Visiting London in September: What to Pack, Weather, Events & Things to Do (2023)

Thanks for visiting my site! Google penalized my site and made it impossible to find, so I appreciate that you use another search engine and trust me to help me plan your trip.

Imagine a crisp fall day: leaves crunch under your feet, your hands are wrapped around a cuppa, and a scarf keeps the chill away. Meanwhile, a red bus trundles by and you pass one of London’s many iconic sights as you stroll toward the Tube station to start your day of sightseeing. Is there any place better than London in September?

I certainly don’t think so – it’s my favorite month in London! It’s the perfect time to stroll under the changing leaves and provides a great excuse to pull out your wellies (rain boots) and jumpers (sweaters). While I’m not British, and I don’t call Britain home, I think Britain does autumn better than basically anywhere.

September Sunrise & Sunset Times in London

The length of each day you have to spend in London directly affects how many activities you can fit into your itinerary. That’s why I’ve included a chart of sunrise and sunset times in London in September:

Daylight Hours~13.5 hours~12.75 hours~11.75 hours

As you can see, September is a pretty good time to visit London. You can still take advantage of the last sunny days and warm, dry weather to discover London’s amazing city. 

On a side note, if you’d like to experience a sunset or sunrise in London, I’ve got two guides with vantage points, plus the sunrise and sunset times by month and season. 

London September Weather & Temperature

London in September - Weather

September is a month of transition. Consequently, you can expect the London temperature in September to vary considerably from the first two weeks to the last two weeks of the month. 

In early September, London still experiences comfortable weather with temperatures hovering around 70°F to 64°F in the daytime. Mornings and evenings are a bit colder; temperatures tend to average in the mid-upper 50° F. 

In late September, things get colder, with temperatures falling to the low-mid 50s during the day and into the mid-upper 40s in the early mornings and evenings. 

The good news is that September is a dry month, so no rain showers will prevent you from exploring London on foot or force you to find indoor activities. 

What to Pack for London in September

Now let’s move on to planning what to pack for London in September. 

Considering you’ll be visiting in a transition month, it may be tricky to know what clothes to wear in London in September. My advice is that you bring layers, so split your suitcase into light clothes for indoors and mid-weight layers for if it’s cooler. 

  • Pack a jacket or windbreaker. It will be your loyal companion against those chilly mornings and evenings. 
  • Bring layers! A couple of sweaters or cardigans you can wear and shed to your comfort.
  • Throw in two pairs of jeans.
  • Pack a fancy outfit. Londoners are a bit more fashionable, and you might want to dress up to attend a restaurant or rooftop bar. 
  • Bring two t-shirts. If you’re very sensitive to the cold, I would pack a couple of long-sleeved shirts as well. 
  • Don’t forget your umbrella! The rain returns in earnest as autumn sets in across England.
  • Similarly, a good pair of rain boots is always a good idea during this time of year.

9 Great Events in London in September 2023

Things to do in london - Festivals

You have purchased your ticket and packed your suitcase; now it’s time to see all the fun events you can attend in London in September. 

BBC Proms (July 14 – September 9)

The BBC Proms is the world’s biggest and longest-running classical music festival. It’s been part of London’s cultural agenda since 1895 and has grown to become one of the top things to do in London in September. 

For eight weeks, the BBC Proms hosts a series of concerts. The most famous concert happens on the festival’s last day. Called The Last Night of the Proms, an orchestra performs popular classics and British patriotic pieces that Londoners love. 

While it may be hard to snag tickets for the last night, visitors can always find tickets for any other concerts. Most concerts take place in Royal Albert Hall, but the BBC also broadcasts them across the UK on big screens as part of Proms in the Park events.

Greenwich+Docklands International Festival (August 25 – September 10)

Things to do in London - Docklands

Every year, Greenwich+Docklands International Festival brings the performing arts closer to people with an extensive program of art installations, street theater, circus, dance acts, and music events. An eighteen-day festival, GDIF takes place across Royal Greenwich, Docklands, and Tower Hamlets. Visitors can see a repertoire of UK and international artists presenting the most diverse street art performances. 

