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

35 years with a frost

Across 35 years with a frost, the median last spring frost at Clover Valley falls on 8 June and the median first autumn frost on 11 September, which leaves a median of 96 days between them.

Fitted over all years, the growing season changes by +2.8 days per decade at this station.

Frost dates and growing season at Clover Valley
Measure	Median, all years	Earliest period	Recent period (1910 to 2003)	Recent against earliest	Fitted trend
Last spring frost	8 June	n/a	7 June	n/a	-0.4 days per decade
First autumn frost	11 September	n/a	11 September	n/a	+2.4 days per decade
Growing days	96 days	n/a	98 days	n/a	+2.8 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

50 years, 1900 to 2003

A day with at least 28.8 mm (1.1 in) of rain is expected about once in 2 years. A day with at least 92.6 mm (3.6 in) of rain is expected about once in 100 years.

Rainfall return levels at Clover Valley: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	28.8 mm (1.1 in)
5 years	42.7 mm (1.7 in)
10 years	53.0 mm (2.1 in)
25 years	67.6 mm (2.7 in)
50 years	79.6 mm (3.1 in)
100 years	92.6 mm (3.6 in)	Longer than the 50 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, 50 years of values from 1900 to 2003.

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: 76.7 mm (3.0 in) in 1979; 74.9 mm (2.9 in) in 1909; 62.0 mm (2.4 in) in 1903.
