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.

| Measure | Median, all years | Earliest period | Recent period (1982 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 7 May | n/a | 4 May | n/a | -2.1 days per decade |
| First autumn frost | 1 October | n/a | 5 October | n/a | +1.1 days per decade |
| Growing days | 147 days | n/a | 151 days | n/a | +3.2 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
60 years, 1959 to 2025A day with at least 21.4 mm (0.8 in) of rain is expected about once in 2 years. A day with at least 58.8 mm (2.3 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 21.4 mm (0.8 in) | |
| 5 years | 29.5 mm (1.2 in) | |
| 10 years | 35.6 mm (1.4 in) | |
| 25 years | 44.1 mm (1.7 in) | |
| 50 years | 51.2 mm (2.0 in) | |
| 100 years | 58.8 mm (2.3 in) | Longer than the 60 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, 60 years of values from 1959 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: 51.8 mm (2.0 in) in 1992; 50.8 mm (2.0 in) in 2016; 48.3 mm (1.9 in) in 2001.

Climate Twins
2005 to 2025 against 1961 to 1990Over 2005 to 2025, Dinosaur Nm-Quarry Area had a mean temperature of 9.7 C (49.4 F) and 206.4 mm (8.1 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Boysen Dam (United States, 343 km away), Yinchuan (China, 10,528 km away) and Interior 3 NE (United States, 710 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Boysen Dam | United States | 343 km (213 mi) | 8.7 C (47.6 F) | 233.0 mm (9.2 in) | 1.23 |
| Yinchuan | China | 10,528 km (6,542 mi) | 9.1 C (48.4 F) | 194.1 mm (7.6 in) | 1.28 |
| Interior 3 NE | United States | 710 km (441 mi) | 10.0 C (50.0 F) | 411.0 mm (16.2 in) | 1.45 |
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.