They’re revealing the 2023 lineup in June. To indulge your curiosity, here’s what happened in 2021. A theater company presented the i-Puppets parade – giant eye robot puppets that stomp down the street. Artists also created an immersive installation called Borealis, inspired by the Northern Lights. Then Black Victorians, a dance company, delighted the audience with choreographies inspired by often-overlooked Black figures in pre-Windrush Britain.

Pub in the Park Chiswick (September 1-3)

Pub in the Park Chiswick is nothing but the UK’s biggest celebration of food and music. Hosted by English chefs Tom Kerridge and Matt Tebbutt, the festival brings top-notch chefs who concoct delicious recipes in cooking demonstrations. You’ll go home with plenty of tips to create delicious dishes. 

Not everything is about theory, though. These chefs also bring their award-winning pubs and restaurants to the event so you can satisfy the foodie in you. Plus, famous singers will be musicalizing the festival – McFly and Ronan Keating are on the list for 2023.

Open House London Festival (September 6-17)

If you have a soft spot for beautiful architecture, you must attend the Open House London Festival. This two-week celebration allows visitors to discover London’s architectural hidden gems for free – and the word hidden isn’t used lightly here.

Forget about the iconic buildings; this festival opens the doors (for free) of buildings that are not usually open to the public. They’re private homes, schools, hospitals, museums, and pretty much any building or structure that have a story to tell and beauty to share. 

Visitors can also attend a wide range of special events and guided tours throughout the two weeks. 

London Fashion Week (September 16-20) 

London is part of the “Big Four” in the fashion scene alongside Milan, Paris, and New York City. 

Simple mortals with no links to the fashion industry may not be able to experience London’s Fashion Week firsthand – either you need an invitation to attend, or you can apply for tickets and hope they select you. However, no one can stop you from standing outside fashion shows and peeping at fashionistas worldwide wearing their best outfits. 

Bring a notepad! You’ll find tons of trend inspiration for the coming season.

London Design Festival (September 16-24)

Since 2003, London has celebrated contemporary and historic design together at the London Design Festival. This annual festival has gained a huge reputation over the years and has become a truly international festival celebrating London’s international status as a design capital.

In 2023, they are bringing more than 200 exhibitors from all over the world. The exhibitions, installations, workshops, and panels will take place across the city in venues like the Victoria & Albert Museum (one of the major hubs), South Bank, and King’s Cross. 

Premier League Matches (All month)

Bring out your competitive side and attend a Premier League match. The atmosphere of a London football game is something worth experiencing: rowdy fans chanting to encourage players as they wave their team’s scarves and the deafening enthusiasm of a cry of goooaaal when a player scores. There’s nothing like it.

A little word of advice; if you’re a newbie, try to avoid attending derby games like Arsenal vs. Tottenham, where fans can get a bit spiky. You can check here for Premier League fixtures to see which game you can include in your itinerary. 

Totally Thames (TBD)

London wouldn’t have become the city it is today without the River Thames. So it makes sense to have Totally Thames, a festival devoted to celebrating the river’s existence. The month-long festival hosts numerous physical and digital events along and beneath the Thames, from mudlarking to river-inspired art installations. 

Visitors can also attend talks to learn more about London’s most famous river. There are also concerts and art exhibits. Check their webpage to learn more about the activities they’ve organized for the 2022 edition. 

Chelsea History Festival (TBD)

One of the youngest London festivals, the Chelsea History Festival brings interactive opportunities to explore the UK’s fascinating history. Every year, their staff brings world-class speakers, like Philippe Sands, one of the UK’s most prominent human rights barristers, to discuss specific periods of the country’s history in a didactic way. 

It takes place in Chelsea Physic Garden and hosts more than 70 physical and virtual events. There are book talks, immersive outdoor installations recreating historic scenarios, and child-friendly activities like pond dipping.
