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

71 years with a frost

Across 71 years with a frost, the median last spring frost at Upham 3 N falls on 19 May and the median first autumn frost on 13 September, which leaves a median of 117 days between them.

In 1992 to 2021 the median growing season was 130 days. That is 23 days more than in 1949 to 1980.

Fitted over all years, the growing season changes by +6.3 days per decade at this station.

Frost dates and growing season at Upham 3 N
Measure	Median, all years	Earliest period (1949 to 1980)	Recent period (1992 to 2021)	Recent against earliest	Fitted trend
Last spring frost	19 May	27 May	16 May	11 days earlier	-2.3 days per decade
First autumn frost	13 September	10 September	22 September	12 days later	+4.1 days per decade
Growing days	117 days	107 days	130 days	23 days more	+6.3 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.

Rainfall Return Levels

81 years, 1941 to 2021

A day with at least 44.8 mm (1.8 in) of rain is expected about once in 2 years. A day with at least 114.9 mm (4.5 in) of rain is expected about once in 100 years.

Rainfall return levels at Upham 3 N: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	44.8 mm (1.8 in)
5 years	62.6 mm (2.5 in)
10 years	74.8 mm (2.9 in)
25 years	90.6 mm (3.6 in)
50 years	102.6 mm (4.0 in)
100 years	114.9 mm (4.5 in)	Longer than the 81 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, 81 years of values from 1941 to 2021.

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: 135.6 mm (5.3 in) in 1968; 98.3 mm (3.9 in) in 1953; 96.8 mm (3.8 in) in 2005.

Station Changes

3 suspected

3 changes were suspected in the annual mean temperature of Upham 3 N, at 1968, 1980 and 2006. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1980 ran 0.3 C (0.5 F) higher than in the years before (likely change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 2006 ran 0.4 C (0.6 F) higher than in the years before (likely change).

Suspected changes in the annual mean temperature at Upham 3 N, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1968	-0.6	-1.2	likely	5
1980	+0.3	+0.5	likely	5
2006	+0.4	+0.6	likely	5

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

2007 to 2021 against 1961 to 1990

Over 2007 to 2021, Upham 3 N had a mean temperature of 4.1 C (39.4 F) and 474.1 mm (18.7 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Devils Lake Kdlr (United States, 148 km away), Colgate (United States, 275 km away) and Carrington (United States, 176 km away).

Climate twins of Upham 3 N: stations whose 1961 to 1990 climate is closest to its 2007 to 2021 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Devils Lake Kdlr	United States	148 km (92 mi)	4.2 C (39.5 F)	445.6 mm (17.5 in)	0.90
Colgate	United States	275 km (171 mi)	4.4 C (40.0 F)	450.7 mm (17.7 in)	0.92
Carrington	United States	176 km (109 mi)	4.1 C (39.4 F)	458.2 mm (18.0 in)	0.96

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.
