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 Norwood falls on 8 June and the median first autumn frost on 20 September, which leaves a median of 108 days between them.
In 1975 to 2007 the median growing season was 112 days. That is 4 days more than in 1929 to 1968.
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
70 years, 1933 to 2007
A day with at least 26.8 mm (1.1 in) of rain is expected about once in 2 years. A day with at least 62.9 mm (2.5 in) of rain is expected about once in 100 years.

Longer than the 70 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, 70 years of values from 1933 to 2007.
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: 73.7 mm (2.9 in) in 1996; 50.8 mm (2.0 in) in 1942; 47.2 mm (1.9 in) in 1989.
Station Changes
1 suspected
One change was suspected in the annual mean temperature of Norwood, at 1975. Each is measured against neighbouring stations.
Relative to 5 neighbouring stations, the station's annual mean temperature from 1975 ran 0.4 C (0.7 F) higher 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.
