September weather was exceptional, according to the Finnish Meteorological Institute’s records.

Temperatures stayed high across most of the country with the south in particular enjoying average highs of +14°C, although Lapland had some normal temperatures of +8°C.

The averages – apart from the north – were about +1°C to +3°C warmer than usual, an event that happens only once every ten to 30 years according to FMI’s statistics.

Weather in September came in two parts: the first half of the month was particularly warm with a peak of +26.1°C. But at the latter half of the month, Storm Kuisma swept over the country and lowered the temperatures a bit.

That September high confirmed 2018 as the second warmest summer since more than 15 years. This year we had 64 days where the mercury hit +25°C and back in 2002 there were 65 days.

Rain dampened the country

Although September’s temperatures were warmer than usual, there was also quite a bit of rain, especially from South Karelia to Lapland.

The highest single rainfall of 148mm was measured at Koivuniemi in Kymenlaakso.
