The annual mean temperature here has risen by 0.07 C (0.03 to 0.11) per decade over 1893 to 2022. In Fahrenheit: 0.1 F (0.1 to 0.2) 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 | 0.07 C (0.03 to 0.11) per decade | 0.1 F (0.1 to 0.2) per decade | 1893 to 2022 | 98 | Rise |
| Mean daily maximum | 0.08 C (0.02 to 0.13) per decade | 0.14 F (0.04 to 0.24) per decade | 1893 to 2022 | 98 | Rise |
| Mean daily minimum | 0.07 C (0.02 to 0.11) per decade | 0.12 F (0.03 to 0.20) per decade | 1893 to 2022 | 98 | 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
98 years with a frostAcross 98 years with a frost, the median last spring frost at The Dalles falls on 8 April and the median first autumn frost on 25 October, which leaves a median of 199 days between them.
In 1966 to 2022 the median growing season was 210 days. That is 18 days more than in 1893 to 1924.
Fitted over all years, the growing season changes by +2.0 days per decade at this station.
| Measure | Median, all years | Earliest period (1893 to 1924) | Recent period (1966 to 2022) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 8 April | 15 April | 3 April | 12 days earlier | -1.4 days per decade |
| First autumn frost | 25 October | 23 October | 26 October | 3 days later | +0.5 days per decade |
| Growing days | 199 days | 192 days | 210 days | 18 days more | +2.0 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
103 years, 1893 to 2024A day with at least 26.8 mm (1.1 in) of rain is expected about once in 2 years. A day with at least 73.0 mm (2.9 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 26.8 mm (1.1 in) | |
| 5 years | 36.9 mm (1.5 in) | |
| 10 years | 44.4 mm (1.7 in) | |
| 25 years | 55.0 mm (2.2 in) | |
| 50 years | 63.6 mm (2.5 in) | |
| 100 years | 73.0 mm (2.9 in) |
The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 103 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: 106.7 mm (4.2 in) in 1921; 55.9 mm (2.2 in) in 2011; 55.6 mm (2.2 in) in 1956.
Station Changes
2 suspected2 changes were suspected in the annual mean temperature of The Dalles, at 1931 and 1941. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1931 ran 0.6 C (1.0 F) lower than in the years before (likely change).
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1941 ran 0.6 C (1.0 F) higher than in the years before (possible change).
