Will Average Weather In London In September Ruin Your Holiday?
Of course, the weather is always a big topic of conversation in the United Kingdom. That’s because it is often terrible! But the London weather in September is still reasonably good.
And we are strong believers in the fact that you should never let the weather ruin your holiday! Luckily, whatever happens, London has a huge range of indoor attractions – so you will still have an epic time even if it rains.
Let’s check out what you can expect with the London weather in the fall.
What Is The Weather Like In London In September?
The weather in early September in London is still very much like the weather in August.
Expect pleasant temperatures into the low twenties (celsius) – that’s about 70 degrees Fahrenheit. As the month draws to a close however there is a distinct autumn vibe, and the daytime average temperature in London in September will drop to around 18 degrees celsius (maximum mid 60s Fahrenheit).
At this point, you will likely need a jacket in the evenings. Rainfall increases too from the August average and rain will fall on around 15 days in September.
However, note that only 8 of those days will see what is termed as “significant rainfall” – the other 7 days will likely receive just passing showers.
Packing Tips for Visiting London in September
If you are wondering what to pack for a trip to London in September, we’ve got you covered.
Here are the key items you will need to bring with you to London in September:
- A Raincoat: Don’t get caught in an unexpected shower – even going from an underground station to your hotel can get you soaked! The temperatures should be warm enough to get by with a very light waterproof jacket. A fold up hiking jacket should do, as long as you have a few jumpers for underneath if the weather gets cold.
- Jumpers: The mornings can be fresh and the evenings will start to see drops in temperature. If you want to make the most of the evenings exploring London outdoors you’ll need more than a tshirt.
- Comfortable shoes: Walking around London is the best way to see the city, but you will get tired! Make sure you have comfortable shoes for sightseeing. Ladies, stick your heels in your bag in the evenings unless you are travelling by taxi !
- Money Belt: Big city, be safe. Enough said.
What to Wear in London in September
The key to London – at any time of year – is layers. That’s especially true when thinking about how to dress for London in September.
That’s because you can move quickly from cool temperatures in the evenings outdoors to a crowded and warm bar. Or the sun can come out unexpectedly and you’ll be too hot on the bus. The changeable weather in the UK – and the difference between outdoor and indoor temperatures towards the end of the month – means you will need a flexible wardrobe.
Tshirts and Jumpers that can be layered up or down as needed are best. In the evenings, you may want to bring some dressy clothes if you plan to visit the opera or a fancy restaurant. And don’t forget that your shoes need to be comfortable and practical over stylish – especially for daytime sightseeing.
You’ll need to think a bit more about what to wear in London in late September. The autumn weather will be closing in and you’ll need a coat over your jumper, definitely in the evenings.

I’m Sebastian and I love exploring and writing about London. I’ve spent lots of time wandering around the city, finding cool places and learning all the best things to do. On my blog, LondonPass.info, I talk about all the awesome spots in London, from the famous ones everyone knows to secret places that are super special.
Of course, the weather is always a big topic of conversation in the United Kingdom. That’s because it is often unpredictable. It is certainly not “terrible” relative to many other places on the globe. Yeah, sure, terrible hot humidity in the summer if you want to look it in that way but rarely terrible in general even in the depths of winter relative to global standards. Only negative people will focus on the less good instead of the other way around.
Britain, England = terrible, hot, muggy, humidity in summer making 30C-40+C feel like 50’s C. Yeah, that’s terrible, agreed, for sure !
England and the UK are 2 totally separate countries when it comes to weather and the weather in England can be decent to superb in general, particularly between March / April through October or November. As was quoted on another site, there’s nothing like an English summer, which can be one of the best places to be out of anywhere when it’s really on point.
That great weather that happens in England can also occur at any time of year, including during winter, for given periods.
England summers can be and are hot, generally dry and sunny in eastern / central / southern England. The same weather can occur in the shoulder seasons as well, plus England generally has very pleasant spring and fall seasons, especially in the south and maintains enough sunshine throughout the winter in the year round warm south west England and English Riviera.
Yes, the summer humidity in England can be oppressive, especially for tourists who are not used to the generally very highly humid feeling summer heat that can occur in eastern, central, and southern England.
Plus, further to this, the generally dry climate of S E England / E England (East Anglia), can be really felt when you consider that these parts of England have areas classed as borderline semi -arid with less than 450mm / 17 inches of rainfall annually. Florida in the US had that same 17 inches within a 24 hour period again recently (June 2024), the same amount of rainfall that the drought prone / driest parts of England get in an entire year.
England’s climate and weather in general can be and is pretty great often at times (not always), in the warmer 9 months of the year.
Plus, London, for example, will have the climate of Barcelona in the near future.
