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

83 years with a frost

Across 83 years with a frost, the median last spring frost at White River falls on 20 June and the median first autumn frost on 28 July, which leaves a median of 38 days between them.

In 1945 to 1975 the median growing season was 45 days. That is 15 days more than in 1889 to 1921.

Fitted over all years, the growing season changes by +2.3 days per decade at this station.

Frost dates and growing season at White River
Measure	Median, all years	Earliest period (1889 to 1921)	Recent period (1945 to 1975)	Recent against earliest	Fitted trend
Last spring frost	20 June	22 June	19 June	3 days earlier	-0.7 days per decade
First autumn frost	28 July	23 July	3 August	11 days later	+1.6 days per decade
Growing days	38 days	30 days	45 days	15 days more	+2.3 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

85 years, 1889 to 1975

A day with at least 37.8 mm (1.5 in) of rain is expected about once in 2 years. A day with at least 91.9 mm (3.6 in) of rain is expected about once in 100 years.

2 years	37.8 mm (1.5 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 85 years of values from 1889 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: 91.9 mm (3.6 in) in 1941; 76.5 mm (3.0 in) in 1937; 74.7 mm (2.9 in) in 1891.
