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

70 years with a frost

Across 70 years with a frost, the median last spring frost at Paterson falls on 13 April and the median first autumn frost on 28 October, which leaves a median of 197 days between them.

In 1938 to 1973 the median growing season was 206 days. That is 9 days more than in 1894 to 1924.

Fitted over all years, the growing season changes by +2.0 days per decade at this station.

Frost dates and growing season at Paterson
Measure	Median, all years	Earliest period (1894 to 1924)	Recent period (1938 to 1973)	Recent against earliest	Fitted trend
Last spring frost	13 April	12 April	13 April	1 day later	-0.5 days per decade
First autumn frost	28 October	26 October	31 October	5 days later	+1.5 days per decade
Growing days	197 days	197 days	206 days	9 days more	+2.0 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

83 years, 1866 to 1973

A day with at least 70.7 mm (2.8 in) of rain is expected about once in 2 years. A day with at least 213.4 mm (8.4 in) of rain is expected about once in 100 years.

Rainfall return levels at Paterson: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	70.7 mm (2.8 in)
5 years	94.3 mm (3.7 in)
10 years	114.5 mm (4.5 in)
25 years	146.8 mm (5.8 in)
50 years	177.0 mm (7.0 in)
100 years	213.4 mm (8.4 in)	Longer than the 83 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, 83 years of values from 1866 to 1973.

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: 290.8 mm (11.4 in) in 1903; 176.5 mm (6.9 in) in 1971; 140.7 mm (5.5 in) in 1966.
