Oslo vs Valletta

Oslo

Oslo has a humid continental climate, though the Gulf Stream moderates temperatures considerably compared to other cities at the same latitude. Summers are genuinely warm and glorious, with up to 19 hours of daylight in June. Winters are cold and dark — only 6 hours of daylight in December — but snowfall and Christmas market season make them atmospheric. The aurora borealis (Northern Lights) is occasionally visible from Oslo on clear, dark winter nights, though you'll see them far better further north. Spring arrives late but emphatically; autumn is crisp and colorful.

Valletta

Valletta has a classic Mediterranean climate — long, hot, dry summers and short, mild, rainy winters. The city sits on an exposed peninsula surrounded by water on three sides, which moderates temperatures but also means the wind can be relentless. Malta averages around 3,000 hours of sunshine a year, one of the highest totals in Europe.

Oslo

Oslo has an excellent public transit system operated by Ruter, covering the T-bane (metro), tram, bus, commuter train, and harbor ferry lines under a single unified ticket. A single trip costs NOK 46 (~$4.25); a 24-hour day pass costs NOK 130 (~$12), and a 72-hour pass NOK 230 (~$21). The Oslo Pass (NOK 495/24h, NOK 695/48h, NOK 845/72h) includes unlimited Ruter transit plus free entry to most major museums — worth calculating based on your itinerary. The city center is compact and very walkable. Cycling is excellent and Oslo Bysykkel (city bikes) are available via app for NOK 49/month or NOK 49 per 45-minute trip.

Walkability: Oslo's city center is compact and extremely walkable. The Opera House, Akershus Fortress, Aker Brygge, Karl Johans gate, and the Royal Palace form a walkable central core within about 2.5 km. Vigeland Park is a comfortable 30-minute walk or 10-minute tram ride. Bygdøy peninsula requires a ferry or bus in summer. Holmenkollen requires the T-bane metro.

Valletta

Valletta itself is entirely walkable — the whole peninsula is well under 1 km long and cars are largely banned inside the walls. For the rest of the island, Malta Public Transport runs an efficient and cheap bus network radiating out from the Valletta terminus just outside the City Gate. Ferries, water taxis, and taxis fill the gaps.

Walkability: Valletta itself is perfectly walkable — the whole old city fits within a 0.8 km² fortified grid. However the cross streets running down to the bastions are extremely steep and stepped in places, which is physically harder than the gentle distances suggest. Comfortable shoes with grip are essential, especially on the limestone paving.
