In 2012, the national summer mean temperature was 0.4 °C below the long term average. This was the coolest summer since 2008. There were a total of 18 hot days (daily maximum above 25 °C) which is well below average. The highest temperature was 31.0 °C in Lieksa on July 30th.

In some areas of eastern Finland the summer precipitation was over 1.5 times the long term average. The highest precipitation total for the three months was 424 mm at Tohmajärvi. In Lapland and most of southern Finland there was less precipitation than usual.

During the period between May-August only 75 000 lightning strikes were recorded. This is roughly half of the usual number of strikes in Finland.

A fairly typical August
