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
61 years with a frostAcross 61 years with a frost, the median last spring frost at Ojmjakon falls on 22 June and the median first autumn frost on 10 July, which leaves a median of 21 days between them.
In 1989 to 2023 the median growing season was 43 days. That is 29 days more than in 1953 to 1987.
Fitted over all years, the growing season changes by +5.2 days per decade at this station.
| Measure | Median, all years | Earliest period (1953 to 1987) | Recent period (1989 to 2023) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 22 June | 25 June | 17 June | 8 days earlier | -2.0 days per decade |
| First autumn frost | 10 July | 8 July | 21 July | 13 days later | +3.2 days per decade |
| Growing days | 21 days | 14 days | 43 days | 29 days more | +5.2 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
78 years, 1943 to 2023A day with at least 17.9 mm (0.7 in) of rain is expected about once in 2 years. A day with at least 37.7 mm (1.5 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 17.9 mm (0.7 in) | |
| 5 years | 23.6 mm (0.9 in) | |
| 10 years | 27.2 mm (1.1 in) | |
| 25 years | 31.6 mm (1.2 in) | |
| 50 years | 34.7 mm (1.4 in) | |
| 100 years | 37.7 mm (1.5 in) | Longer than the 78 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, 78 years of values from 1943 to 2023.
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: 39.4 mm (1.6 in) in 1979; 35.4 mm (1.4 in) in 2001; 32.1 mm (1.3 in) in 2012.
Climate Twins
2006 to 2023 against 1961 to 1990Over 2006 to 2023, Ojmjakon had a mean temperature of -14.3 C (6.2 F) and 241.6 mm (9.5 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Verhojansk (Russia, 657 km away), Ust-Moma (Russia, 356 km away) and Tompo (Russia, 368 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Verhojansk | Russia | 657 km (408 mi) | -15.1 C (4.7 F) | 171.6 mm (6.8 in) | 1.31 |
| Ust-Moma | Russia | 356 km (221 mi) | -14.2 C (6.4 F) | 200.4 mm (7.9 in) | 1.37 |
| Tompo | Russia | 368 km (229 mi) | -13.3 C (8.1 F) | 286.6 mm (11.3 in) | 1.61 |
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.
