On Sunday, Finland broke its record for the highest number of 'hot' days for the fourth consecutive day, as temperatures exceeded the official 'heatwave' threshold of 25 degrees Celsius for the 69th time this year, according to the Finnish Meteorological Institute (FMI).
The mercury climbed to 25.2 degrees in Rauma on the west coast, according to the FMI. A day earlier, it reached 25.6 degrees in the southwestern municipality of Salo.
With six above-25-degree days so far, this September has broken the 1968 record for the most 'hot' autumn days.
Temperatures could again top the 25-degree mark on Monday in some areas.
Clear, unseasonably warm conditions are set to continue throughout the country until Tuesday afternoon, when rain moves in from the southwest. Elsewhere, it should remain sunny until Wednesday or Thursday.
Warm temperatures are projected to continue well into next week at least.
There are warnings of wildfire risk in North and South Karelia and of strong winds on southwest sea districts - as well as on land in western Finland on Monday, with gusts of up to 15 metres a second possible.
