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
96 years with a frost
Across 96 years with a frost, the median last spring frost at Parry Sound falls on 15 May and the median first autumn frost on 1 October, which leaves a median of 137 days between them.
In 1943 to 1975 the median growing season was 136 days. That is 1 day more than in 1876 to 1905.
Fitted over all years, the growing season changes by +0.9 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
101 years, 1875 to 1975
A day with at least 44.1 mm (1.7 in) of rain is expected about once in 2 years. A day with at least 105.0 mm (4.1 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, 101 years of values from 1875 to 1975.
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: 123.4 mm (4.9 in) in 1956; 108.7 mm (4.3 in) in 1901; 83.3 mm (3.3 in) in 1878.
Station Changes
1 suspected
One change was suspected in the annual mean temperature of Parry Sound, at 1953. Each is measured against neighbouring stations.
Relative to 5 neighbouring stations, the station's annual mean temperature from 1953 ran 0.3 C (0.5 F) lower than in the years before (likely change).

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.
