The fitted trend in annual mean temperature here over 1917 to 2022 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 0.10) per decade. The slope is a straight line fitted to 98 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 0.10) per decade | 1917 to 2022 | 98 | Not clearly different from zero |
| Mean daily maximum | 0.02 C (-0.04 to 0.07) per decade | 0.03 F (-0.07 to 0.13) per decade | 1917 to 2022 | 98 | Not clearly different from zero |
| Mean daily minimum | 0.00 C (-0.04 to 0.05) per decade | 0.00 F (-0.08 to 0.08) per decade | 1917 to 2022 | 98 | Not clearly different from zero |
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
98 years with a frostAcross 98 years with a frost, the median last spring frost at Moro falls on 10 May and the median first autumn frost on 6 October, which leaves a median of 148 days between them.
In 1989 to 2022 the median growing season was 150 days. That is 4 days fewer than in 1917 to 1947.
Fitted over all years, the growing season changes by +0.7 days per decade at this station.
| Measure | Median, all years | Earliest period (1917 to 1947) | Recent period (1989 to 2022) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 10 May | 7 May | 8 May | 1 day later | -0.2 days per decade |
| First autumn frost | 6 October | 8 October | 6 October | 2 days earlier | +0.4 days per decade |
| Growing days | 148 days | 154 days | 150 days | 4 days fewer | +0.7 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
104 years, 1917 to 2022A day with at least 20.3 mm (0.8 in) of rain is expected about once in 2 years. A day with at least 49.7 mm (2.0 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 20.3 mm (0.8 in) | |
| 5 years | 27.4 mm (1.1 in) | |
| 10 years | 32.5 mm (1.3 in) | |
| 25 years | 39.1 mm (1.5 in) | |
| 50 years | 44.4 mm (1.7 in) | |
| 100 years | 49.7 mm (2.0 in) |
The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 104 years of values from 1917 to 2022.
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: 57.2 mm (2.3 in) in 1921; 42.4 mm (1.7 in) in 1953; 41.7 mm (1.6 in) in 1972.
Station Changes
1 suspectedOne change was suspected in the annual mean temperature of Moro, at 1958. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1958 ran 0.2 C (0.3 F) lower than in the years before (possible change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1958 | -0.2 | -0.3 | 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
2005 to 2022 against 1961 to 1990Over 2005 to 2022, Moro had a mean temperature of 9.7 C (49.5 F) and 284.2 mm (11.2 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Adel (United States, 374 km away), Mitchell 2 NW (United States, 109 km away) and Carson City (United States, 711 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Adel | United States | 374 km (232 mi) | 9.7 C (49.4 F) | 249.5 mm (9.8 in) | 0.56 |
| Mitchell 2 NW | United States | 109 km (68 mi) | 9.6 C (49.2 F) | 294.1 mm (11.6 in) | 0.59 |
| Carson City | United States | 711 km (442 mi) | 10.1 C (50.2 F) | 246.8 mm (9.7 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.
