Autumn Vibes Approaching, Climate in London for September

The change of weather starts with crispy leaves lining the streets, and morning frost begins to appear. The London weather in September starts getting a bit chilly as the day goes on.

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.
