Finland is still under the grip of a long stretch of hot weather, and according to forecasts, it is not easing anytime soon. The Finnish Meteorological Institute confirmed that the Finland heatwave will likely continue through the weekend and stretch into the early part of next week.
Temperatures are expected to stay consistently above 25°C in nearly all parts of the country until at least Tuesday. For some areas, especially in the southeast, the heat is holding stronger and may persist even longer.
The ongoing heat has already lasted more than two weeks. If it holds steady through Monday, Finland will have experienced 18 straight days of unusually high temperatures. Although intense, this does not yet break the 1973 record, when the country faced 38 consecutive days of hot weather.
Meteorologist Vendi Pelkonen from the Finnish Meteorological Institute explained that southeastern Finland has the highest likelihood of continued heat, while other regions may soon begin to cool.
By midweek, weather models show a change. Rain showers and isolated thunderstorms are expected to roll in across different parts of the country starting Thursday. This may offer a short-lived drop in temperatures, especially in areas that receive rain.
“If the rain comes, it could cool things temporarily to somewhere between 20 and 25 degrees,” Pelkonen said. “But where there is no rain, the high temperatures may still sit between 25 and 30 degrees.”
Lapland is expected to be the first region to cool, with a noticeable drop to around 20°C by Wednesday or Thursday. After that, a gradual cooldown will follow across central and southern Finland as the heat begins to lose its grip.
By the middle of next week, conditions across most of Finland are predicted to return to more typical seasonal levels, with temperatures ranging from 17 to 22 degrees.
Even with the expected shift, sudden downpours, humidity, and quick changes in pressure could still cause some discomfort during the transition. Pelkonen added that the air might remain sticky and the atmosphere unstable for a few days, which could make conditions feel warmer than they are.
