Weather Records Against Chance: Finland

In the 2020s, record highs ran at 2.27 times the number expected by chance in Finland and record lows at 0.37 times.

Key Facts

  • In the 2020s so far (to 2026-10-17), 18,472 record highs of daily temperature were observed in Finland against 8,140 expected by chance, 2.27 times the expected number.
  • In the 2020s so far (to 2026-10-17), 3,023 record lows of daily temperature were observed in Finland against 8,140 expected by chance, 0.37 times the expected number.
  • By type in the 2020s in Finland, observed over expected was 2.28 for record highs of the daily maximum, 0.39 for record lows of the daily maximum, 2.26 for record highs of the daily minimum, 0.35 for record lows of the daily minimum.
  • In 2026 (to 2026-10-17), record highs ran at 1.39 times the expected number in Finland and record lows at 0.35 times.
  • Expected counts assume a stable climate: the k-th year of a station's record sets a record on a given day with chance 1 in k.
  • Readings are whole tenths of a degree and ties are not records, so strict records run below the naive expectation even without a trend. This page compares with the the reference period level and not with 1.

How to Read This Page

In a stable climate, the k-th year of a station's record sets a record on a given day with chance 1 in k. Adding that chance up over every station, day and year gives the number of daily records expected without any change. The site records a station's records from its 31st year of data, so a station-year counts from there.

Readings are whole tenths of a degree, and a tie is not a record, so strict records run below the naive expectation even without a trend. For that reason the charts compare observed over expected with the the reference period level, drawn as a dashed line, and not with 1.

Record highs and record lows combine the daily maximum and the daily minimum temperature. The level for each is the average of the two levels in the data. A value above the dashed line means more records than in the reference period; below it means fewer. The numbers show what was observed and how it compares. They do not say why.

The charts start in 1989. 51 earlier years are left out because too few records were expected from the few stations with a long enough record. The data download has every year.
