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

85 years with a frost

Across 85 years with a frost, the median last spring frost at Winter falls on 31 May and the median first autumn frost on 15 September, which leaves a median of 107 days between them.

In 1983 to 2020 the median growing season was 121 days. That is 28 days more than in 1915 to 1951.

Fitted over all years, the growing season changes by +4.3 days per decade at this station.

Frost dates and growing season at Winter
Measure	Median, all years	Earliest period (1915 to 1951)	Recent period (1983 to 2020)	Recent against earliest	Fitted trend
Last spring frost	31 May	8 June	22 May	17 days earlier	-2.1 days per decade
First autumn frost	15 September	8 September	20 September	12 days later	+2.3 days per decade
Growing days	107 days	93 days	121 days	28 days more	+4.3 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

87 years, 1917 to 2019

A day with at least 58.2 mm (2.3 in) of rain is expected about once in 2 years. A day with at least 168.8 mm (6.6 in) of rain is expected about once in 100 years.

Rainfall return levels at Winter: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	58.2 mm (2.3 in)
5 years	78.3 mm (3.1 in)
10 years	94.8 mm (3.7 in)
25 years	120.0 mm (4.7 in)
50 years	142.6 mm (5.6 in)
100 years	168.8 mm (6.6 in)	Longer than the 87 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, 87 years of values from 1917 to 2019.

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: 213.4 mm (8.4 in) in 1941; 174.5 mm (6.9 in) in 1958; 119.9 mm (4.7 in) in 2016.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Winter, at 1956 and 1996. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1956 ran 0.5 C (0.8 F) lower than in the years before (possible change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 1996 ran 0.4 C (0.6 F) higher than in the years before (likely change).

Suspected changes in the annual mean temperature at Winter, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1956	-0.5	-0.8	possible	5
1996	+0.4	+0.6	likely	5

Possible change at the station (a move, a new instrument or a new site); the record is kept as measured. A "likely" change has a larger test statistic than a "possible" one. Neither says why the station differs from its neighbours. How changes are found, and the largest ones.

Climate Twins

2005 to 2020 against 1961 to 1990

Over 2005 to 2020, Winter had a mean temperature of 5.1 C (41.2 F) and 908.5 mm (35.8 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Merrill (United States, 125 km away), Antigo (United States, 163 km away) and Chalk River Aecl (Canada, 1,053 km away).

Climate twins of Winter: stations whose 1961 to 1990 climate is closest to its 2005 to 2020 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Merrill	United States	125 km (78 mi)	5.1 C (41.2 F)	813.9 mm (32.0 in)	0.75
Antigo	United States	163 km (101 mi)	5.1 C (41.2 F)	817.3 mm (32.2 in)	0.75
Chalk River Aecl	Canada	1,053 km (654 mi)	4.8 C (40.6 F)	822.1 mm (32.4 in)	0.77

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.
