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

39 years with a frost

Across 39 years with a frost, the median last spring frost at Sevenmile Marsh falls on 16 June and the median first autumn frost on 26 September, which leaves a median of 103 days between them.

Fitted over all years, the growing season changes by +19.4 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.

Rainfall Return Levels

45 years, 1981 to 2025

A day with at least 71.2 mm (2.8 in) of rain is expected about once in 2 years. A day with at least 191.0 mm (7.5 in) of rain is expected about once in 100 years.

100 years191.0 mm (7.5 in)Longer than the 45 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, 45 years of values from 1981 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: 172.7 mm (6.8 in) in 1983; 160.0 mm (6.3 in) in 2004; 152.4 mm (6.0 in) in 2014.
