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

87 years with a frost

Across 87 years with a frost, the median last spring frost at Forman 5 SSE falls on 13 May and the median first autumn frost on 23 September, which leaves a median of 136 days between them.

In 1982 to 2020 the median growing season was 146 days. That is 20 days more than in 1893 to 1950.

Fitted over all years, the growing season changes by +3.2 days per decade at this station.

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

104 years, 1893 to 2020

A day with at least 47.2 mm (1.9 in) of rain is expected about once in 2 years. A day with at least 117.9 mm (4.6 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, 104 years of values from 1893 to 2020.

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: 116.6 mm (4.6 in) in 1939; 105.4 mm (4.1 in) in 1949; 99.1 mm (3.9 in) in 1914.

Climate Twins

1997 to 2020 against 1961 to 1990

Over 1997 to 2020, Forman 5 SSE had a mean temperature of 5.8 C (42.4 F) and 613.6 mm (24.2 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Glenwood 2WNW (United States, 172 km away), Watertown Rgnl AP (United States, 130 km away) and Pipestone (United States, 246 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.
