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

68 years with a frost

Across 68 years with a frost, the median last spring frost at Wallace falls on 18 May and the median first autumn frost on 21 September, which leaves a median of 127 days between them.

In 1985 to 2023 the median growing season was 139 days. That is 21 days more than in 1942 to 1976.

Fitted over all years, the growing season changes by +6.2 days per decade at this station.

Frost dates and growing season at Wallace
Measure	Median, all years	Earliest period (1942 to 1976)	Recent period (1985 to 2023)	Recent against earliest	Fitted trend
Last spring frost	18 May	23 May	13 May	10 days earlier	-2.6 days per decade
First autumn frost	21 September	14 September	3 October	19 days later	+3.5 days per decade
Growing days	127 days	118 days	139 days	21 days more	+6.2 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

68 years, 1942 to 2024

A day with at least 41.1 mm (1.6 in) of rain is expected about once in 2 years. A day with at least 77.4 mm (3.0 in) of rain is expected about once in 100 years.

Rainfall return levels at Wallace: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	41.1 mm (1.6 in)
5 years	51.9 mm (2.0 in)
10 years	58.7 mm (2.3 in)
25 years	66.6 mm (2.6 in)
50 years	72.2 mm (2.8 in)
100 years	77.4 mm (3.0 in)	Longer than the 68 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, 68 years of values from 1942 to 2024.

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: 78.2 mm (3.1 in) in 1975; 78.0 mm (3.1 in) in 1946; 78.0 mm (3.1 in) in 1974.

Climate Twins

2000 to 2023 against 1961 to 1990

Over 2000 to 2023, Wallace had a mean temperature of 7.8 C (46.0 F) and 922.0 mm (36.3 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Sandpoint Exp STN (United States, 103 km away), Kaslo (Canada, 281 km away) and New Denver (Canada, 300 km away).

Climate twins of Wallace: stations whose 1961 to 1990 climate is closest to its 2000 to 2023 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Sandpoint Exp STN	United States	103 km (64 mi)	7.5 C (45.5 F)	840.8 mm (33.1 in)	0.88
Kaslo	Canada	281 km (175 mi)	7.2 C (45.0 F)	856.7 mm (33.7 in)	1.04
New Denver	Canada	300 km (186 mi)	7.5 C (45.5 F)	862.2 mm (33.9 in)	1.05

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.
