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

68 years with a frost

Across 68 years with a frost, the median last spring frost at Harrison falls on 15 April and the median first autumn frost on 18 October, which leaves a median of 188 days between them.

In 1952 to 2025 the median growing season was 190 days. That is 11 days more than in 1900 to 1942.

Fitted over all years, the growing season changes by +3.0 days per decade at this station.

First autumn frost18 October17 October19 October2 days later+1.4 days per decade
Growing days188 days179 days190 days11 days more+3.0 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

81 years, 1892 to 2025

A day with at least 76.3 mm (3.0 in) of rain is expected about once in 2 years. A day with at least 172.5 mm (6.8 in) of rain is expected about once in 100 years.

100 years172.5 mm (6.8 in)Longer than the 81 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, 81 years of values from 1892 to 2025.

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: 141.5 mm (5.6 in) in 2008; 141.0 mm (5.6 in) in 1946; 136.4 mm (5.4 in) in 1935.
