While London is a great place to visit any time of the year, December is especially festive—as long as you can stand the cold.

London can be chilly and damp in December, but visitors will be delighted by the city's elaborate holiday displays. One of the best highlights in December is the Hyde Park Winter Wonderland (November to January). Get a big fat festive fix at this annual event in Hyde Park, which gets bigger and better each year. Expect food stalls, authentic beer halls, fairground rides, Santa's grottos, and free-flowing mulled wine. 

Annual Christmas events include carol singing, grottos, fairs, pantomimes and colorful lights. Christmas Day is December 25. Boxing Day is the first weekday after Christmas Day (December 26 or 27).

What to Pack

Like most of Europe in the winter, pack warm sweaters, long-sleeved T-shirts, pants, and a coat. On warmer days, or for formal outings, a dress with tights can be warm enough for women.

While it rarely snows in London in December, temperatures are cold enough to warrant packing gloves, a scarf, and sturdy boots or other waterproof shoes. Of course, it is London, which means an umbrella should be in your suitcase year-round!

December Events in London

  • London Christmas LightsFrom early November to early January, the annual Christmas light switch on is one of London's biggest festive events. The Oxford Street lights draw the biggest crowds as a celebrity usually flicks the switch. There are separate events for Regent Street, Covent Garden, Harrods and more. 
  • Trafalgar Square Christmas Tree Lighting Ceremony: This festive event is held the first Thursday in December. London is gifted a huge Christmas tree from Norway each year as a thank you for the country's services during WWII. The ceremony is usually accompanied by carol singing from the choir at the St-Martins-in-the-Fields church. 
  • The Great Christmas Pudding Race: Held in early December, this charity event that sees contestants complete a zany obstacle course while balancing a Christmas pudding on a plate. All while dressed as Santas, reindeer or elves, of course. 
  • Spitalfields Winter Festival (mid-December): This music festival brings opera, folk, classical and contemporary performances to quirky venues in and around Spitalfields in east London. 
  • London International Horse Show (mid-December): This annual event at Olympia attracts over 80,000 people a year and is one of the country's biggest equestrian festivals. 
  • Wrap up warm, get your skates on and check out one of London's many ice rinks which set up shop at iconic venues including Somerset House, the Tower of London and the Natural History Museum. 
  • 'January' Sales (from December 26): Snap up a bargain in the 'January' sales, which technically start on Boxing Day. Harrods, John Lewis, and Liberty are always reliable options for post-Christmas bargains.
