May, June and September for the balance, September for value, early December for the lights, January for the bargains. Here is how each month really feels, and how to plan the day you land.
May, June and September give you the best balance of weather, daylight and crowds. September is the pick if you care about price. Early December is the pick if you want the Christmas lights. January and February are the pick if you want London cheap and quiet, and you do not mind 4°C and rain.
| Season | Weather | Crowds | Hotel prices | Best for |
|---|---|---|---|---|
| Spring (Mar to May) | 5 to 17°C, parks in bloom | low to moderate | good value | sightseeing, gardens, the Boat Race |
| Summer (Jun to Aug) | 12 to 23°C, long evenings | very high | peak | Wimbledon, outdoor London, families in school holidays |
| Autumn (Sep to Oct) | 10 to 20°C, some rain | moderate | mid-range | exhibitions, festivals, food, fewer queues |
| Winter (Nov to Feb) | 2 to 9°C, short days | lowest, except Christmas week | cheapest, except Christmas week | lights, theatre, museums, afternoon tea |
January and February are cold, dark by 16:30 and cheap. The January sales, museum blockbusters and empty restaurant tables are the reward. March and April warm up quickly; Easter week is busy, the rest is quiet and the parks are at their best from mid April. May is the first month you can rely on eating outside, with the Chelsea Flower Show and two bank holidays. June is the sweet spot for weather, but prices step up and Wimbledon at the end of the month fills west London hotels.
July and August are peak season: 23°C or hotter, 16 hours of light, and queues at everything. Book timed tickets or skip the big three. September is the locals' favourite: 19 to 20°C, the August crowds gone, the autumn exhibitions opening (the Bayeux Tapestry at the British Museum in 2026) and free festivals such as Open House and Totally Thames. October brings the Film Festival, half term and the first proper rain. November is the cheapest month of all and the lights switch on mid-month. December is magical and expensive, and there is no public transport at all on Christmas Day, so plan your airport journey around it.
Whatever month you choose, the day you land is the one most visitors get wrong. A transatlantic flight into Heathrow at 06:30 means immigration, luggage and a 45 to 90 minute transfer before you are even at the hotel, and check-in is rarely before 14:00. Give yourself an easy first day: drop the bags, walk the South Bank, eat early.
Two things make the transfer easier. First, book a car that is tracking your flight so a delay costs you nothing; our drivers meet you in the arrivals hall with a name board and waiting time is included. Second, avoid the midweek morning rush if you can: London's rush hour is now concentrated on Tuesday to Thursday, with 08:00 to 08:30 the worst half hour, and road journeys into central London take up to twice as long then. Fixed prices from every airport are on our route pages: Heathrow to central London, Gatwick to London, Stansted to London, Luton to London and London City Airport.
Terminal confirmed from your flight number, pickup timed backwards from check-in or tracked forward from landing, name board standing where you exit — London's entire airport system run the way it should have always worked. Sixty seconds books any of it.
