London In December: Weather, Daylight And What Is On

London in December is a month of trade-offs, and the trade is almost always the same one: the wettest, darkest stretch of the calendar is also the one where the city puts on its biggest show. Daytime highs sit around 8 to 10 C, the sun goes down before four in the afternoon, and that early darkness is exactly why the Christmas lights, the illuminated trails and the night bus tours land so well. Plan around the weather rather than against it and December becomes one of the best months to be in the city. This guide sets out the typical conditions, the daylight arithmetic, what to pack, which of our roster tours suit a wet evening, and what is actually on across the month.

What Is The Weather Like In London In December?

Expect daytime highs of about 8 to 10 C and overnight lows of 3 to 5 C, with roughly 50 to 60 mm of rain spread across the month. These are long-run averages, not a forecast: some Decembers deliver frost and clear skies, others deliver a week of grey drizzle. Treat them as a planning baseline, and check a live forecast a few days before you travel.

The honest summary is cold but rarely brutal. London's December temperatures are moderated by the city's own heat and by the Thames, so genuine sub-zero days are the exception rather than the rule. What catches visitors out is not the thermometer but the combination: 8 C feels considerably colder in a damp wind than the same number feels in dry continental air, and the rain more often arrives as drizzle or short showers than as downpours. An umbrella survives most days, but a hood or a waterproof jacket is less hassle on a crowded Oxford Street.

Rain is near-constant as a possibility rather than a certainty. The 50 to 60 mm monthly total is spread across many small events, which means the sensible strategy is not to plan around dry days but to plan activities that survive rain. London is unusually good at this: the roster's bus tours run in the rain with covered lower decks, the afternoon tea options are entirely indoors, and the light trails at Kew and the markets actually look better with wet reflective pavements under the installations.

One pattern worth knowing: the driest, brightest weather in a London December often comes in the first half of the month, before Atlantic systems stack up around the holidays. If your dates are flexible and you want the lights with the least rain risk, aim for the first two weeks of December, when the switch-ons have all happened and the school-holiday crowds have not yet arrived.

How Much Daylight Does London Get In December?

London gets its shortest days in December, with sunrise near 8am and sunset about 15:50 to 16:00 in mid month, leaving roughly eight hours of usable daylight. The winter solstice falls around 21 or 22 December, after which the evenings slowly start stretching back out. For visitors, the practical effect is that every plan after 4pm becomes a night plan.

This is the single most under-anticipated fact about a December trip to London. Visitors from lower latitudes are used to daylight lasting until six or later year-round; in London in December, the light is gone before you have finished your afternoon tea. The upside is generous: the Christmas lights, which in a longer-day city would be a minor curiosity, become the main event, and the city's whole evening economy, from illuminated trails to night bus tours, exists because of this darkness.

The scheduling consequence is real. Museums typically close between 5pm and 6pm, so a December sightseeing day effectively ends at dusk, not at closing time. The workable rhythm is: do indoor and daytime things from late morning, be outside in the golden hour around 15:00 to 16:00, then let the lights take over. The "Live Guide, 1.5-Hour Ride" lights bus tour is built exactly for this window; it runs 1.5 hours, is rated 4 from 5,439 reviews, and starts from $33 per person, with free cancellation per the listing. You can Check availability once you know your evening shape. Our bus tour comparison guide breaks down all the deck and route options.

The table's quiet message is that December days barely change length across the month, so there is no "better week" for daylight: every week gives you the same early-darkness deal, and every week gives you the lights in return.

What Is On In London Across December?

December stacks the city's biggest seasonal events into one month: Winter Wonderland runs 19 November to 3 January, Christmas at Kew runs selected dates 13 November to 3 January, the Somerset House rink runs 11 November to 10 January, and the Regent Street, Carnaby and Covent Garden lights are all lit by 12 November. By December itself, everything is running, and the calendar below is how to slot them into a visit.

The first thing to fix in your mind is that December is the peak of the season, not the start of it. Everything switches on in November, so a December visitor arrives with the full set already lit: the Regent Street "Spirit of Christmas" angels (lit from 5 November, illuminated 3pm to midnight daily), the Carnaby "Press Play on Christmas" installations from 4 November, and Covent Garden's "Theatre of Christmas" display of over 300,000 lights from 12 November. December is when you ride through all of it.

The trio above covers the three formats that suit December conditions best: an open-top lights bus for the dry evenings, a covered afternoon tea cruise for the wet ones, and a full-day studio trip with transport for the days you want to be indoors. The Warner Bros. Studio Tour is a year-round attraction rather than a Christmas product, but its Hogwarts in the Snow overlay runs 14 November 2026 to 17 January 2027 and is included in the standard timed ticket, per the official studio page. Note the studio is closed 25 and 26 December, and the listing does not state that the snow-season extras are included in the bus-inclusive booking, so read the live listing before you book.

Two December specifics deserve their own sentences. Christmas Day is the quietest day of the London year: no Tube, no buses, no national rail (last year's pattern, check TfL in December), most museums closed, but the Royal Parks stay open and free, and a small number of Christmas Day river cruises do sail. New Year's Eve is the loudest: the Mayor of London's fireworks return on Thursday 31 December 2026 from 8pm, with ticketed viewing areas and ticket release details still to be announced, per the official London.gov event page. Our New Year's Eve fireworks tickets guide covers the release pattern in full.

Which Tours Suit A Rainy December Day?

For wet evenings, the covered-deck lights buses and the indoor tea formats are the reliable picks: the "Lights Bus, Optional Afternoon Tea" runs from $34, the "1960s Routemaster Tea Bus" is entirely enclosed from $94, and the "Afternoon Tea Cruise, 1.5 Hours" keeps you under cover on the river from $53. Walking tours work too, with the right layers, and the mulled-wine walk builds its own warmth in.

