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

47 years with a frost

Across 47 years with a frost, the median last spring frost at College STN 6 SW falls on 7 March and the median first autumn frost on 22 November, which leaves a median of 268 days between them.

Fitted over all years, the growing season changes by +1.5 days per decade at this station.

Frost dates and growing season at College STN 6 SW
Measure	Median, all years	Earliest period	Recent period (1923 to 1956)	Recent against earliest	Fitted trend
Last spring frost	7 March	n/a	5 March	n/a	-2.2 days per decade
First autumn frost	22 November	n/a	23 November	n/a	-0.7 days per decade
Growing days	268 days	n/a	274 days	n/a	+1.5 days per decade

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

57 years, 1889 to 1982

A day with at least 85.4 mm (3.4 in) of rain is expected about once in 2 years. A day with at least 213.5 mm (8.4 in) of rain is expected about once in 100 years.

Rainfall return levels at College STN 6 SW: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	85.4 mm (3.4 in)
5 years	113.4 mm (4.5 in)
10 years	134.2 mm (5.3 in)
25 years	163.5 mm (6.4 in)
50 years	187.5 mm (7.4 in)
100 years	213.5 mm (8.4 in)	Longer than the 57 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, 57 years of values from 1889 to 1982.

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: 199.1 mm (7.8 in) in 1889; 191.5 mm (7.5 in) in 1913; 170.2 mm (6.7 in) in 1905.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of College STN 6 SW, at 1918. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1918 ran 0.5 C (0.9 F) lower than in the years before (likely change).

Year	Shift (C)	Shift (F)	Strength	Neighbours
1918	-0.5	-0.9	likely	5

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.
