A short burst of summer heat is expected to hit Finland this weekend, with the highest temperatures forecast for Sunday. According to the Finnish Meteorological Institute, southern and central parts of the country may see temperatures rise to 26–27°C.
The warm spell marks a break from the cooler early summer conditions, but meteorologist Jouko Korhonen said it will be brief. “It’s not a heatwave, just a one-day spike,” he said.
On Sunday, the heat will likely reach the coast, including central Helsinki. The most reliable warm readings are expected from northern Vantaa onwards. In contrast, temperatures in northern Lapland will remain around 10°C. “The difference between north and south will be considerable,” Korhonen added.
Friday could see temperatures exceed 20°C on the south coast. On Saturday, sunshine will extend across much of Finland, including parts of central Lapland. Temperatures may reach up to 25°C in areas like Vantaa, with slightly lower readings further north.
While Saturday’s conditions may approach the heat threshold in parts of Tornio River Valley, Jyväskylä, Vaasa, and inland areas of South Ostrobothnia and Satakunta, the clearest signs of heat are expected on Sunday.
Uusimaa may see the heat threshold broken in locations such as Vihti and Mäntsälä. “Or rather, not broken like frost—surpassed,” Korhonen clarified.
Monday could bring continued heat in some areas, but rain showers will become increasingly likely as the day progresses. These showers are expected to move east across the country by Tuesday.
From Tuesday onward, the forecast up to Midsummer points to “classically unsettled weather.” Temperatures could reach 20°C in dry areas but drop to 12–14°C in rainy regions.
Korhonen was cautious in making predictions about Midsummer weather. “The forecast changes twice a day. There are still seven days to go—so 14 forecasts left,” he noted.
