.2 days per decade
Growing days	337 days	n/a	337 days	n/a	+3.5 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

107 years, 1901 to 2011

A day with at least 37.6 mm (1.5 in) of rain is expected about once in 2 years. A day with at least 144.0 mm (5.7 in) of rain is expected about once in 100 years.

Rainfall return levels at White Cliffs 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	37.6 mm (1.5 in)
5 years	56.8 mm (2.2 in)
10 years	72.6 mm (2.9 in)
25 years	96.9 mm (3.8 in)
50 years	118.7 mm (4.7 in)
100 years	144.0 mm (5.7 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 107 years of values from 1901 to 2011.

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: 140.2 mm (5.5 in) in 1971; 122.7 mm (4.8 in) in 1932; 111.0 mm (4.4 in) in 1993.
