The fitted trend in annual mean temperature here over 1915 to 2017 is 0.01 C (-0.04 to 0.06) per decade. The interval includes zero, so the trend is not clearly different from zero. In Fahrenheit: 0.02 F (-0.07 to 0.11) per decade. The slope is a straight line fitted to 84 complete years; the brackets give its 95 percent interval.
| Measure | Per decade (C) | Per decade (F) | Period | Complete years | Reading |
|---|---|---|---|---|---|
| Annual mean temperature | 0.01 C (-0.04 to 0.06) per decade | 0.02 F (-0.07 to 0.11) per decade | 1915 to 2017 | 84 | Not clearly different from zero |
| Mean daily maximum | -0.2 C (-0.2 to -0.1) per decade | -0.3 F (-0.4 to -0.2) per decade | 1915 to 2017 | 84 | Fall |
| Mean daily minimum | 0.2 C (0.1 to 0.2) per decade | 0.3 F (0.2 to 0.4) per decade | 1915 to 2017 | 84 | Rise |
A year is complete when all 12 months have at least 20 days of both daily maximum and daily minimum readings. The annual mean is the mean of the monthly means. The trend describes this one station over this period; it does not say what caused the change.

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
84 years with a frostAcross 84 years with a frost, the median last spring frost at Moorhead falls on 17 March and the median first autumn frost on 9 November, which leaves a median of 235 days between them.
In 1984 to 2017 the median growing season was 259 days. That is 30 days more than in 1915 to 1959.
Fitted over all years, the growing season changes by +4.5 days per decade at this station.
| Measure | Median, all years | Earliest period (1915 to 1959) | Recent period (1984 to 2017) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 17 March | 19 March | 9 March | 10 days earlier | -1.7 days per decade |
| First autumn frost | 9 November | 3 November | 21 November | 18 days later | +2.8 days per decade |
| Growing days | 235 days | 229 days | 259 days | 30 days more | +4.5 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
94 years, 1914 to 2017A day with at least 87.4 mm (3.4 in) of rain is expected about once in 2 years. A day with at least 225.4 mm (8.9 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 87.4 mm (3.4 in) | |
| 5 years | 117.0 mm (4.6 in) | |
| 10 years | 139.2 mm (5.5 in) | |
| 25 years | 170.8 mm (6.7 in) | |
| 50 years | 196.9 mm (7.8 in) | |
| 100 years | 225.4 mm (8.9 in) | Longer than the 94 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, 94 years of values from 1914 to 2017.
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: 200.9 mm (7.9 in) in 2000; 190.8 mm (7.5 in) in 1958; 186.4 mm (7.3 in) in 1982.
Station Changes
2 suspected2 changes were suspected in the annual mean temperature of Moorhead, at 1935 and 1967. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1935 ran 0.4 C (0.6 F) higher than in the years before (likely change).
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1967 ran 0.2 C (0.4 F) higher than in the years before (possible change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1935 | +0.4 | +0.6 | likely | 5 |
| 1967 | +0.2 | +0.4 | possible | 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
2003 to 2017 against 1961 to 1990Over 2003 to 2017, Moorhead had a mean temperature of 17.9 C (64.3 F) and 1,293.7 mm (50.9 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Minden (United States, 276 km away), Red Rvr Rsch STN (United States, 314 km away) and Center (United States, 395 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Minden | United States | 276 km (171 mi) | 17.8 C (64.0 F) | 1,268.4 mm (49.9 in) | 0.41 |
| Red Rvr Rsch STN | United States | 314 km (195 mi) | 17.9 C (64.2 F) | 1,223.2 mm (48.2 in) | 0.55 |
| Center | United States | 395 km (245 mi) | 18.0 C (64.3 F) | 1,266.0 mm (49.8 in) | 0.55 |
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.
