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
91 years with a frost
Across 91 years with a frost, the median last spring frost at Flora 5 NW falls on 15 April and the median first autumn frost on 14 October, which leaves a median of 181 days between them.
In 1977 to 2008 the median growing season was 174 days. That is 8 days fewer than in 1894 to 1938.
Fitted over all years, the growing season changes by -0.5 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
104 years, 1894 to 2008
A day with at least 66.4 mm (2.6 in) of rain is expected about once in 2 years. A day with at least 158.6 mm (6.2 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, 104 years of values from 1894 to 2008.
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: 177.8 mm (7.0 in) in 2006; 145.0 mm (5.7 in) in 1904; 135.4 mm (5.3 in) in 1912.
