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 Tower 2S falls on 12 June and the median first autumn frost on 20 August, which leaves a median of 69 days between them.
In 1987 to 2025 the median growing season was 72 days. That is 14 days more than in 1896 to 1986.
Fitted over all years, the growing season changes by +1.3 days per decade at this station.
| Measure | Median, all years | Earliest period (1896 to 1986) | Recent period (1987 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 12 June | 16 June | 10 June | 6 days earlier | -0.4 days per decade |
| First autumn frost | 20 August | 15 August | 1 September | 17 days later | +0.9 days per decade |
| Growing days | 69 days | 58 days | 72 days | 14 days more | +1.3 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
90 years, 1896 to 2025A day with at least 51.2 mm (2.0 in) of rain is expected about once in 2 years. A day with at least 147.6 mm (5.8 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 51.2 mm (2.0 in) | |
| 5 years | 70.5 mm (2.8 in) | |
| 10 years | 85.5 mm (3.4 in) | |
| 25 years | 107.5 mm (4.2 in) | |
| 50 years | 126.4 mm (5.0 in) | |
| 100 years | 147.6 mm (5.8 in) | Longer than the 90 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, 90 years of values from 1896 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: 221.0 mm (8.7 in) in 2007; 116.8 mm (4.6 in) in 2024; 101.6 mm (4.0 in) in 1995.
Station Changes
2 suspected2 changes were suspected in the annual mean temperature of Tower 2S, at 1993 and 2006. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1993 ran 0.6 C (1.1 F) lower than in the years before (possible change).
- Relative to 5 neighbouring stations, the station's annual mean temperature from 2006 ran 0.5 C (0.9 F) higher than in the years before (likely change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1993 | -0.6 | -1.1 | possible | 5 |
| 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
2003 to 2025 against 1961 to 1990Over 2003 to 2025, Tower 2S had a mean temperature of 3.1 C (37.6 F) and 718.3 mm (28.3 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Sudbury A (Canada, 876 km away), Arvida (Canada, 1,564 km away) and Duluth (United States, 105 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Sudbury A | Canada | 876 km (544 mi) | 3.4 C (38.0 F) | 864.9 mm (34.1 in) | 0.91 |
| Arvida | Canada | 1,564 km (972 mi) | 3.1 C (37.5 F) | 891.8 mm (35.1 in) | 1.05 |
| Duluth | United States | 105 km (65 mi) | 3.5 C (38.3 F) | 763.4 mm (30.1 in) | 1.07 |
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.
