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

54 years with a frost

Across 54 years with a frost, the median last spring frost at St John Bethlehem Aca falls on 21 April and the median first autumn frost on 18 October, which leaves a median of 184 days between them.

Fitted over all years, the growing season changes by +0.6 days per decade at this station.

Frost dates and growing season at St John Bethlehem Aca
Measure	Median, all years	Earliest period	Recent period (1921 to 1957)	Recent against earliest	Fitted trend
Last spring frost	21 April	n/a	21 April	n/a	+0.5 days per decade
First autumn frost	18 October	n/a	20 October	n/a	+1.1 days per decade
Growing days	184 days	n/a	185 days	n/a	+0.6 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

62 years, 1897 to 1958

A day with at least 64.4 mm (2.5 in) of rain is expected about once in 2 years. A day with at least 118.7 mm (4.7 in) of rain is expected about once in 100 years.

Rainfall return levels at St John Bethlehem Aca: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	64.4 mm (2.5 in)
5 years	79.1 mm (3.1 in)
10 years	88.8 mm (3.5 in)
25 years	100.9 mm (4.0 in)
50 years	109.8 mm (4.3 in)
100 years	118.7 mm (4.7 in)	Longer than the 62 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, 62 years of values from 1897 to 1958.

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: 119.4 mm (4.7 in) in 1909; 104.1 mm (4.1 in) in 1937; 101.6 mm (4.0 in) in 1933.
