The best time to go to London, England is May or September for most travelers. Both months give you mild weather, long-enough days, open-air events, and easier hotel availability than the main summer rush.
June is also a strong pick if you want the longest evenings. July and August bring the warmest weather, but they also bring school-holiday crowds, higher room rates, and busy museum lines. December is a special case: not the best weather, but one of the most atmospheric times for lights, markets, shop windows, and theater.
Best Months For London Weather And Value
May and September give London the cleanest balance of weather, cost, and comfort. May leans greener and brighter; September feels calmer after the school-holiday rush.
London never gives you a fully dry season, so the smart play is not chasing perfect weather. Pick a month with mild temperatures, decent daylight, and enough indoor backups to make a rainy afternoon painless.
- Pick May for parks, gardens, spring events, and temperatures that are usually pleasant for walking.
- Pick September for fewer family crowds, good museum days, and evenings that still work for dinner outside.
- Pick June if daylight matters most; sunset comes late, and you can fit more into each day.
- Pick December for holiday atmosphere, not weather or low prices.
Going To London By Season: What Each Month Feels Like
London’s travel seasons are softer than many European cities because museums, theaters, pubs, markets, and shops work year-round. Weather changes the rhythm of the trip more than the list of things you can do.
The month-by-month table below uses rounded London Heathrow climate averages, with Fahrenheit added for US planning. The official station data comes from the Met Office London Heathrow climate averages.
| Month | Typical Weather | Travel Value |
|---|---|---|
| January | About 47°F highs, short days, roughly 12 wet days | Lower prices after New Year, but daylight is limited |
| February | About 48°F highs, cold mornings, around 10 wet days | Good for museums, theater, and cheaper rooms |
| March | About 53°F highs, brighter days, lighter rain totals | Shoulder-season value with spring starting to show |
| April | About 59°F highs, longer days, changeable weather | Good walking month if you pack layers |
| May | About 65°F highs, long evenings, around 8 wet days | Best all-round month for parks, neighborhoods, and value |
| June | About 71°F highs, longest daylight, around 8 wet days | Excellent weather, with prices rising toward summer |
| July | About 75°F highs, warmest month, around 8 wet days | Great for outdoor plans, busiest for families |

How Crowded Is London In Summer?
London is busiest from late June through August, with July usually feeling the most crowded around Westminster, the British Museum, Tower Bridge, and Covent Garden. Summer is still worth it if you book early and start popular sights in the morning.
The main summer issue is not only crowd size. Hotel choice tightens, family attractions fill, and trains for day trips to Windsor, Oxford, Bath, and Brighton sell more seats. If your dates are fixed in July or August, stay near the Tube line you will use most and reserve timed-entry sights early.
For travelers with flexible dates, early June and mid-September often feel better than August. You still get usable evenings, but you avoid the thickest school-holiday pressure.
Cheapest Time To Fly And Stay In London
January, February, and parts of November are usually the easiest months to find lower airfare and hotel rates in London. The trade is cold weather, shorter days, and fewer outdoor meals.
For a value trip, aim for weekdays outside holiday weeks and major event spikes. Flights can swing sharply by airport, so compare London Heathrow Airport, London Gatwick Airport, and nearby arrival options before locking dates.
Once your month is set, compare flights into London before choosing your hotel area:
Where To Stay For Your Chosen Month
London’s best area depends on your month and your main plans. First-timers usually do well in Covent Garden, South Bank, Westminster, Bloomsbury, or Marylebone because those areas cut transit time across a short trip.
In May, June, and September, staying near Hyde Park, Kensington Gardens, Regent’s Park, or the South Bank gives you more easy outdoor time. In winter, prioritize Tube access, theaters, museums, and restaurants over park access.
Rain-proof rule: In any month, a hotel within a five-minute walk of a Tube station is more useful than a slightly prettier street ten minutes farther out.
Use the map to compare central areas and see whether a cheaper room sits near a Tube line or too far from the sights:
Best Time For Sights, Parks, And Day Trips
May through September is the strongest window for London’s parks, river walks, open-air markets, and easy day trips. October can also work well for museums and neighborhoods, but build more indoor time into the plan.
For classic sightseeing, split outdoor-heavy days and indoor-heavy days so weather does not wreck the schedule. A good three-day rhythm looks like this:
- Day 1: Westminster, St James’s Park, the South Bank, and a theater night.
- Day 2: Tower of London, Tower Bridge, Borough Market, and the Thames path.
- Day 3: British Museum or Victoria and Albert Museum, then Notting Hill, Marylebone, or Greenwich.
Guided walks and day trips are easiest to fit in May, June, and September, when daylight supports a full schedule without the heaviest summer pressure:
What Month Should You Pick For Your Trip?
Choose May if you want the best single answer for London weather, parks, and value. Choose September if you want similar comfort with fewer school-holiday crowds.
Use these final picks to match the month to the trip you actually want:
- Best all-round month: May, especially for a first London trip with parks, museums, and neighborhoods.
- Best calmer warm month: September, especially for couples and adults traveling without school schedules.
- Best for long days: June, when evenings stretch late enough for busy sightseeing.
- Best for lowest prices: January or February, as long as indoor sights are the focus.
- Best for holiday atmosphere: December, especially before Christmas week gets expensive.
- Best month to avoid: August, unless school holidays or warmest weather matter more than crowds.
For most visitors, May wins by a small margin. London feels open, green, and easy to move through, and the weather is mild enough to enjoy the city without planning every hour around rain or heat.
