London in summer
London is the fallback that always works: the cheapest flights in Europe, world-class museums that are free, and long summer evenings in the parks. It is the one destination here with no real off-season.
Best time to go
June and July for the longest days and warmest weather; May and September for lower hotel prices.
Peak season heat
Rarely an issue — mid-20s°C is typical, with occasional short heatwaves and limited air conditioning.
Nearest airports
Heathrow (LHR), Gatwick (LGW), Stansted (STN), Luton (LTN) and City (LCY) — compare all five, the fare gap is often large.

London FAQ
Is London worth it in summer?
Yes — it has the longest daylight of any destination on this list, free museums, and park culture that only works in summer. Hotels are the expensive part; book early or stay slightly outside zone 1.
Which London airport is cheapest?
Stansted and Luton usually carry the lowest fares, but factor in 60–90 minutes and a coach or train ticket into the city before comparing with Heathrow or Gatwick.
