Best Time to Visit London (Month by Month)

By the Klemio team · Updated June 3, 2026

Go in May or September. That's the honest answer. The weather is at its most reliable, the parks are doing their thing, and you dodge both the summer crowds and the winter dark. Summer gets the headlines and the longest days, but it also gets the queues, the prices, and a Tube that turns into a sauna.

London's weather is a year-round gamble rather than a clean wet-and-dry split, so no month promises sun and no month is a washout either. Pack a layer and an umbrella whenever you come. What actually changes month to month is daylight, crowds, and price, and those swing hard.

The shoulder months (April to early June, and September to October) are the sweet spot: decent weather, manageable crowds, fairer hotel rates. Summer is peak on every axis. Winter is cheap and dark but has December's lights going for it. Pick based on whether you want long days or short queues, because you rarely get both.

Season by season

Spring

March to May
Weather
Mild and changeable, with the odd warm day and plenty of grey ones. Parks come into bloom, cherry blossom and daffodils by April. Carry a layer and an umbrella.
Crowds
Building. Quiet in early spring, then jumping over Easter and the late-May bank holidays when half-term and tourists arrive together.
Cost
Shoulder, edging toward peak by late May. Easter week spikes; the gaps between school holidays are the value windows.

May is arguably the best month London gets, with the parks green and the crowds not yet at their summer worst.

Summer

June to August
Weather
Warmest of the year and the longest days, with light past 9pm in June. Real heat is possible and the Tube has no air conditioning on most lines, which is genuinely unpleasant in a heatwave.
Crowds
Heavy. School holidays worldwide plus festival season mean the longest queues and the busiest sights of the year.
Cost
Peak. Hotels and flights are at their priciest, and the big events push them higher.

Long days and a packed events calendar, but the crowds, prices, and a sweltering Tube are the trade-off you're signing up for.

Fall

September to November
Weather
September often feels like a calmer extension of summer. It cools and dampens through October into a grey, wet November as the daylight drops off fast.
Crowds
Easing. September is still busy but better than August; by November the tourist numbers thin out noticeably.
Cost
Shoulder in September, then falling toward winter rates by November (October half-term is a brief spike).

September is the other great month to come, nearly summer's weather with a fraction of the hassle and lower prices.

Winter

December to February
Weather
Cold but rarely freezing, mostly grey and damp with short days (dark by mid-afternoon in December). Snow is uncommon. Wrap up and plan indoor-heavy days.
Crowds
Low except for the run-up to Christmas, when the lights and markets pull big weekend crowds into the West End. January and February are the quietest of the year.
Cost
Cheapest of the year in January and February. December is an exception, with Christmas pushing rates back up.

Cheap, dark, and quiet, redeemed by December's Christmas lights; January is for museum days and bargain hotels.

Month by month

January
Cold, grey, and the quietest month, with the lowest hotel prices of the year. Days are short, so plan indoor museum-heavy itineraries. The post-Christmas sales draw shoppers but the sights are calm.
February
Still cold and dark but cheap. Watch the February half-term week, when family attractions and trains get busy for a stretch. Otherwise a good month for crowd-free museums.
March
Spring starts to show but the weather is unreliable, swinging from mild to wintry. Crowds are still light early on. Easter sometimes lands late in the month and spikes prices and visitors.
April
Parks bloom and the city brightens, though showers are frequent. Easter and school holidays bring a crowd bump. The London Marathon late in the month closes central roads for a day.
May
One of the best months: mild, parks at their greenest, daylight stretching out. Two bank holidays bring busier weekends. Book ahead, since this is when smart travelers come.
June
Longest days of the year, light until past 9pm, and generally pleasant. Peak season starts in earnest. Wimbledon begins late in the month and books out hotels near the courts.
July
Warmest and busiest, with heatwaves possible and the Tube uncomfortable when it's hot. School holidays begin, so queues are at their longest. Book everything well ahead.
August
Hot, crowded, and pricey, the deepest part of peak season. The Notting Hill Carnival over the late-August bank holiday closes west London streets for a huge party. Sights are at their busiest.
September
The sweet spot: near-summer weather, thinning crowds, and lower prices as kids go back to school. Easily the best value-to-weather month of the year. Book sooner rather than later.
October
Cooler and wetter with daylight dropping fast, but pleasant and quieter. The October half-term week brings a short family-crowd spike. Good for indoor-and-outdoor mixed days.
November
Grey, damp, and dark, with the fewest tourists of the autumn. Bonfire Night on the 5th brings fireworks across the city. Christmas lights start switching on toward month's end.
December
Short, cold days but the city's most festive, with Christmas lights, markets, and ice rinks. The West End and shopping streets get crowded on weekends. Many sights have reduced hours around Christmas Day.
When we'd go

We'd go in late May or in September, and we'd lean September if forced to pick one. You get weather that's close to summer's best, the parks still looking good, daylight that lasts into the evening, and crowds and prices that have come off the August peak. May has the same appeal on the way up, with the bloom on and the heat not yet arrived. Both let you walk the city comfortably, get into the free museums without the worst queues, and not pay summer rates for a hotel. If your trip is fixed for summer, come in June rather than July or August, and brace for a hot Tube.

When to skip: Skip late July and August if you can help it: that's peak heat, peak crowds, and peak prices all at once, with a Tube that's miserable in a heatwave. Watch the school half-term weeks (February and late October) for short family-crowd spikes, and Easter week for a price jump.

Best time to visit London: FAQs

Late spring (May) and early autumn (September) are the best overall. You get good weather, longer days, and crowds and prices below the summer peak. September edges it for value as school holidays end.

January and February are the cheapest, with the lowest hotel rates and the thinnest crowds. The trade-off is cold, grey, short days, so plan indoor-heavy trips. December is the winter exception, with Christmas pushing prices back up.

Not bad, just the busiest and most expensive, with the longest queues and a hot, un-air-conditioned Tube during heatwaves. The long daylight is the real upside. If you must come in summer, June beats July and August.

Probably a little, whenever you come. London gets light, scattered rain year-round rather than a defined wet season, so pack an umbrella and a layer regardless of month. It rarely ruins a day.

Wimbledon (late June into July) fills hotels near the courts, Notting Hill Carnival (late-August bank holiday) closes west London, Bonfire Night (November 5) brings fireworks, and the Christmas season crowds the West End from late November.
