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 Cushman Powerhouse #2 falls on 6 April and the median first autumn frost on 10 November, which leaves a median of 217 days between them.

Fitted over all years, the growing season changes by +7.4 days per decade at this station.

Frost dates and growing season at Cushman Powerhouse #2
Measure	Median, all years	Earliest period	Recent period (1993 to 2025)	Recent against earliest	Fitted trend
Last spring frost	6 April	n/a	2 April	n/a	-6.3 days per decade
First autumn frost	10 November	n/a	11 November	n/a	+1.0 days per decade
Growing days	217 days	n/a	222 days	n/a	+7.4 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

52 years, 1974 to 2025

A day with at least 104.6 mm (4.1 in) of rain is expected about once in 2 years. A day with at least 213.2 mm (8.4 in) of rain is expected about once in 100 years.

Rainfall return levels at Cushman Powerhouse #2: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	104.6 mm (4.1 in)
5 years	132.9 mm (5.2 in)
10 years	151.9 mm (6.0 in)
25 years	176.3 mm (6.9 in)
50 years	194.7 mm (7.7 in)
100 years	213.2 mm (8.4 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 1974 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: 210.8 mm (8.3 in) in 2003; 183.6 mm (7.2 in) in 1997; 177.8 mm (7.0 in) in 2007.

No change in the annual mean temperature of this station was found against its neighbours.

Climate Twins

2011 to 2025 against 1961 to 1990

Over 2011 to 2025, Cushman Powerhouse #2 had a mean temperature of 10.7 C (51.3 F) and 2,340.8 mm (92.2 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Detroit Dam (United States, 302 km away), Pitt Polder (Canada, 216 km away) and Skamania Fish Hatchery (United States, 207 km away).

Climate twins of Cushman Powerhouse #2: stations whose 1961 to 1990 climate is closest to its 2011 to 2025 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Detroit Dam	United States	302 km (188 mi)	10.6 C (51.0 F)	2,216.0 mm (87.2 in)	0.85
Pitt Polder	Canada	216 km (134 mi)	9.5 C (49.1 F)	2,375.6 mm (93.5 in)	1.36
Skamania Fish Hatchery	United States	207 km (129 mi)	9.7 C (49.4 F)	2,191.5 mm (86.3 in)	1.36

Twins are stations, not cities. A twin is one of the three stations at least 100 km away whose earlier climate is closest to this station's recent one, so a close match does not mean the two places look alike in other ways. A station move or a gap in a record can change that station's averages. The list describes past climate; it is not a forecast and does not say what caused any change. How twins are found, and a search for any station.
