September is the month of transition. It asks you a beautiful question every morning: “Do you want to enjoy the last whispers of summer, or embrace the first hints of autumn?”
When the forecast shows clear skies, say yes to the outdoors. Go to the top of the Sky Garden. Take a boat ride to Greenwich. Eat a fish and chips by the river.
When the forecast shows grey, don’t fight it. Light a candle, make a pot of tea, and watch an old movie. September weather gives you permission to slow down.
A Little Note on Humidity
London in September can feel a bit stuffy sometimes. The humidity is often around 70%, which means that 18°C can feel warmer than you expect.
Your hair might rebel a little. It’s okay. Everyone’s hair in London has a mind of its own in September. Just embrace the frizz—it’s the city’s way of giving you a natural, messy crown.
On muggier days, wear breathable fabrics. A crisp linen shirt or a cotton dress will keep you comfortable, while jeans might make you feel like a steamed dumpling.
