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
60 years with a frostAcross 60 years with a frost, the median last spring frost at Clearmont 5 SW falls on 25 May and the median first autumn frost on 14 September, which leaves a median of 113 days between them.
In 1990 to 2024 the median growing season was 118 days. That is 13 days more than in 1958 to 1989.
Fitted over all years, the growing season changes by +3.3 days per decade at this station.
| Measure | Median, all years | Earliest period (1958 to 1989) | Recent period (1990 to 2024) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 25 May | 26 May | 24 May | 2 days earlier | -1.0 days per decade |
| First autumn frost | 14 September | 10 September | 18 September | 8 days later | +2.3 days per decade |
| Growing days | 113 days | 105 days | 118 days | 13 days more | +3.3 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
74 years, 1950 to 2024A day with at least 32.1 mm (1.3 in) of rain is expected about once in 2 years. A day with at least 78.8 mm (3.1 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 32.1 mm (1.3 in) | |
| 5 years | 43.6 mm (1.7 in) | |
| 10 years | 51.7 mm (2.0 in) | |
| 25 years | 62.3 mm (2.5 in) | |
| 50 years | 70.4 mm (2.8 in) | |
| 100 years | 78.8 mm (3.1 in) | Longer than the 74 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, 74 years of values from 1950 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: 91.9 mm (3.6 in) in 1985; 69.1 mm (2.7 in) in 1962; 64.5 mm (2.5 in) in 1980.

Climate Twins
2010 to 2024 against 1961 to 1990Over 2010 to 2024, Clearmont 5 SW had a mean temperature of 6.9 C (44.4 F) and 288.1 mm (11.3 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Moorcroft 3S (United States, 127 km away), Bates Creek #2 (United States, 217 km away) and Lander AP (United States, 268 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Moorcroft 3S | United States | 127 km (79 mi) | 6.8 C (44.3 F) | 311.8 mm (12.3 in) | 0.94 |
| Bates Creek #2 | United States | 217 km (135 mi) | 7.2 C (44.9 F) | 315.9 mm (12.4 in) | 0.95 |
| Lander AP | United States | 268 km (167 mi) | 7.0 C (44.5 F) | 332.9 mm (13.1 in) | 1.00 |
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.
