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

41 years with a frost

Across 41 years with a frost, the median last spring frost at Weismain falls on 5 May and the median first autumn frost on 12 October, which leaves a median of 152 days between them.

Fitted over all years, the growing season changes by +8.4 days per decade at this station.

Frost dates and growing season at Weismain
Measure	Median, all years	Earliest period	Recent period (1962 to 1991)	Recent against earliest	Fitted trend
Last spring frost	5 May	n/a	4 May	n/a	-2.9 days per decade
First autumn frost	12 October	n/a	18 October	n/a	+5.5 days per decade
Growing days	152 days	n/a	160 days	n/a	+8.4 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

49 years, 1941 to 1991

A day with at least 33.5 mm (1.3 in) of rain is expected about once in 2 years. A day with at least 77.4 mm (3.0 in) of rain is expected about once in 100 years.

Rainfall return levels at Weismain: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	33.5 mm (1.3 in)
5 years	43.7 mm (1.7 in)
10 years	51.0 mm (2.0 in)
25 years	61.0 mm (2.4 in)
50 years	69.0 mm (2.7 in)	Longer than the 49 years of record
100 years	77.4 mm (3.0 in)	Longer than the 49 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, 49 years of values from 1941 to 1991.

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: 65.3 mm (2.6 in) in 1968; 63.3 mm (2.5 in) in 1965; 62.4 mm (2.5 in) in 1988.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Weismain, at 1976. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1976 ran 0.1 C (0.1 F) lower than in the years before (possible change).

Suspected changes in the annual mean temperature at Weismain, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1976	-0.1	-0.1	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.
