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

62 years with a frost

Across 62 years with a frost, the median last spring frost at Pendleton Dwtn falls on 5 May and the median first autumn frost on 7 October, which leaves a median of 154 days between them.

In 1938 to 2016 the median growing season was 156 days. That is 7 days more than in 1895 to 1934.

Fitted over all years, the growing season changes by +1.3 days per decade at this station.

Frost dates and growing season at Pendleton Dwtn
Measure	Median, all years	Earliest period (1895 to 1934)	Recent period (1938 to 2016)	Recent against earliest	Fitted trend
Last spring frost	5 May	8 May	2 May	6 days earlier	-0.5 days per decade
First autumn frost	7 October	5 October	8 October	3 days later	+0.8 days per decade
Growing days	154 days	149 days	156 days	7 days more	+1.3 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, 1895 to 2013

A day with at least 21.8 mm (0.9 in) of rain is expected about once in 2 years. A day with at least 55.0 mm (2.2 in) of rain is expected about once in 100 years.

Rainfall return levels at Pendleton Dwtn: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	21.8 mm (0.9 in)
5 years	28.8 mm (1.1 in)
10 years	34.1 mm (1.3 in)
25 years	41.6 mm (1.6 in)
50 years	48.0 mm (1.9 in)	Longer than the 49 years of record
100 years	55.0 mm (2.2 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 1895 to 2013.

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: 50.8 mm (2.0 in) in 1912; 48.8 mm (1.9 in) in 1994; 41.7 mm (1.6 in) in 1906.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Pendleton Dwtn, at 1937. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1937 ran 0.3 C (0.5 F) lower than in the years before (possible change).

Suspected changes in the annual mean temperature at Pendleton Dwtn, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1937	-0.3	-0.5	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.
