Best Time to Visit London 2026: Month-by-Month Weather, Crowds & Prices
By Ziv Shay · 2026-05-24 · attractionscout
When Is the Best Time to Visit London?
The best time to visit London is late spring (May) and early autumn (September), when daytime temperatures sit at a comfortable 15–20°C (59–68°F), daylight stretches past 14 hours, and hotel rates run 25–35% below the July–August peak. If your only goal is warm weather and long evenings, July is the sunniest month. If you want the lowest prices, January and February deliver mid-range hotel rooms for £90–£140 a night — roughly half the summer rate — in exchange for cold, short days.
London is a true year-round city: museums, theatre, and indoor attractions never close for season, and the famous rain is steadier and lighter than its reputation (the city averages about 600mm a year — less than Rome or New York). That means your decision is less about "good weather vs. bad" and more about balancing crowds, cost, and daylight. Below is a month-by-month breakdown with real numbers so you can pick the trade-off that fits your trip.

| December | 8°C / 46°F | 3°C / 37°F | 55mm | ~7.5 hrs | High (holidays) |
Notice that rainfall barely changes from month to month — London's reputation comes from frequent drizzle and grey skies, not heavy downpours. October is actually the wettest month at ~69mm. Pack a compact umbrella or a light waterproof jacket no matter when you visit.
The Best Time to Visit London for Good Weather
June through August is London's warmest and sunniest stretch. July tops out at an average high of 23°C (73°F), and on a heatwave day the city can hit 30°C+ — worth knowing because most older hotels, the Tube's deep lines, and many pubs have no air conditioning. The pay-off is up to 16.5 hours of daylight in late June, with the sky still light past 9 p.m. That's prime time for Hyde Park picnics, open-top bus tours, Thames river cruises, and rooftop bars.
If you want warmth without the August school-holiday crush, aim for mid-June or early September. September still averages 19°C (66°F) with noticeably thinner crowds and cheaper rooms — one of the best value windows on the calendar. For travellers comparing European summer city breaks, see our guide to Barcelona in July for a warmer, beach-adjacent alternative.
The Cheapest Time to Visit London
January and February are the cheapest months by a wide margin. After New Year, demand collapses and mid-range hotels that charge £200+ in summer drop to £90–£140 a night. Flights from North America and Europe are also at their annual low. The trade-off is real: daytime highs hover around 8°C (46°F), it's dark by 4:30 p.m. in early January, and outdoor sightseeing is brisk.
The upside beyond price is that London's biggest draws are indoors and free. The British Museum, National Gallery, Tate Modern, the Natural History Museum, and the V&A all charge no admission, so a cold-weather trip can be packed and cheap. The post-Christmas January sales also make Oxford Street and Westfield genuinely worth the trip for shoppers. November and early December (before the holiday spike) are the next-cheapest windows. If winter city breaks appeal to you, compare the festive atmosphere in Paris in December.
The Best Time to Avoid Crowds
The quietest months are mid-January through mid-March and early-to-mid November. Major attractions like the Tower of London, Westminster Abbey, and the London Eye have short or no queues, and you can often walk up to West End theatre shows at a discount via the TKTS booth in Leicester Square.
Peak congestion hits in July and August (international tourists plus UK school holidays) and again from late November through New Year, when Christmas shoppers, markets, and Winter Wonderland in Hyde Park pack the centre. If you visit in those periods, book timed-entry tickets in advance and start sightseeing before 10 a.m. to beat the worst of it.
Month-by-Month Events and Festivals
- January: New Year's Day Parade; post-holiday sales; Chinese New Year celebrations in Chinatown (late Jan or Feb, depending on the lunar calendar).
- April: The London Marathon draws 50,000+ runners and big street crowds along the Thames route.
- May: The RHS Chelsea Flower Show (late May) is a world-famous gardening event — book early.
- June: Trooping the Colour marks the King's official birthday; Wimbledon qualifying begins late in the month.
