Country sees normal average temperature in April

The temperatures were normal in most parts of the country in April and in many places, the month was unusually rainy, according to the Finnish Meteorological Institute (FMI).

At the beginning and end of the month, the weather was clearly colder than usual, while after mid-April, there was an unusually warm period which lasted for about a week, said the FMI in a press release on Friday.

According to the statistics, the average temperature in April varied from approximately minus 3 degrees Celsius in Lapland’s northwestern “arm”, to +4 degrees Celsius in the Southwestern archipelago.

In the southern and central parts of the country, as well as in the western parts of Northern Ostrobothnia, April was about one degree colder than usual, whereas Lapland was, in general, about 0.5–1 degree warmer than usual.

The highest temperature of the month, 18.2 degrees Celsius, was recorded on 20 April at the Seinäjoki Pelmaa observation station. The lowest temperature of the month, minus 24.0 degrees Celsius, was recorded at Kevojärvi observation station in Kevo, Utsjoki, on 5 April.

April was unusually rainy in most parts of the country. In parts of Central Finland, even exceptionally rainy.

A significant proportion of the rainfall came in the early days of the month, as deep low pressure and snowfall moved across Finland to the north. As a result, over 30 centimetres of snow accumulated in many places of Pirkanmaa and Central Finland, in 48 hours.

The highest precipitation during the month was recorded at the Hyytiälä observation station in Juupajoki, 76.6 mm. The month’s highest amount of daily precipitation, 25.8 mm, was also measured in Juupajoki, on 4 April.

The regions of the eastern border, as well as Ostrobothnia experienced a month with less rain than usual. The lowest amount of precipitation during the month was 14.3 mm, measured at the Mekrijärvi observation station in Ilomantsi.

At the end of April, snow cover area extended from the northern parts of North Karelia and North Savo to Lapland.

In the southern and western parts of the country, most of the observation stations had no snow, but there were stations with snow up to 20–40 cm, in places. At the end of the month, the maximum snow depth was recorded at Kittilä Kenttärova observation station, 93 centimetres.
