London vs Rotterdam

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.

Rotterdam

Temperate maritime climate — mild but grey. Notoriously windy (the port effect). Rain is possible any month. Summer is pleasant but brief; winter is cold and overcast.

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.

Rotterdam

Rotterdam has an excellent RET transit network (metro, tram, bus). OV-chipkaart or contactless card for all transit. The city is also extremely cycle-friendly.

Walkability: Very walkable in the city center; Cube Houses, Markthal, and Erasmus Bridge all within easy walking distance of each other
