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
80 years with a frost
Across 80 years with a frost, the median last spring frost at Ashland Exp Farm falls on 31 May and the median first autumn frost on 19 September, which leaves a median of 109 days between them.
In 1963 to 1993 the median growing season was 109 days. The two periods have the same number of growing days.
Fitted over all years, the growing season changes by +1.1 days per decade at this station.

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.

Longer than the 80 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, 80 years of values from 1901 to 2021.
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: 162.3 mm (6.4 in) in 1946; 124.5 mm (4.9 in) in 1909; 124.5 mm (4.9 in) in 1941.
