London in October feels distinctly autumnal: days are cool rather than bitterly cold, rain is possible throughout the month, and daylight becomes noticeably shorter as November approaches. For most visitors, the best strategy is simple—pack layers, bring a waterproof outer layer, wear comfortable walking shoes, and plan your longest outdoor sightseeing for earlier in the day.
Quick Answer
London weather in October is usually cool and changeable. Met Office 1991–2020 averages for Heathrow show an average daytime maximum of about 16°C (61°F), an average minimum near 9°C (48°F), and roughly 65 mm (2.6 inches) of rain during the month. Layers, waterproof clothing and comfortable shoes are the safest choices.
Key Takeaways
- Typical October daytime highs are around 16°C (61°F), while average nighttime lows are about 9°C (48°F).
- Heathrow’s 1991–2020 climate normal is about 65 mm (2.6 inches) of October rainfall, with roughly 11 days recording at least 1 mm.
- Expect changeable weather rather than assuming every rainy day will be a washout.
- Daylight drops sharply through October, so outdoor sightseeing is easier earlier in the day, especially late in the month.
- In 2026, British Summer Time ends on October 25, when UK clocks go back one hour.
- Pack layers, a waterproof jacket or raincoat, and comfortable water-resistant walking shoes.
London October Weather at a Glance
| Average October maximum | 15.81°C (about 61°F) |
| Average October minimum | 8.78°C (about 48°F) |
| Average October rainfall | 65.07 mm (about 2.6 inches) |
| Days with at least 1 mm of rain | 10.8 days |
| Average wind speed | 7.13 knots, about 13 km/h (8 mph) |
Note: These are long-term 1991–2020 climate averages from the Met Office’s Heathrow station, not a forecast for a particular trip. Conditions in central London and individual Octobers can be warmer, colder, wetter or drier.
Average Temperature in London in October
October in London is generally cool and mild rather than wintry. According to the Met Office’s 1991–2020 Heathrow climate averages, the average October maximum is 15.81°C (about 61°F), while the average minimum is 8.78°C (about 48°F).
That makes layering more useful than relying on one heavy coat. A mild afternoon may be comfortable in a sweater and light jacket, while the same outfit can feel too light after sunset or when wind and rain arrive.
Temperatures also tend to decline as the month progresses. Early October can still produce relatively mild afternoons, while late October more often feels firmly autumnal, particularly in the morning and evening. A single monthly average therefore cannot tell you exactly what your trip will feel like.
Early October vs. Late October
If your trip falls in the first week or two of October, you generally have more daylight and a better chance of milder afternoons. By the final week, evenings arrive much earlier and cooler conditions become more noticeable. This matters when planning long park walks, river cruises, outdoor viewpoints or attractions with outdoor sections.
Check the current London forecast shortly before departure and again each morning. Climate averages are useful for packing, but a short-range forecast is more useful for deciding what to wear on a particular day.
Typical Rainfall in London in October
Rain should be part of your October packing plan, but the statistics do not mean that it rains continuously. The Met Office’s Heathrow climate normal records about 65.07 mm (2.6 inches) of rainfall during October and 10.8 days with at least 1 mm of rain.
A “rain day” in this statistic simply means that at least 1 mm of precipitation was measured during that day. It does not mean rain necessarily continued from morning to night. London can see brief showers, drizzle, longer wet spells and occasional heavier rain, so the practical approach is to stay prepared rather than assume a rainy forecast will ruin an entire day.
A compact umbrella can be useful when winds are light, while a waterproof jacket with a hood is often easier when you are walking through crowded streets or getting on and off public transport.
Pro Tip: Keep one flexible indoor attraction in your daily plan. If a wet spell arrives, you can move a museum, gallery, market or café visit forward and return to outdoor sightseeing when conditions improve.
Wind and Humidity in London in October
October can feel breezier as autumn develops. The Met Office’s Heathrow 1991–2020 normal gives an October mean wind speed of 7.13 knots, or roughly 13 km/h (8 mph). Actual winds can, of course, be much lighter or stronger on an individual day.
Wind also changes how cool the weather feels. Open spaces, bridges, parks and walks beside the Thames may feel colder than sheltered streets, especially after sunset or when your clothes are damp.
A single monthly humidity percentage is less useful for travelers because relative humidity changes considerably between mornings, afternoons, dry periods and rainy weather. Rather than planning around an unsupported fixed figure, prepare for the practical effect: after rain, conditions can feel damp and cool, so breathable layers and a water-resistant outer shell are useful.
Daylight Hours in London in October
October loses daylight quickly. At the start of the month, London still has more than 11 hours of daylight. By the end of October, daylight has dropped to under 10 hours, which noticeably shortens the time available for outdoor sightseeing.
The change feels particularly sharp late in the month because British Summer Time ends. According to GOV.UK, the clocks go back one hour on the last Sunday in October. In 2026, that happens on Sunday, October 25, when the UK returns from BST to Greenwich Mean Time.
As a result, evening darkness arrives much earlier during the final week of October. Parks, viewpoints, outdoor photography and long walking routes are usually easier to schedule for the morning or early afternoon, while museums, restaurants, theatre and other indoor activities work well later.
Note: If your trip crosses the October clock-change weekend, double-check attraction times, reservations and transportation schedules after your phone or watch changes from BST to GMT.
The biggest practical change during October is not just the cooler temperature—it is the steady loss of daylight, especially after the UK clock change late in the month.
How to Dress for London Weather in October
Dressing for London in October is mostly about flexibility. A long-sleeve top, shirt or light base layer works well underneath a sweater, fleece or cardigan. Add a light-to-medium jacket that can handle wind, and make the outer layer waterproof or water-resistant if rain is forecast.