The rain question is really a deck question. Every open-top lights tour has a covered lower deck, so rain downgrades the view rather than cancelling the trip, but the difference between watching Regent Street through a window and watching it from the top deck is the difference between a good evening and a great one. The pragmatic move is to book the bus with free cancellation, watch the forecast, and go on the driest evening of your stay. The "Open-Top Night Ride, Live Guide" is rated 4.5 from 2,049 reviews and runs 1 hour 30 minutes from $40, with free cancellation per the listing. The rest of the planning pages sit on Christmas In London.

For the days when the rain settles in properly, the tea formats are the answer. The "Markets Walk, Mulled Wine Included" tour is a clever hybrid: it is rated 5 from 72 reviews, runs 1 hour 30 minutes from $61, and the included mulled wine gives the walk a warm anchor between the light displays.

The 1960s Routemaster afternoon tea bus deserves its own mention as a rain plan. It is a year-round tour that runs through the Christmas season, not a Christmas product, but in December it passes the lit streets while you sit at a laid table with a pot of tea, which on a sodden afternoon is a genuinely superior way to see the lights. It is rated 4.4 from 2,121 reviews and runs 1 hour 25 minutes from $94; the card does not state cancellation terms, so check the listing before booking.

The "Afternoon Tea Cruise, 1.5 Hours" rounds out the wet-day set: a year-round cruise that runs through the Christmas season, rated 4.4 from 3,938 reviews from $53, with the listing noting it is likely to sell out. On a rainy December afternoon the river is at its most atmospheric, with the bridges lit and the water carrying the reflections.

What Should You Pack For London In December?

Pack in layers: a base layer, a warm mid layer and a waterproof outer shell cover most of December, with a hat and gloves for the evening light trails. Bring one smart-casual outfit for afternoon tea or a dinner cruise, shoes with real grip for wet pavements, and a bag that closes, since drizzle plus crowds is hard on open tote bags.

The layering advice is not generic travel filler; it maps directly onto how a December day in London actually unfolds. You will be hot on the Tube, cold on the embankment, warm in a tea room and cold again on a rink side, sometimes within the same two hours. The layer system lets you shed and re-add without carrying a full wardrobe. Skip the heavy ski parka: at 8 to 10 C it will have you sweating on every indoor stop, and it is miserable on a packed bus.

Footwear is the second decision. Wet stone and pavement, plus the possibility of ice on a cold morning, make grip more important than fashion. Whatever you wear to the Christmas at Kew trail, which covers roughly 3km of paths, should be something you are happy walking on for a couple of hours in the dark, possibly in drizzle. Our Kew tickets guide covers the trail layout and the gate-by-gate last entry times.

One packing note for the light trails and rinks specifically: gloves matter more than visitors expect, because Somerset House, Kew and the Hampton Court rink are all outdoor, evening-weighted experiences where you are standing still or holding a rail. The Hampton Court rink runs 20 November to 3 January excluding Christmas Day, and the Somerset House rink runs 11 November to 10 January with entry to the courtyard free for non-skaters, per the official venue pages.

How Does Getting Around Change In Late December?

The transport pattern shifts at the edges of the month: services run normally for most of December, finish early on Christmas Eve, shut down almost entirely on Christmas Day, and run a reduced Sunday-style service on Boxing Day. The 2026 festive timetable is not yet published, so treat this as last year's pattern and check TfL in December before making firm plans for 24 to 26 December.

Christmas Day is the day that surprises people. There is no Tube, no bus, no Elizabeth line, no DLR, no Overground and no national rail on 25 December, which is an annual UK-wide rule for the railways. What does run: taxis and private hire cars, National Express coaches, Santander Cycles, and the river, including the small number of Christmas Day cruises. If you are in the city on the 25th, plan around walking, cycling or the river, and read our Christmas Day openings and closures guide for the full picture.

Boxing Day, 26 December 2026, a Saturday, runs a reduced service: last year's pattern was Sunday-style frequencies on the Underground and buses, no Elizabeth line, no Night Tube, and only limited Overground routes. It is workable but slower, so build in more time than usual. Between 27 and 31 December the network returns to a broadly normal weekday service, with enhanced evening capacity on New Year's Eve itself, though the 2026 detail is not yet published.

Is December Actually A Good Time To Visit London?

Yes, and for a specific reason: December is the only month where the city's short daylight works in your favour, because the lights, trails and illuminated streets are the compensation for the darkness. The weather is manageable with layers, the crowds peak only in the 15 to 23 December window, and the first two weeks of December offer the full seasonal set with noticeably thinner queues.

The honest counter-arguments are three: it is dark by four, it rains on roughly half the days, and the peak fortnight is expensive and crowded. All three are true and none are fatal. The darkness is the point of the lights; the rain is answerable with the covered formats covered earlier in this guide; and the crowd problem is a scheduling problem, solved by coming in the first week of December or in the quiet 27 to 30 December window when the locals have left and the visitors have not yet arrived. Christmas In London exists as a site precisely because this month, planned well, outperforms every other month in the calendar.

For a fuller sense of the seasonal lineup beyond December's borders, our things to do at Christmas guide walks the whole list, and the walking tours guide details the on-foot options that suit the dry evenings.

If you take one planning rule from this page, take this: book your outdoor, weather-dependent plans for the evenings you can still shift, and hold a covered backup for each of them. The lights bus with free cancellation is the archetype of that approach, and the tea bus, the tea cruise and the studio day are its indoor counterparts.
