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

59 years, 1966 to 2025

A day with at least 87.8 mm (3.5 in) of rain is expected about once in 2 years. A day with at least 206.2 mm (8.1 in) of rain is expected about once in 100 years.

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 59 years of values from 1966 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: 229.9 mm (9.1 in) in 1988; 170.2 mm (6.7 in) in 2002; 167.6 mm (6.6 in) in 2003.

Climate Twins

2010 to 2025 against 1961 to 1990

Over 2010 to 2025, Upper Baker Dam had a mean temperature of 8.9 C (48.0 F) and 2,453.3 mm (96.6 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Cedar Lake (United States, 138 km away), Alberni Robertson Creek (Canada, 252 km away) and Cowichan Lake Forestry (Canada, 180 km away).

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.
