You’ll find Londoners in a state of mild confusion every morning. Do you grab the denim jacket, or risk the wool coat? It’s a wardrobe tug-of-war.
By 8 AM, you might shiver waiting for the Tube. By 2 PM, you’ll be peeling off layers while eating a sandwich on a park bench, feeling the golden warmth on your face.
My advice? Wear layers like you’re a human parfait. A light jumper under a jacket is your best friend this month.
The Temperature Rollercoaster
Let’s talk numbers, but in a friendly way. The average high in early September still hits a lovely 20°C (68°F). That’s “sitting in Regent’s Park with a good book” weather.
By the end of the month, the thermometer starts to dip. You’ll see more 15°C (59°F) afternoons, which is “stopping for a hot chocolate at the café on the corner” weather.
Don’t let the lower numbers scare you. These are the perfect temperatures for walking across the South Bank without breaking a sweat.
