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
45 years with a frostAcross 45 years with a frost, the median last spring frost at Canyon de Chelly falls on 10 May and the median first autumn frost on 11 October, which leaves a median of 153 days between them.
Fitted over all years, the growing season changes by +5.6 days per decade at this station.
| Measure | Median, all years | Earliest period | Recent period (1988 to 2024) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 10 May | n/a | 5 May | n/a | -2.8 days per decade |
| First autumn frost | 11 October | n/a | 14 October | n/a | +2.7 days per decade |
| Growing days | 153 days | n/a | 164 days | n/a | +5.6 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
51 years, 1971 to 2024A day with at least 24.1 mm (0.9 in) of rain is expected about once in 2 years. A day with at least 49.3 mm (1.9 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 24.1 mm (0.9 in) | |
| 5 years | 31.5 mm (1.2 in) | |
| 10 years | 36.1 mm (1.4 in) | |
| 25 years | 41.7 mm (1.6 in) | |
| 50 years | 45.6 mm (1.8 in) | |
| 100 years | 49.3 mm (1.9 in) | Longer than the 51 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, 51 years of values from 1971 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: 48.8 mm (1.9 in) in 1988; 41.7 mm (1.6 in) in 1994; 39.6 mm (1.6 in) in 2022.
Station Changes
1 suspectedOne change was suspected in the annual mean temperature of Canyon de Chelly, at 2006. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 2006 ran 0.5 C (0.9 F) lower than in the years before (likely change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 2006 | -0.5 | -0.9 | 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, Canyon de Chelly had a mean temperature of 12.2 C (53.9 F) and 226.8 mm (8.9 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Capitol Reef Np (United States, 282 km away), Bluff (United States, 126 km away) and Rocky Ford 2 SE (United States, 559 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Capitol Reef Np | United States | 282 km (175 mi) | 12.2 C (53.9 F) | 189.1 mm (7.4 in) | 0.49 |
| Bluff | United States | 126 km (78 mi) | 11.8 C (53.3 F) | 207.3 mm (8.2 in) | 0.68 |
| Rocky Ford 2 SE | United States | 559 km (347 mi) | 11.7 C (53.0 F) | 277.3 mm (10.9 in) | 0.74 |
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.
