Current Time in
London
London keeps Greenwich Mean Time (GMT) through the winter and shifts to British Summer Time (BST, GMT+1) from late March to late October, so the offset you plan around depends on the season. As the UK's capital and a global hub for finance, culture and long-haul connections, it draws business travellers, students and tourists from every continent, most of whom land jet-lagged after crossing several time zones.
Location Details
Daylight Status
It is currently daytime in London. The sun is up, making it a great time for outdoor activities or business calls.
When to Arrive & What Daylight to Expect
London sits at roughly 51.5 degrees north, so its days swing dramatically with the seasons. Around the June solstice you get close to 16.5 hours of daylight, with the sky still pale well past 9pm, while in late December daylight shrinks to under 8 hours and the sun sets before 4pm. If you can choose your landing, aim for a late-morning or early-afternoon arrival: that gives you a long stretch of natural daylight to anchor your body clock before a local bedtime, which is far kinder to your circadian rhythm than touching down after dark in the depths of winter.
Jet Lag Arriving in London
How hard London hits depends on where you fly in from. These figures are calculated from current time-zone offsets, so they account for daylight saving wherever it applies. Eastbound arrivals should chase morning light; westbound arrivals should seek late-afternoon light and resist an early night.

Hong Kong → London route guide →Getting Into the City
Heathrow, west of the city, is the main long-haul gateway. The Elizabeth Line runs into central stations such as Paddington and Tottenham Court Road in roughly 35–45 minutes for a modest fare, while the faster Heathrow Express reaches Paddington in about 15 minutes at a premium. Gatwick, to the south, links to Victoria via the Gatwick Express in around 30 minutes. Stansted and Luton, used heavily by budget carriers, sit further out: the Stansted Express reaches Liverpool Street in about 50 minutes, and Luton connects by shuttle and train via Luton Airport Parkway. London City Airport, closest to the centre, joins the DLR for a quick ride into the financial district.
Your First 48 Hours in London
On the day you arrive in London, resist the pull of a long nap no matter how tired you feel. Get outside and walk a green space such as Hyde Park or the South Bank to soak up daylight, keep a water bottle handy because cabin air leaves you dehydrated, and if you must rest, limit it to 20 minutes before late afternoon. Push through to a local bedtime of around 10–11pm; eating dinner at the British hour of roughly 7–8pm will help nudge your internal clock onto London time.
On your first full day, try to wake near a normal local hour rather than at dawn. If you have flown east from the Americas, seek bright morning light to pull your clock earlier; if you have come west from Asia or Australia, favour afternoon light to hold it back. A brisk daylight walk along the Thames or through a royal park does double duty, and a single morning coffee is fine, but stop caffeine by early afternoon so it does not undermine that crucial first proper night's sleep.
Local Practicalities
Most London shops open between 9 and 10am and close around 6pm, with later hours on Thursdays and shorter Sunday trading. Londoners tend to eat dinner relatively late, commonly 7–8pm, and many kitchens stop serving by 10pm. The weather is famously changeable, so a packable waterproof layer is wise in any season. Contactless cards and phones work seamlessly on the Tube, buses and trains, so you rarely need cash. Bear in mind the long summer evenings and dark winter afternoons when planning sightseeing, and note that pubs often close earlier than visitors expect.