You do not normally need to dress for deep winter, but a mild afternoon can turn into a chilly evening quickly. Layers let you remove clothing inside museums, shops, cafés and the Tube and put it back on when you return outdoors.
Useful October Packing List
- Waterproof or water-resistant jacket, preferably with a hood
- Compact umbrella if you like using one
- Two or three layerable tops
- Sweater, fleece or cardigan
- Comfortable trousers or jeans
- Comfortable water-resistant walking shoes or boots
- Extra socks in case your footwear becomes wet
- Light scarf for cool mornings, evenings and riverside walks
- Small day bag for an extra layer and rain gear
Comfortable footwear deserves particular attention because London trips often involve long periods of walking and standing. Waterproof shoes or boots are especially useful after rain, when pavements and park paths may remain wet even after the sky clears.
A scarf or light hat can add warmth without taking much room in a day bag. Heavy winter gloves and a thick insulated coat are usually unnecessary for average October conditions, although unusually cold weather is always possible.
Outdoor Activities in London in October
October can be a rewarding month for London’s parks and outdoor attractions. Hyde Park, Regent’s Park, Greenwich Park, Richmond Park and other green spaces gradually develop autumn color, although the timing and intensity of foliage vary with temperatures, rainfall and the individual trees.
Plan longer walks for dry or brighter periods rather than abandoning outdoor activities entirely because showers appear in the forecast. A morning park visit can work well before an afternoon museum, gallery or theatre booking.
The Thames is another good option when conditions are comfortable. Walking sections of the riverside gives you views of bridges, historic buildings and modern landmarks, but open riverfront areas can feel cooler when winds increase. Carrying an extra layer is useful even when the afternoon starts mild.
Cycling and guided walking tours are also possible in October. Check the forecast immediately before any activity that keeps you outside for several hours, particularly if strong wind or persistent rain is expected.
Indoor Activities in London in October
London has enough indoor attractions that poor weather does not need to derail a day. The British Museum, Tate Modern and other major museums and galleries provide hours of indoor sightseeing, making them easy alternatives when rain becomes inconvenient.
The West End is another strong October option. An evening theatre performance works particularly well late in the month when daylight ends earlier. Booking a show after a daytime walking route lets you use the brighter part of the day for outdoor sightseeing and move indoors after dark.
Cafés, covered markets and traditional pubs can also serve as useful breaks between attractions. Instead of building an itinerary that depends on perfect weather, mix indoor and outdoor stops so you can change their order if conditions shift.
Events and Festivals in London in October
October has a busy cultural calendar. Annual schedules can change, so travelers should always check current dates before booking, but several major events are already confirmed for 2026.
Black History Month runs throughout October in the UK, with exhibitions, talks, performances and other events across London. Halloween falls on October 31 and brings seasonal attractions and themed activities to venues around the city.
Film fans can attend the 70th BFI London Film Festival, which runs from October 7 to October 18, 2026. Screenings and festival activities take place at BFI Southbank and other venues.
Families should also be aware of the late-October school half-term period. Visit London’s 2026 calendar lists October half-term from October 26 to 30. Popular family attractions and museums can therefore feel busier during that week than during quieter parts of the month.
If a specific festival, theatre performance or seasonal attraction is important to your trip, reserve it first and build weather-dependent outdoor activities around that fixed booking.
Tips for Traveling to London in October
Start with climate averages when packing, but rely on the short-range forecast once your trip is close. London’s October weather is changeable enough that the actual forecast matters more than a monthly average when deciding whether a particular day needs an umbrella, warmer layer or waterproof shoes.
October is generally part of London’s autumn shoulder season rather than the peak summer period, but demand is not uniform throughout the month. Half-term, major festivals and popular weekend events can increase crowds at particular attractions, so booking important tickets in advance is sensible.
Public transportation makes it easy to change plans without spending long periods outdoors. Transport for London allows visitors to use contactless payment or an Oyster card for pay-as-you-go travel across its services. According to Transport for London, pay as you go is generally cheaper than buying paper single or return tickets, and daily or weekly capping can limit eligible travel costs.
If you use contactless, use the same physical card or the same phone/watch device when touching in and out. Switching between a bank card and the same card stored in a phone wallet can cause the system to treat them as different payment methods.
Build some flexibility into every day. A good October itinerary might pair a morning park or walking route with an afternoon museum and an evening theatre performance. If rain arrives earlier than expected, you can simply reverse the order.
Pro Tip: Two or three days before your trip, check the latest London forecast rather than making last-minute packing decisions from climate averages alone. Recheck each morning because the timing of showers and wind can change.
Enjoying London Weather in October
October offers a good balance for travelers who enjoy mild autumn weather, changing foliage and a strong cultural calendar. The main challenges are not extreme cold but changing conditions, regular chances of rain and rapidly shortening daylight.
Using Met Office climate normals as a packing guide gives you a realistic starting point: expect average daytime maxima close to 16°C (61°F), minima near 9°C (48°F), and around 65 mm of rainfall over the month. Then adjust your clothing and daily itinerary using the actual forecast.
Layers, water-resistant footwear and flexible sightseeing plans make most October conditions manageable. Schedule parks, river walks and outdoor landmarks while daylight is strongest, then use London’s museums, galleries, cafés, markets and theatres when the weather turns wet or evening arrives.
Before departure, check the latest forecast and any weather warnings directly from the Met Office. That gives you much more useful trip-specific information than relying on a monthly average alone.
