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
62 years with a frostAcross 62 years with a frost, the median last spring frost at Bely Island falls on 29 June and the median first autumn frost on 2 July, which leaves a median of 4 days between them.
In 1977 to 2017 the median growing season was 5 days. That is 1 day more than in 1934 to 1972.
Fitted over all years, the growing season changes by +4.2 days per decade at this station.
| Measure | Median, all years | Earliest period (1934 to 1972) | Recent period (1977 to 2017) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 29 June | 30 June | 29 June | 1 day earlier | -0.1 days per decade |
| First autumn frost | 2 July | 2 July | 2 July | no change | +4.0 days per decade |
| Growing days | 4 days | 4 days | 5 days | 1 day more | +4.2 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
50 years, 1934 to 2024A day with at least 14.2 mm (0.6 in) of rain is expected about once in 2 years. A day with at least 33.5 mm (1.3 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 14.2 mm (0.6 in) | |
| 5 years | 20.3 mm (0.8 in) | |
| 10 years | 23.9 mm (0.9 in) | |
| 25 years | 28.1 mm (1.1 in) | |
| 50 years | 30.9 mm (1.2 in) | |
| 100 years | 33.5 mm (1.3 in) | Longer than the 50 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, 50 years of values from 1934 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: 29.3 mm (1.2 in) in 1982; 27.9 mm (1.1 in) in 1974; 27.8 mm (1.1 in) in 1998.
Climate Twins
1996 to 2017 against 1961 to 1990Over 1996 to 2017, Bely Island had a mean temperature of -8.5 C (16.6 F) and 246.9 mm (9.7 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Marre-Sale (Russia, 417 km away), Amderma (Russia, 494 km away) and Tin City (United States, 4,001 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Marre-Sale | Russia | 417 km (259 mi) | -8.4 C (16.9 F) | 298.2 mm (11.7 in) | 1.01 |
| Amderma | Russia | 494 km (307 mi) | -7.0 C (19.4 F) | 408.7 mm (16.1 in) | 1.86 |
| Tin City | United States | 4,001 km (2,486 mi) | -6.2 C (20.8 F) | 345.5 mm (13.6 in) | 2.69 |
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.
