Meteorologists have been saying that the month of May, which will comes to a close at the end of this week, will likely be the warmest Finland has ever experienced, since the country began officially recording the weather.
Sunday's temperatures in the far south of the country are expected to reach a high of about 21 degrees Celsius, while in central areas highs of 13-16 degrees are expected. In the far north on Sunday, the mercury will reach around nine degrees.
Summer temps return Monday
However, warm air arriving from the south will bring temperatures to at least 19 degrees across the entire country. It will be warmest in southern Finland, with highs of 23-25 degrees expected on Monday.
It will also be very sunny in about half the country, areas north of central Finland - as well as some eastern sections - will be cloudier, but nearly as warm as the south, according to the Finnish Metrological Institute (FMI).
Finland's relatively hot weather will continue on Tuesday in much of the county, but showers are expected in parts of Lapland. Temperatures, however, will be similar to Monday's, according to FMI.
