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

49 years with a frost

Across 49 years with a frost, the median last spring frost at Weston 2 SE falls on 30 April and the median first autumn frost on 10 October, which leaves a median of 155 days between them.

Fitted over all years, the growing season changes by +13.0 days per decade at this station.

Frost dates and growing season at Weston 2 SE
Measure	Median, all years	Earliest period	Recent period (1917 to 1953)	Recent against earliest	Fitted trend
Last spring frost	30 April	n/a	25 April	n/a	-6.8 days per decade
First autumn frost	10 October	n/a	22 October	n/a	+6.2 days per decade
Growing days	155 days	n/a	180 days	n/a	+13.0 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

52 years, 1896 to 1953

A day with at least 29.2 mm (1.1 in) of rain is expected about once in 2 years. A day with at least 90.5 mm (3.6 in) of rain is expected about once in 100 years.

Rainfall return levels at Weston 2 SE: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	29.2 mm (1.1 in)
5 years	39.9 mm (1.6 in)
10 years	48.8 mm (1.9 in)
25 years	62.8 mm (2.5 in)
50 years	75.5 mm (3.0 in)
100 years	90.5 mm (3.6 in)	Longer than the 52 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, 52 years of values from 1896 to 1953.

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: 117.1 mm (4.6 in) in 1906; 70.6 mm (2.8 in) in 1921; 52.1 mm (2.1 in) in 1899.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Weston 2 SE, at 1928 and 1941. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1928 ran 0.8 C (1.4 F) higher than in the years before (likely change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 1941 ran 0.5 C (0.9 F) lower than in the years before (possible change).

Suspected changes in the annual mean temperature at Weston 2 SE, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1928	+0.8	+1.4	likely	5
1941	-0.5	-0.9	possible	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.
