# Finland summer weather outlook > Live situation record from CLSTR: https://clstr.news/situations/finland-weekend-weather-forecasts > Updated: 2026-08-11T03:33:27.000Z. Sources: 10. Developments: 9. In early August, a warm air mass from southern Sweden was forecast to bring temperatures near 23 °C to the south, though conditions remained unsettled with alternating sunshine and rain. Heavy showers and possible thunderstorms were expected in central and northern regions, including Lapland, with daily rainfall totals exceeding 10 mm in some areas. By the weekend of August 8, a temporary cooling period preceded a return to summer-like heat. Forecasts indicated potential heatwave conditions in the south, with temperatures reaching 18–24 °C on Sunday. While the south and central regions saw clearer skies, the north faced unsettled weather with rain and thunder. Gusty winds were expected, particularly on the Gulf of Bothnia, where gusts could reach 15 m/s. A low-pressure system arriving the following Monday was projected to bring wetter weather and stronger winds, posing a risk of isolated tree falls. Long-term outlooks for the remainder of August suggest a trend toward cooler and wetter conditions than average. Meteorologist Joanna Rinne noted that high-pressure systems over Central and Western Europe are driving cool air from the west into the Fennoscandian region, preventing heat-inducing high-pressure situations from forming over Finland. While a brief warm spell might bring temperatures above 20 °C to the south toward the end of the week, significant heatwaves are not expected, and increased rainfall is projected to persist through the latter half of the month. ## Timeline ### 2026-08-11: Finland weather forecast predicts cool and rainy August Finland is expected to experience cooler and wetter weather than usual for the rest of August, as high-pressure systems in Western Europe drive cool air into the region. 2 sources. https://clstr.news/cluster/finland-weather-forecast-predicts-cool-and-rainy-august ### 2026-08-08: Finland weather forecast: heatwave expected this weekend Finland's weather will see a brief mid-week cooldown before temperatures rise again, with heatwave conditions and gusty winds forecast for the upcoming weekend. 3 sources. https://clstr.news/cluster/finland-weather-forecast-heatwave-expected-this-weekend ### 2026-08-02: Finland sees mixed sunshine and showers as mid‑week temperatures rise Finland will experience a warm spell with temperatures up to 23 °C in the south, alternating sunshine and showers, especially heavy in the north and central regions, through the week. 2 sources. https://clstr.news/cluster/finland-sees-mixed-sunshine-and-showers-as-midweek-temperatures-rise ### 2026-07-23: Finland sees mixed weekend weather with rain and warming temperatures Finland’s weekend forecast shows rain in the west and north, sunny east, temperatures 15‑20 °C (over 20 °C possible east), no night frost, and stronger winds. 2 sources. https://clstr.news/cluster/finland-sees-mixed-weekend-weather-with-rain-and-warming-temperatures ### 2026-07-19: Finland experiences exceptional cold spell as meteorologists warn of lingering low temperatures Finland faces a rare cold snap with highs near 14‑15 °C, a blocked weather pattern, and a possible warm shift in late July amid high forecast uncertainty. 3 sources. https://clstr.news/cluster/finland-experiences-exceptional-cold-spell-as-meteorologists-warn-of-lingering-low-temperatures ### 2026-06-28: Finland sees warm start to July before rain and thunderstorms move in mid‑week Finland begins July with near‑30 °C heat and sunshine, then faces rain and thunderstorms from Thursday, cooling temperatures across the country. 2 sources. https://clstr.news/cluster/finland-sees-warm-start-to-july-before-rain-and-thunderstorms-move-in-midweek ### 2026-06-12: Finland faces weekend summer storm with heavy rain and strong winds Finland will experience a weekend summer storm with heavy rain, temperatures 10‑20 °C, and strong winds up to 15 m s⁻¹, especially on the western coast. 3 sources. https://clstr.news/cluster/finland-faces-weekend-summer-storm-with-heavy-rain-and-strong-winds ### 2026-06-05: Finland braces for rainy, windy weekend as low pressure moves in A southern low‑pressure system will bring rain and gusty winds to western Finland and Åland on Saturday, with temperatures 15‑25 °C; Sunday clears up, while early next week remains warm with scattered showers, 2 sources. https://clstr.news/cluster/finland-braces-for-rainy-windy-weekend-as-low-pressure-moves-in ### 2026-05-29: Finland expects warm, sunny weekend with clouds and showers in the north Finland will have a warm, mostly sunny Saturday (18‑21 °C) with clouds and light rain in the north and east, followed by a cloudier Sunday and scattered showers early next week, with temperatures rising toward 3 sources. https://clstr.news/cluster/finland-expects-warm-sunny-weekend-with-clouds-and-showers-in-the-north --- Cite as: Finland summer weather outlook.
