Tallinn vs Tromsø

Tallinn

Tallinn has a humid continental climate moderated by its Gulf of Finland coastline. Summers are mild and pleasantly long with up to 18 hours of daylight in June. Winters are cold, dark, and occasionally dramatic — the sea can partially freeze and the Old Town under snow is spectacular but icy. The transitional seasons are short. Northern lights are visible on clear nights from November through March.

Tromsø

Tromsø has a subarctic maritime climate — remarkably mild for its latitude thanks to the North Atlantic Current, but defined year-round by dramatic daylight extremes. Snow falls heavily from November through April. Summer temperatures rarely exceed 20°C. Winter lows typically hover between −5 and −10°C — cold but manageable in proper layers. What you plan for is light, not cold.

Tallinn

Tallinn has excellent public transport covering the whole city by tram, trolleybus, and bus. Public transport is completely free for registered residents — one of only a handful of cities in the world to have made this permanent policy since 2013. Tourists pay, but fares are very cheap. The Old Town is entirely walkable. Bolt (founded in Tallinn) makes taxis among the cheapest and most transparent in Europe.

Walkability: The Old Town and adjacent districts are highly walkable on flat ground, though Toompea Hill involves a moderate climb. Cobblestones in the Old Town can be tough with luggage — rolling bags struggle. Winter icing significantly affects walkability. Overall the city is compact and pedestrian-friendly for its size.

Tromsø

Tromsø is a small island city — most sights are within walking distance in the city centre. The local bus system (Troms Fylkestrafikk) covers the island and the mainland, including the airport. Taxis are readily available; ride-hailing is limited. For excursions outside the city (dog sledding at Camp Tamok, Sommarøy fishing village, reindeer camps), a tour bus or rental car is essential.

Walkability: City centre is highly walkable and concentrated. The island of Tromsøya itself is 9 km long but the useful tourist zone is just 2 km of it. Outside the island — mainland, Kvaløya, or further afield — you need bus, taxi, or car.
