The fitted trend in annual mean temperature here over 1894 to 2024 is -0.05 C (-0.09 to 0.00) per decade. The interval includes zero, so the trend is not clearly different from zero. In Fahrenheit: -0.1 F (-0.2 to 0.0) per decade. The slope is a straight line fitted to 108 complete years; the brackets give its 95 percent interval.
| Measure | Per decade (C) | Per decade (F) | Period | Complete years | Reading |
|---|---|---|---|---|---|
| Annual mean temperature | -0.05 C (-0.09 to 0.00) per decade | -0.1 F (-0.2 to 0.0) per decade | 1894 to 2024 | 108 | Not clearly different from zero |
| Mean daily maximum | -0.01 C (-0.07 to 0.04) per decade | -0.03 F (-0.12 to 0.07) per decade | 1894 to 2024 | 108 | Not clearly different from zero |
| Mean daily minimum | -0.08 C (-0.12 to -0.03) per decade | -0.1 F (-0.2 to -0.1) per decade | 1894 to 2024 | 108 | Fall |
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
108 years with a frostAcross 108 years with a frost, the median last spring frost at Algona falls on 2 May and the median first autumn frost on 5 October, which leaves a median of 158 days between them.
In 1985 to 2024 the median growing season was 162 days. That is 5 days more than in 1894 to 1926.
Fitted over all years, the growing season changes by -0.1 days per decade at this station.
| Measure | Median, all years | Earliest period (1894 to 1926) | Recent period (1985 to 2024) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 2 May | 2 May | 28 April | 4 days earlier | -0.1 days per decade |
| First autumn frost | 5 October | 6 October | 4 October | 2 days earlier | -0.2 days per decade |
| Growing days | 158 days | 157 days | 162 days | 5 days more | -0.1 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
125 years, 1893 to 2024A day with at least 60.7 mm (2.4 in) of rain is expected about once in 2 years. A day with at least 165.8 mm (6.5 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 60.7 mm (2.4 in) | |
| 5 years | 82.8 mm (3.3 in) | |
| 10 years | 99.6 mm (3.9 in) | |
| 25 years | 123.7 mm (4.9 in) | |
| 50 years | 143.7 mm (5.7 in) | |
| 100 years | 165.8 mm (6.5 in) |
The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 125 years of values from 1893 to 2024.
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: 175.3 mm (6.9 in) in 2006; 157.0 mm (6.2 in) in 1954; 137.9 mm (5.4 in) in 1941.
Station Changes
2 suspected2 changes were suspected in the annual mean temperature of Algona, at 1925 and 1950. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1925 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 1950 ran 0.3 C (0.5 F) lower than in the years before (likely change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1925 | +0.3 | +0.5 | likely | 5 |
| 1950 | -0.3 | -0.5 | 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
2008 to 2024 against 1961 to 1990Over 2008 to 2024, Algona had a mean temperature of 7.8 C (46.1 F) and 822.3 mm (32.4 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Waterloo Muni AP (United States, 159 km away), Decorah (United States, 199 km away) and Alma Dam 4 (United States, 232 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Waterloo Muni AP | United States | 159 km (99 mi) | 7.9 C (46.2 F) | 856.2 mm (33.7 in) | 0.71 |
| Decorah | United States | 199 km (124 mi) | 7.8 C (46.0 F) | 810.1 mm (31.9 in) | 0.71 |
| Alma Dam 4 | United States | 232 km (144 mi) | 8.0 C (46.3 F) | 820.2 mm (32.3 in) | 0.72 |
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.
