London vs Vienna

London

London's reputation for rain is somewhat exaggerated — it actually receives less annual rainfall than Sydney, Rome, or New York. However, drizzle is frequent and skies are often overcast. Pack layers and a waterproof jacket regardless of season.

Vienna

Vienna has a continental climate with cold winters, warm summers, and distinct seasons. Spring and autumn are mild but changeable. Summers can be hot, while winter occasionally brings snow to the city.

London

London's transport network (TfL) is extensive and efficient. Use a contactless bank card or Oyster card for the best fares — a daily cap of £8.10 (Zone 1-2) means you'll never overpay. Paper tickets cost significantly more. The Tube is the backbone, but buses and walking are often better for seeing the city.

Walkability: Central London is very walkable and walking is often faster than the Tube for short distances. The South Bank riverside walk from Westminster to Tower Bridge is one of Europe's best urban walks. Green parks (Hyde Park, St. James's Park, Regent's Park) connect neighborhoods beautifully on foot.

Vienna

Vienna has an excellent, integrated public transit system run by Wiener Linien covering U-Bahn (metro), trams, and buses. The network is clean, punctual, and runs late on weekends. A 24-hour pass is just eight euros and covers all modes.

Walkability: The historic center (Innere Stadt) is compact and highly walkable, with most major sights within a 20-minute walk of Stephansplatz. The Ringstrasse boulevard encircling the old city is about 5 km and makes a pleasant walk or tram ride.