- July: Wimbledon's main draw runs into early July; the BBC Proms classical season opens at the Royal Albert Hall.
- August: Notting Hill Carnival (August bank holiday weekend) is Europe's largest street festival, with over a million attendees.
- November: Bonfire Night (Nov 5) brings fireworks; Christmas lights switch on along Oxford and Regent Streets mid-month.
- December: Winter Wonderland, Christmas markets, ice rinks at Somerset House and the Natural History Museum, and New Year's Eve fireworks over the Thames (ticketed).
How Many Days Do You Need in London?
Plan for 4 to 5 full days to cover the essentials without rushing: one day for Westminster and the South Bank, one for the City and Tower of London, one for museums in South Kensington, one for markets and neighbourhoods like Camden, Notting Hill, or Shoreditch, and a flexible day for day trips. Popular nearby excursions include Windsor Castle (1 hour by train), Oxford or Cambridge (1 hour), and Bath or Stonehenge (1.5–2 hours).
If you're string together several European destinations, our seasonal travel guides can help you sequence the trip — for example, pairing a London stop with a city-comparison read like Lisbon vs Porto or planning shoulder-season timing the same way we break it down in Best Time to Visit Japan.
What to Pack for London by Season
Spring (Mar–May): Layers, a light waterproof jacket, and an umbrella. Temperatures swing between morning chill and mild afternoons.
Summer (Jun–Aug): Light clothing plus one warm layer for cool evenings, comfortable walking shoes, and sunscreen. A refillable water bottle helps on hot Tube journeys.
Autumn (Sep–Nov): Warmer layers, a proper rain jacket (October is the wettest month), and waterproof footwear.
Winter (Dec–Feb): A warm coat, hat, gloves, and a scarf. It rarely snows, but damp cold cuts deep, and daylight is short — front-load outdoor plans before 4 p.m.
Bottom Line: When Should You Go?
For the best all-round experience, book May or September — mild weather, long days, manageable crowds, and mid-tier prices. Choose July for the warmest, brightest holiday if you don't mind crowds and higher costs. Go in January or February for the cheapest trip, leaning on London's free world-class museums to stay busy. And visit in December only if the festive markets and lights are the whole point, because you'll pay a premium for them.
Frequently Asked Questions
What is the rainiest month in London?
October is the wettest month, averaging about 69mm of rain, followed by November and December at roughly 55–59mm. However, rainfall is fairly even year-round and tends to be light drizzle rather than heavy storms. Frequent grey skies — not heavy volume — drive London's rainy reputation. London actually receives less annual rain (~600mm) than Rome, Miami, or New York.
Is London expensive to visit?
London is one of Europe's pricier capitals, but cost varies sharply by season. A mid-range hotel runs £180–£250 a night in summer versus £90–£140 in January–February. Budget travellers can offset this with free museums, an Oyster/contactless travel card (daily fares are capped automatically), and pre-theatre or lunch menu deals. Expect to spend £100–£180 per person per day mid-range, excluding accommodation.
What is the warmest month in London?
July is the warmest month, with an average daytime high of 23°C (73°F) and occasional heatwave days exceeding 30°C (86°F). August is a close second at 22°C (72°F). Keep in mind that many older hotels, pubs, and parts of the London Underground have no air conditioning, so heatwaves can feel intense indoors and on the Tube.
When is the cheapest time to fly to and stay in London?
January and February offer the lowest combined airfare and hotel prices, often 40–50% below the summer peak. Early November and the first week of December (before holiday demand spikes) are the next-best value windows. Avoid Christmas week and New Year, when both flights and hotels surge.
Is London worth visiting in winter?
Yes. Winter is cold (around 8°C/46°F) with short days, but it's the cheapest season and the city's headline attractions — the British Museum, National Gallery, Tate Modern, and more — are indoors and free. December adds Christmas markets, Winter Wonderland, ice rinks, and festive lights, though prices climb. For a low-cost, crowd-free trip focused on museums and theatre, January–February is ideal.
