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
78 years with a frost
Across 78 years with a frost, the median last spring frost at Belvidere falls on 30 April and the median first autumn frost on 13 October, which leaves a median of 167 days between them.
In 1949 to 1980 the median growing season was 167 days. That is 3 days more than in 1894 to 1927.
Fitted over all years, the growing season changes by +0.4 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
88 years, 1892 to 1981
A day with at least 63.1 mm (2.5 in) of rain is expected about once in 2 years. A day with at least 170.3 mm (6.7 in) of rain is expected about once in 100 years.

Longer than the 88 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, 88 years of values from 1892 to 1981.
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: 168.1 mm (6.6 in) in 1951; 139.2 mm (5.5 in) in 1896; 134.6 mm (5.3 in) in 1913.
Station Changes
1 suspected
One change was suspected in the annual mean temperature of Belvidere, at 1926. Each is measured against neighbouring stations.
Relative to 5 neighbouring stations, the station's annual mean temperature from 1926 ran 0.2 C (0.4 F) higher than in the years before (possible 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.
