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

66 years with a frost

Across 66 years with a frost, the median last spring frost at Rosholt falls on 18 May and the median first autumn frost on 25 September, which leaves a median of 130 days between them.

In 1995 to 2025 the median growing season was 144 days. That is 19 days more than in 1949 to 1985.

Fitted over all years, the growing season changes by +3.4 days per decade at this station.

Frost dates and growing season at Rosholt
Measure	Median, all years	Earliest period (1949 to 1985)	Recent period (1995 to 2025)	Recent against earliest	Fitted trend
Last spring frost	18 May	20 May	13 May	7 days earlier	-1.5 days per decade
First autumn frost	25 September	23 September	29 September	6 days later	+1.9 days per decade
Growing days	130 days	125 days	144 days	19 days more	+3.4 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

76 years, 1942 to 2025

A day with at least 50.2 mm (2.0 in) of rain is expected about once in 2 years. A day with at least 104.8 mm (4.1 in) of rain is expected about once in 100 years.

Rainfall return levels at Rosholt: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	50.2 mm (2.0 in)
5 years	63.8 mm (2.5 in)
10 years	73.3 mm (2.9 in)
25 years	85.6 mm (3.4 in)
50 years	95.1 mm (3.7 in)
100 years	104.8 mm (4.1 in)	Longer than the 76 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, 76 years of values from 1942 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: 168.9 mm (6.6 in) in 1995; 83.1 mm (3.3 in) in 1983; 80.0 mm (3.1 in) in 1970.

Climate Twins

2010 to 2025 against 1961 to 1990

Over 2010 to 2025, Rosholt had a mean temperature of 6.9 C (44.5 F) and 950.9 mm (37.4 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Saint Johnsbury (United States, 1,368 km away), Burlington Intl AP (United States, 1,278 km away) and Lawrenceville 3 SW (United States, 1,156 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.
