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

84 years with a frost

Across 84 years with a frost, the median last spring frost at Poplar 2 E falls on 14 May and the median first autumn frost on 18 September, which leaves a median of 124 days between them.

In 1955 to 1990 the median growing season was 129 days. That is 2 days more than in 1896 to 1929.

Fitted over all years, the growing season changes by +0.9 days per decade at this station.

Frost dates and growing season at Poplar 2 E
Measure	Median, all years	Earliest period (1896 to 1929)	Recent period (1955 to 1990)	Recent against earliest	Fitted trend
Last spring frost	14 May	15 May	13 May	2 days earlier	0.0 days per decade
First autumn frost	18 September	16 September	20 September	4 days later	+0.9 days per decade
Growing days	124 days	127 days	129 days	2 days more	+0.9 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, 1896 to 1990

A day with at least 37.2 mm (1.5 in) of rain is expected about once in 2 years. A day with at least 91.7 mm (3.6 in) of rain is expected about once in 100 years.

Rainfall return levels at Poplar 2 E: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	37.2 mm (1.5 in)
5 years	50.6 mm (2.0 in)
10 years	59.9 mm (2.4 in)
25 years	72.3 mm (2.8 in)
50 years	81.9 mm (3.2 in)
100 years	91.7 mm (3.6 in)	Longer than the 85 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, 85 years of values from 1896 to 1990.

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: 108.2 mm (4.3 in) in 1976; 77.5 mm (3.1 in) in 1966; 72.4 mm (2.9 in) in 1921.
