Daylight hours decrease, starting around 13-14 hours in early September and shortening to 11-12 hours by month’s end.

What Should I Expect Regarding Crowds and Events? Crowds are noticeably thinner than during the peak summer months, as local holidays end and residents return to work and school. This means less congestion at popular attractions. Helsinki often hosts cultural events in September, including Helsinki Design Week (typically early September). The city embraces the autumn, with changing foliage and crisp air. Many attractions continue with summer opening hours initially, but some may transition to autumn schedules later in the month, so always check in advance.
