In January and February, the average temperature hovers around −4 °C, thanks to the mitigating influence of the Baltic Sea and the North Atlantic Current. This maritime influence helps to moderate the weather and keep the temperatures from plummeting too low.

Interestingly, Helsinki’s winters are noticeably warmer than those in the northern regions of Finland. This can be attributed to its extreme Southern Finland location and the urban heat island effect.

As spring approaches, the city transitions into a season of renewal, with the temperatures slowly rising and nature coming back to life. The snow season in Helsinki is comparatively shorter than in other areas of Finland, thanks to its milder climate.

While Helsinki does experience occasional dips in temperature below −20 °C, such occurrences are relatively infrequent. Overall, the climate in Helsinki offers a pleasant balance between chilly winters and comfortable summers.

Whether you visit in the spring, summer, or winter, Helsinki’s climate ensures that you can enjoy the city’s beauty and attractions throughout the year.
