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.

First autumn frost	31 October	24 October	2 November	9 days later	+2.9 days per decade
Growing days	198 days	174 days	209 days	35 days more	+7.3 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

81 years, 1933 to 2025

A day with at least 75.2 mm (3.0 in) of rain is expected about once in 2 years. A day with at least 142.6 mm (5.6 in) of rain is expected about once in 100 years.

Rainfall return levels at Powers: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	75.2 mm (3.0 in)
5 years	96.1 mm (3.8 in)
10 years	108.7 mm (4.3 in)
25 years	123.3 mm (4.9 in)
50 years	133.3 mm (5.2 in)
100 years	142.6 mm (5.6 in)	Longer than the 81 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, 81 years of values from 1933 to 2025.

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: 158.8 mm (6.3 in) in 1996; 127.0 mm (5.0 in) in 1953; 125.7 mm (4.9 in) in 1969.
