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

103 years with a frost

Across 103 years with a frost, the median last spring frost at Willow City falls on 26 May and the median first autumn frost on 13 September, which leaves a median of 112 days between them.

In 1991 to 2024 the median growing season was 127 days. That is 33 days more than in 1898 to 1939.

Fitted over all years, the growing season changes by +4.1 days per decade at this station.

First autumn frost13 September7 September22 September15 days later+2.3 days per decade
Growing days112 days94 days127 days33 days more+4.1 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

98 years, 1902 to 2023

A day with at least 40.8 mm (1.6 in) of rain is expected about once in 2 years. A day with at least 135.8 mm (5.3 in) of rain is expected about once in 100 years.

50 years115.3 mm (4.5 in)
100 years135.8 mm (5.3 in)Longer than the 98 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, 98 years of values from 1902 to 2023.

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: 175.3 mm (6.9 in) in 1982; 117.9 mm (4.6 in) in 1947; 93.5 mm (3.7 in) in 1974.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Willow City, at 1995 and 2012. Each is measured against neighbouring stations.

  • Relative to 5 neighbouring stations, the station's annual mean temperature from 1995 ran 0.3 C (0.6 F) higher than in the years before (likely change).
  • Relative to 5 neighbouring stations, the station's annual mean temperature from 2012 ran 0.6 C (1.1 F) lower than in the years before (possible change).

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

2008 to 2024 against 1961 to 1990

Over 2008 to 2024, Willow City had a mean temperature of 3.3 C (37.9 F) and 434.6 mm (17.1 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Petersburg 2 N (United States, 180 km away), Cavalier 7NW (United States, 192 km away) and Bowbells (United States, 145 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.
