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

56 years with a frost

Across 56 years with a frost, the median last spring frost at Moose falls on 24 June and the median first autumn frost on 8 August, which leaves a median of 47 days between them.

Fitted over all years, the growing season changes by +6.5 days per decade at this station.

Frost dates and growing season at Moose
Measure	Median, all years	Earliest period	Recent period (1990 to 2023)	Recent against earliest	Fitted trend
Last spring frost	24 June	n/a	23 June	n/a	-0.9 days per decade
First autumn frost	8 August	n/a	27 August	n/a	+5.6 days per decade
Growing days	47 days	n/a	65 days	n/a	+6.5 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

53 years, 1959 to 2021

A day with at least 27.7 mm (1.1 in) of rain is expected about once in 2 years. A day with at least 50.7 mm (2.0 in) of rain is expected about once in 100 years.

Rainfall return levels at Moose: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	27.7 mm (1.1 in)
5 years	34.8 mm (1.4 in)
10 years	39.1 mm (1.5 in)
25 years	44.1 mm (1.7 in)
50 years	47.5 mm (1.9 in)
100 years	50.7 mm (2.0 in)	Longer than the 53 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, 53 years of values from 1959 to 2021.

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: 63.5 mm (2.5 in) in 1978; 40.1 mm (1.6 in) in 2018; 38.9 mm (1.5 in) in 1971.

Station Changes

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

Climate Twins

2009 to 2023 against 1961 to 1990

Over 2009 to 2023, Moose had a mean temperature of 3.6 C (38.6 F) and 576.0 mm (22.7 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Steamboat Springs (United States, 477 km away), Afton (United States, 104 km away) and Border 3 N (United States, 162 km away).

Climate twins of Moose: stations whose 1961 to 1990 climate is closest to its 2009 to 2023 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Steamboat Springs	United States	477 km (296 mi)	3.8 C (38.8 F)	589.4 mm (23.2 in)	0.65
Afton	United States	104 km (65 mi)	3.8 C (38.9 F)	465.6 mm (18.3 in)	0.87
Border 3 N	United States	162 km (101 mi)	3.6 C (38.4 F)	372.3 mm (14.7 in)	1.06

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.
