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
64 years with a frostAcross 64 years with a frost, the median last spring frost at Tuscaloosa Oliver Dam falls on 23 March and the median first autumn frost on 8 November, which leaves a median of 230 days between them.
In 1938 to 1986 the median growing season was 235 days. That is 9 days more than in 1900 to 1933.
Fitted over all years, the growing season changes by +1.6 days per decade at this station.
| Measure | Median, all years | Earliest period (1900 to 1933) | Recent period (1938 to 1986) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 23 March | 23 March | 22 March | 1 day earlier | -0.6 days per decade |
| First autumn frost | 8 November | 5 November | 10 November | 5 days later | +1.0 days per decade |
| Growing days | 230 days | 226 days | 235 days | 9 days more | +1.6 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
110 years, 1900 to 2025A day with at least 78.8 mm (3.1 in) of rain is expected about once in 2 years. A day with at least 234.3 mm (9.2 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 78.8 mm (3.1 in) | |
| 5 years | 106.8 mm (4.2 in) | |
| 10 years | 129.8 mm (5.1 in) | |
| 25 years | 165.3 mm (6.5 in) | |
| 50 years | 197.1 mm (7.8 in) | |
| 100 years | 234.3 mm (9.2 in) |
The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 110 years of values from 1900 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: 259.3 mm (10.2 in) in 1979; 212.6 mm (8.4 in) in 1916; 181.6 mm (7.1 in) in 1900.
Station Changes
1 suspectedOne change was suspected in the annual mean temperature of Tuscaloosa Oliver Dam, at 1928. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1928 ran 0.3 C (0.5 F) higher than in the years before (likely change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1928 | +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.
