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.

| First autumn frost | 29 October | 25 October | 1 November | 7 days later | +1.5 days per decade |
| Growing days | 192 days | 186 days | 197 days | 11 days more | +1.8 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
48 years, 1948 to 2025A day with at least 46.9 mm (1.8 in) of rain is expected about once in 2 years. A day with at least 117.0 mm (4.6 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 46.9 mm (1.8 in) | |
| 5 years | 63.7 mm (2.5 in) | |
| 10 years | 75.5 mm (3.0 in) | |
| 25 years | 91.4 mm (3.6 in) | |
| 50 years | 103.9 mm (4.1 in) | Longer than the 48 years of record |
| 100 years | 117.0 mm (4.6 in) | Longer than the 48 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, 48 years of values from 1948 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: 103.4 mm (4.1 in) in 2016; 92.7 mm (3.6 in) in 1956; 89.7 mm (3.5 in) in 1968.
Station Changes
2 suspected2 changes were suspected in the annual mean temperature of Detroit City AP, at 2010 and 2020. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 2010 ran 0.4 C (0.7 F) lower than in the years before (likely change).
- Relative to 5 neighbouring stations, the station's annual mean temperature from 2020 ran 0.8 C (1.5 F) higher than in the years before (likely change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 2010 | -0.4 | -0.7 | likely | 5 |
| 2020 | +0.8 | +1.5 | 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, Detroit City AP had a mean temperature of 11.1 C (51.9 F) and 784.4 mm (30.9 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Farrell Sharon (United States, 245 km away), Pittsburgh WSO City (United States, 332 km away) and Dayton Intl AP (United States, 296 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Farrell Sharon | United States | 245 km (152 mi) | 10.8 C (51.4 F) | 893.6 mm (35.2 in) | 0.83 |
| Pittsburgh WSO City | United States | 332 km (206 mi) | 11.4 C (52.5 F) | 882.0 mm (34.7 in) | 0.87 |
| Dayton Intl AP | United States | 296 km (184 mi) | 11.0 C (51.7 F) | 931.4 mm (36.7 in) | 0.89 |
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.
