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
57 years with a frostAcross 57 years with a frost, the median last spring frost at Jasper falls on 10 March and the median first autumn frost on 14 November, which leaves a median of 248 days between them.
Fitted over all years, the growing season changes by +4.4 days per decade at this station.
| Measure | Median, all years | Earliest period | Recent period (1985 to 2019) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 10 March | n/a | 8 March | n/a | -1.4 days per decade |
| First autumn frost | 14 November | n/a | 21 November | n/a | +3.0 days per decade |
| Growing days | 248 days | n/a | 260 days | n/a | +4.4 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
69 years, 1951 to 2019A day with at least 90.7 mm (3.6 in) of rain is expected about once in 2 years. A day with at least 251.8 mm (9.9 in) of rain is expected about once in 100 years.

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 69 years of values from 1951 to 2019.
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: 268.5 mm (10.6 in) in 2012; 259.1 mm (10.2 in) in 1962; 214.6 mm (8.4 in) in 1973.
Station Changes
2 suspected2 changes were suspected in the annual mean temperature of Jasper, at 1968 and 1987. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1968 ran 0.2 C (0.4 F) lower than in the years before (possible change).
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1987 ran 0.3 C (0.5 F) lower than in the years before (likely change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1968 | -0.2 | -0.4 | possible | 5 |
| 1987 | -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.
Climate Twins
2005 to 2019 against 1961 to 1990Over 2005 to 2019, Jasper had a mean temperature of 19.5 C (67.1 F) and 1,330.8 mm (52.4 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Sapelo Is (United States, 188 km away), Quincy 3 SSW (United States, 158 km away) and Nahunta 6NE (United States, 130 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Sapelo Is | United States | 188 km (117 mi) | 19.4 C (66.9 F) | 1,305.8 mm (51.4 in) | 0.67 |
| Quincy 3 SSW | United States | 158 km (98 mi) | 19.3 C (66.8 F) | 1,419.5 mm (55.9 in) | 0.70 |
| Nahunta 6NE | United States | 130 km (81 mi) | 19.3 C (66.7 F) | 1,246.7 mm (49.1 in) | 0.70 |
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.
