Helsinki is a modern pocket-sized metropolis, one of the world's most livable cities with 450 years of history. It's famous for its design, and for combining cultural influences from both East and West. It's currently host to five Michelin-starred restaurants, and it's fronted by one of the largest sea fortresses in the world. It's a small, intimate city with something for everyone.
A Worldcon in Helsinki would be the northernmost Worldcon yet, at 60°N. It would therefore also be the sunniest Worldcon, with approximately 17-hour long days and nights never going past twilight. July and August are the best time to visit Helsinki, with average temperatures ranging from 13°C (55°F) at night to 22°C (72°F) during the day.
