The start of the thermal spring in Finland is behind the average. When the thermal spring begins, the rest of the snow usually melts quickly.
During Easter, sunny and warm days are enjoyed all over Finland.
The Finnish Meteorological Institute has stated that the institute does not predict the arrival of thermal spring in advance.
According to Jokis, the onset of thermal spring in all of Finland usually lasts about a month. According to statistics, thermal spring has often started on the southern coast of Finland in the last week of March. The thermal spring in Oulu has reached the second week of April, and finally spring has started in Northern Lapland at the end of April.
So the thermal spring is starting late.
Jokinen reminds us that thermal spring is ultimately only about temperatures.
– Everyone can define spring in their own way. For example, migratory birds and plants can have their own schedule.
However, the thermal spring is usually visible at least as the snow piles shrink. Night frosts slow down the melting of snow. When the thermal spring begins, the melting of the snow does not stop even at night.
