Finland autumn weather transition and forecast

Overview

Following a period of high weather volatility in mid-to-late summer, the weather outlook for late September 2026 indicates a transition into autumn.

Forecasts predict pleasant conditions at the start of the week, with sunshine and temperatures between 10 and 15 °C. A strengthening high-pressure system is expected to bring dry conditions across the country by Tuesday. While southern regions may see early rain showers and thunderstorms, the middle and northern parts of Finland are expected to see breaks in the weather following recent rainfall.

Although sunny intervals are anticipated through Wednesday, the risk of rain is expected to increase nationwide starting Thursday, though temperatures are likely to remain stable.
