London in summer is wonderful — long evenings, parks in bloom, festivals — but a hot day with luggage and unfamiliar transport can wear a visitor down fast. This guide helps you see the city comfortably, with the coolest ways to get around and practical tips for travelling in the heat.
Plan around the heat
The sun is strongest from late morning to mid-afternoon. Front-load outdoor sightseeing to the morning, save air-conditioned museums and galleries for the hottest hours, and enjoy the long evenings when it cools. Carry water, wear a hat and sunscreen, and don’t underestimate how tiring heat plus walking plus jet lag can be.
Cool places to spend the hottest hours
- Major museums & galleries — the British Museum, Tate, the V&A: cultural and cool
- Shaded parks — the tree-lined stretches of Hyde Park, Regent’s Park, Greenwich
- River breezes — a Thames walk or boat catches what air there is
- Indoor markets & arcades — browse out of the sun
The coolest way to get around
For visitors, London’s transport is the summer wildcard. The deep Tube lines are hot and confusing with luggage; buses are slow in traffic. For arrivals, days out and anything with cases, a fixed-fare air-conditioned taxi is the comfortable choice — door to door, cooled, and pre-cooled on request. International visitors can even book in their own language. See the full hot-day transport comparison.
Tips for families and groups
Travelling with children or in a group multiplies the summer challenge — tired kids, more luggage, splitting across hot Tube carriages. One family car or minibus keeps everyone together in the cool, with free child seats, and often costs less per head than the alternatives. From the airport, it’s the calmest possible start to a summer trip.
