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 at Bloomer
Measure	Median, all years	Earliest period (1948 to 1979)	Recent period (1994 to 2025)	Recent against earliest	Fitted trend
Last spring frost	11 May	12 May	8 May	4 days earlier	-0.6 days per decade
First autumn frost	28 September	25 September	3 October	8 days later	+1.7 days per decade
Growing days	143 days	135 days	147 days	12 days more	+2.3 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.

50 years	132.0 mm (5.2 in)
100 years	156.7 mm (6.2 in)	Longer than the 78 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, 78 years of values from 1945 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: 170.2 mm (6.7 in) in 1959; 128.3 mm (5.1 in) in 1990; 116.6 mm (4.6 in) in 1977.

Climate Twins

2011 to 2025 against 1961 to 1990

Over 2011 to 2025, Bloomer had a mean temperature of 6.6 C (43.8 F) and 846.1 mm (33.3 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Wisconsin Rapids (United States, 154 km away), Grand Meadow (United States, 176 km away) and Laprairie (Canada, 1,411 km away).

Climate twins of Bloomer: stations whose 1961 to 1990 climate is closest to its 2011 to 2025 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Wisconsin Rapids	United States	154 km (96 mi)	6.4 C (43.5 F)	828.2 mm (32.6 in)	0.88
Grand Meadow	United States	176 km (109 mi)	6.4 C (43.4 F)	823.9 mm (32.4 in)	0.89
Laprairie	Canada	1,411 km (877 mi)	6.5 C (43.6 F)	775.0 mm (30.5 in)	0.90

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.
