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

80 years with a frost

Across 80 years with a frost, the median last spring frost at Electra P H falls on 26 March and the median first autumn frost on 18 November, which leaves a median of 237 days between them.

In 1960 to 1993 the median growing season was 221 days. That is 25 days fewer than in 1908 to 1939.

Fitted over all years, the growing season changes by -4.5 days per decade at this station.

Frost dates and growing season at Electra P H
Measure	Median, all years	Earliest period (1908 to 1939)	Recent period (1960 to 1993)	Recent against earliest	Fitted trend
Last spring frost	26 March	23 March	10 April	18 days later	+3.9 days per decade
First autumn frost	18 November	19 November	19 November	no change	-0.5 days per decade
Growing days	237 days	246 days	221 days	25 days fewer	-4.5 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

70 years, 1908 to 1993

A day with at least 57.1 mm (2.2 in) of rain is expected about once in 2 years. A day with at least 130.8 mm (5.1 in) of rain is expected about once in 100 years.

Rainfall return levels at Electra P H: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	57.1 mm (2.2 in)
5 years	73.7 mm (2.9 in)
10 years	85.8 mm (3.4 in)
25 years	102.6 mm (4.0 in)
50 years	116.2 mm (4.6 in)
100 years	130.8 mm (5.1 in)	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 1908 to 1993.

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: 132.6 mm (5.2 in) in 1942; 122.7 mm (4.8 in) in 1955; 100.6 mm (4.0 in) in 1950.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Electra P H, at 1944. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1944 ran 0.4 C (0.7 F) higher than in the years before (likely change).

Year	Shift (C)	Shift (F)	Strength	Neighbours
1944	+0.4	+0.7	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.
