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
59 years with a frost
Across 59 years with a frost, the median last spring frost at Fraser falls on 30 June and the median first autumn frost on 1 July, which leaves a median of 2 days between them.
Fitted over all years, the growing season changes by -0.1 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.
Rainfall Return Levels
62 years, 1910 to 1973
A day with at least 25.1 mm (1.0 in) of rain is expected about once in 2 years. A day with at least 78.5 mm (3.1 in) of rain is expected about once in 100 years.

Longer than the 62 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, 62 years of values from 1910 to 1973.
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: 81.3 mm (3.2 in) in 1959; 63.5 mm (2.5 in) in 1957; 58.4 mm (2.3 in) in 1916.
Station Changes
2 suspected
2 changes were suspected in the annual mean temperature of Fraser, at 1940 and 1955. Each is measured against neighbouring stations.
Relative to 5 neighbouring stations, the station's annual mean temperature from 1940 ran 0.7 C (1.2 F) higher than in the years before (likely change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 1955 ran 0.9 C (1.7 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.
