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.
