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

20 years with a frost

Across 20 years with a frost, the median last spring frost at J.G.H. van der Wath Airp falls on 31 July and the median first autumn frost on 30 June, which leaves a median of 335 days between them.

Frost dates and growing season at J.G.H. van der Wath Airp
Measure	Median, all years	Earliest period	Recent period (1971 to 2002)	Recent against earliest	Fitted trend
Last spring frost	31 July	n/a	31 July	n/a	n/a
First autumn frost	30 June	n/a	30 June	n/a	n/a
Growing days	335 days	n/a	335 days	n/a	n/a

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

54 years, 1949 to 2003

A day with at least 29.2 mm (1.1 in) of rain is expected about once in 2 years. A day with at least 106.5 mm (4.2 in) of rain is expected about once in 100 years.

Rainfall return levels at J.G.H. van der Wath Airp: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	29.2 mm (1.1 in)
5 years	47.3 mm (1.9 in)
10 years	60.2 mm (2.4 in)
25 years	77.8 mm (3.1 in)
50 years	91.8 mm (3.6 in)
100 years	106.5 mm (4.2 in)	Longer than the 54 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, 54 years of values from 1949 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: 100.0 mm (3.9 in) in 1957; 74.0 mm (2.9 in) in 1993; 72.0 mm (2.8 in) in 1974.
