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.

A day with at least 56.6 mm (2.2 in) of rain is expected about once in 2 years. A day with at least 149.5 mm (5.9 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, 88 years of values from 1894 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: 226.1 mm (8.9 in) in 1972; 114.8 mm (4.5 in) in 1955; 109.2 mm (4.3 in) in 1941.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Long Prairie, at 1962. Each is measured against neighbouring stations.

  • Relative to 5 neighbouring stations, the station's annual mean temperature from 1962 ran 0.4 C (0.8 F) higher than in the years before (likely 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

2011 to 2025 against 1961 to 1990

Over 2011 to 2025, Long Prairie had a mean temperature of 5.0 C (41.0 F) and 791.2 mm (31.1 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Arnprior Grandon (Canada, 1,437 km away), Chalk River Aecl (Canada, 1,351 km away) and Rhinelander (United States, 424 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.
