What's the Weather like in Helsinki in September 

Temperature

Following a mild summer, autumn reaches Helsinki early in September, with average daily temperatures around 10°C. A beautiful and brisk season, the average high during this month is 14°C, while the lows dip down to 6°C. September ties with November for the second rainiest month, receiving an average of 80mm of rain, and typically seeing 15 rainy days throughout the month.

Average Sea Temperature

This coastal city begins to experience a drop in sea temperatures, going from its highest point at 13°C in August to 10°C in September. The area will continue to cool down heading into October as the cold winter edges closer.

Sunshine Hours

The sun also begins to set more rapidly in the far northern capital. Daylight hours drop from more than 14 hours at the beginning of the month to only 11 hours and 30 minutes. The sunrise inches up from 6:15 to 7:20, while the sunset drops from 20:30 to 19:00 by the end of the month.

Cloud

Skies remain only partly cloudy though, allowing visitors to enjoy as much of the sun as possible.

Wind

Humidity is low considering Helsinki's seaside location. Wind speeds during September average around 14.5 km/hour. Tourism begins to slow down during this month, especially as students in many parts of the world are back in school. Visitors who don't mind bringing an extra jacket will find there's still plenty to enjoy in this beautiful city during its cool autumn weather.

Things to do in Helsinki in September 

Helsinki Music Center

The Helsinki Music Center, or Musiikkitalo, is home to a concert hall, the Sibelius Academy, and two symphony orchestras. Located in the Töölönlahti, the prestigious site is just acorss the street from the Parliament of Finland. The main concert hall seats more than 1,700 people, and five smaller rooms can hold between 140 and 400 guests. A chamber music hall, opera hall, organ hall, rehearsal hall, and other music rooms make up the building. Tourists are welcome to visit the building at any time and explore the foyers, cafe and restaurant. With luck, one might catch a bit of music from a Sibelius Academy student using a practice room.

Crussell Bridge

The beautiful Crusell Bridge is a symbol of Helsinki, crossing the Ruoholahti Bay in the Baltic Sea. A cable-stayed bridge, it was inaugurated in June 2011 and named after Finnish composer and clarinet player Bernhard Henrik Crusell. The beautiful canal area is just one of many spots around Helsinki to enjoy a walk along the water in the brisk autumn weather.

Market Square

Located on one end of Esplanadi Park near the South Harbor, the Market Square is a bustling outdoor marketplace that braves the weather throughout the year. One of the most popular market squares in the city, booths sell traditional market foods and treats, as well as locally made crafts and souvenirs. Heated cafe tents offer warm cups of coffee on cold autumn days. The area is surrounded by beautiful Finnish architecture and also serves as a launching point for ferries headed to tourist sites like Suomenlinna Fortress and other nearby islands, making Market Square the perfect start to a busy day of touring.

History

History buffs should head to Helsinki Cathedral, where a statue of Alexander II stands proudly in front. The Tsar of Russia and Grand Duke of Finland, he was assassinated in 1881. The statue was commissioned three years later and was completed in 1894. Walter Runeberg created the figure and added symbols on its pedestal to represent law, light, peace and work. Today the statue is a reminder of Finland's long and complicated history with Russia.
