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

71 years with a frost

Across 71 years with a frost, the median last spring frost at Richmond falls on 15 April and the median first autumn frost on 25 October, which leaves a median of 189 days between them.

In 1947 to 1976 the median growing season was 184 days. That is 12 days fewer than in 1897 to 1932.

Fitted over all years, the growing season changes by -1.7 days per decade at this station.

Frost dates and growing season at Richmond
Measure	Median, all years	Earliest period (1897 to 1932)	Recent period (1947 to 1976)	Recent against earliest	Fitted trend
Last spring frost	15 April	11 April	20 April	9 days later	+1.5 days per decade
First autumn frost	25 October	27 October	21 October	6 days earlier	-0.2 days per decade
Growing days	189 days	196 days	184 days	12 days fewer	-1.7 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

72 years, 1897 to 1976

A day with at least 60.5 mm (2.4 in) of rain is expected about once in 2 years. A day with at least 141.0 mm (5.6 in) of rain is expected about once in 100 years.

Rainfall return levels at Richmond: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	60.5 mm (2.4 in)
5 years	77.1 mm (3.0 in)
10 years	89.8 mm (3.5 in)
25 years	108.3 mm (4.3 in)
50 years	123.8 mm (4.9 in)
100 years	141.0 mm (5.6 in)	Longer than the 72 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, 72 years of values from 1897 to 1976.

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: 180.8 mm (7.1 in) in 1959; 156.7 mm (6.2 in) in 1932; 97.8 mm (3.9 in) in 1909.

1964	+0.2	+0.4	likely	5

Possible change at the station (a move, a new instrument or a new site); the record is kept as measured. A "likely" change has a larger test statistic than a "possible" one. Neither says why the station differs from its neighbours. How changes are found, and the largest ones.
