The short answer: the best time to visit London is late spring (May to early June) or September, for the most reliable weather and manageable crowds. For the lowest prices, come in January, February or November. For festive magic, December is unbeatable, if pricey. London is a year-round city, so the right month really depends on whether you are chasing sunshine, savings or sparkle.
London does not have a bad season, only different ones. Summer brings long days and festivals, winter brings Christmas magic and bargains, and the shoulder months balance decent weather with fewer crowds and better prices. This guide walks through the whole year, honestly, so you can pick the month that suits the trip you want.
London 4 dummies: the truth about the weather
- It is not as rainy as you think. London gets less annual rainfall than Rome or New York; the rain is just spread into frequent light showers. Pack a compact umbrella, not a raincoat obsession.
- Summer days are long. In June the sun is up past 9pm, giving you huge, light evenings. In December it is dark by 4pm, so plan indoor afternoons.
- Layers always win. The weather changes through the day in every season. A layer you can add or shed beats one heavy coat.
- Heat is rare but real. A few summer days top 30C, and the Tube is not air-conditioned on many lines, so carry water.
- Book early for peak and Christmas. July and the run-up to Christmas are the priciest and busiest; the earlier you book, the better the rate.
London month by month
The whole year, season by season, with the weather, the crowds, the prices and what is on.
Spring (March to May): the sweet spot begins
March
Mild and brightening, with daffodils in the parks and far fewer crowds than summer. Prices are still reasonable, making it a lovely, low-key time to explore before the peak arrives.
April
Spring proper: cherry blossom, the London Marathon, and Easter events, though expect the odd shower. Days lengthen and the city feels alive again. Prices begin to climb around Easter.
May
Arguably the finest month: warm but not hot, long light evenings, the Chelsea Flower Show and green, blooming parks. Crowds are manageable and the weather is at its most reliable. A top pick.
Summer (June to August): long days, big crowds
June
Long days, warm weather, Trooping the Colour, the start of Wimbledon and festival season. The city is at its liveliest, though the crowds and prices are rising towards peak.
July
The warmest month and the busiest, with Wimbledon, Pride and the British Summer Time concerts in Hyde Park. Wonderful energy, but book early, as this is the priciest and most crowded time.
August
Warm and busy with summer visitors, and home to the huge Notting Hill Carnival over the late-August bank holiday. Many Londoners are away, so parts of the city feel a touch quieter mid-month.
Autumn (September to November): the connoisseur's choice
September
Often the best value-for-weather month: still warm, noticeably fewer crowds, and prices easing as the school holidays end. London Fashion Week adds a buzz. A quietly perfect time to visit.
October
Cooler and crisper, with glorious autumn colour in the parks and the Frieze art fair. Half-term brings a brief spike, but it is otherwise a calm, affordable month with plenty on.
November
Cold, dark and the best value of the year, with Bonfire Night on the 5th and the Christmas lights switching on across the West End late in the month. Great deals if you do not mind the chill.
Winter (December to February): Christmas magic and bargains
December
The most atmospheric month: dazzling lights, Christmas markets, Winter Wonderland, ice rinks and the New Year's Eve fireworks. Magical, but the mid-month run-up to Christmas is busy and pricey. Book well ahead.
January
The quietest, coldest and cheapest month, and the time for the January sales. If bargains and empty museums appeal more than sunshine, this is your month, just pack warm layers.
February
Still cold but brightening, with Chinese New Year celebrations in Chinatown and Valentine's for couples. A calm, good-value month, with a brief half-term spike near the end.

What is the best time of year to visit London?
For the best balance of weather and crowds, late spring (May to early June) and September are ideal, with pleasant temperatures, long days and prices below the summer peak. December is the most magical for Christmas, while summer offers the warmest weather and the most events, at the highest prices.
What is the cheapest time to visit London?
January, February and November are the cheapest months, when hotel rates drop and the city is quietest. Avoid the school holidays and the run-up to Christmas for the best value, and book early whenever you go to lock in the lowest price.
What is the weather like in London?
Milder than its reputation. Summers are warm rather than hot, usually in the low twenties Celsius, and winters are cold but rarely freezing, around five to eight degrees. Rain comes in frequent light showers rather than downpours, so an umbrella and layers cover most days year-round.
Is December a good time to visit London?
Yes, for the festive atmosphere. December brings dazzling Christmas lights, markets, Winter Wonderland, ice rinks and the New Year's Eve fireworks, and the city looks magical. The trade-off is cold, dark afternoons and higher prices and crowds in the run-up to Christmas, so book well ahead.
What is the rainiest month in London?
Autumn and early winter, roughly October to January, are the wettest, though no month is dramatically rainier than another, as showers are spread across the year. Even in the driest months you should expect the odd shower, so always pack a compact umbrella.
