During the month of September, London is undergoing a transition. With summer technically lasting until the 21st, the city will begin to transform into an autumnal vibe. Londoners have just finished their summer holidays, and tourists are starting to decrease. The sense of excitement starts for the upcoming fall and events.
By the end of September, the warmth of the summer weather usually begins to subside, and temperatures begin to drop in October.
We do recommend to wear a good, warm jacket when it is cold outside. Do not be fooled by a beautiful sunny day before you go out; make sure you carry an umbrella with you. The beauty of the many attractions London has to offer will make your time in the city a memorable one.
September is a great month to visit as they balance the weather between warm and cold. You will not need thick clothes, but a jacket is necessary for evening and early morning. The tourism is still high but starts to go to low season as it goes into October.
There is a layer of crunchy leaves covering the streets and morning frost on the grass as the autumn season is round the corner. This means you need to know what to wear and pack in London during the fall.
Prepare clothes from your wardrobe that will keep you warm for layering. Also bring extra clothes that you can carry in a haversack.
Temperatures will start to drop in the evenings, and it might be cool in the mornings. Taking advantage of your evenings spent exploring London outdoors will require more than just a t-shirt if you want to make the most of them.
Make sure you don't get caught in an unexpected shower. Make sure you carry what you will need to put on immediately when needed. You should be able to get away with a very light waterproof jacket if the temperatures are warm enough. Should the weather turn cold, prepare a few jumpers for underneath.
