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
66 years with a frost
Across 66 years with a frost, the median last spring frost at Sugarloaf Rsvr falls on 22 June and the median first autumn frost on 9 August, which leaves a median of 49 days between them.
In 1994 to 2025 the median growing season was 63 days. That is 34 days more than in 1901 to 1986.
Fitted over all years, the growing season changes by +0.7 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
41 years, 1901 to 2010
A day with at least 24.8 mm (1.0 in) of rain is expected about once in 2 years. A day with at least 57.6 mm (2.3 in) of rain is expected about once in 100 years.

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 41 years of values from 1901 to 2010.
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: 53.3 mm (2.1 in) in 1901; 47.0 mm (1.9 in) in 2008; 42.2 mm (1.7 in) in 1903.
Station Changes
