Cooler air is streaming into Finland from the north on Wednesday and Thursday. Conditions will be windy especially up north, with strong gusts in some areas. Light showers may appear in the east and north.
Temperatures are set to rise again heading into the weekend to 20-25 degrees Celsius in southern and central Finland, possibly accompanied by showers in some areas, says Yle meteorologist Kerttu Kotakorpi.
In the north, more unstable conditions will prevail, with temperatures of 10-20 degrees.
Temperatures to drop on Saturday
On Saturday, when most schools mark the end of term, temperatures will be over 25 degrees through much of the country, in some parts approaching or reaching 30 degrees. Up north, though, the mercury may remain in the upper teens.
“The highest risk of showers is in the east, with the sunniest skies probably along the coast,” says Kotakorpi.
Sunday could be even hotter than Saturday in southern areas, but cooler elsewhere.
“In the southernmost areas it could be 25-29 degrees, in Lapland (North) 5-15 degrees and in the rest of the country somewhere in between,” she predicts.
Cooling off to start June
The first week of June is set to bring significantly cooler weather. That follows one of the hottest months of May ever recorded in Finland.
The long-term forecast suggests that southern Finland should have readings of 10-15 degrees next week, with chillier air flowing in from the north and some rain in the forecast.
“Although the weather will cool off, temperatures should only be a few degrees cooler than average for June,” notes Kotakorpi.
Fire, wind and water warnings
The Finnish Meteorological Institute’s long-term forecast shows little chance of significant rain for at least the next 10 days in the Uusimaa region, which includes Helsinki.
It warns of extremely dry conditions throughout the country, with a nationwide forest fire alert in effect. In the Pirkanmaa region, the risk is at the highest possible level of 6, with levels close to that elsewhere in southern and central Finland.
There is also a shipping warning of low water levels in the Archipelago Sea, which may cause problems for cargo transport, as well as strong winds on most maritime districts.
The institute also warns of wind gusts of 15 metres per second in Lapland, which could cause fallen trees and electricity outages.
