London in September settles into an easy rhythm as summer crowds thin and the parks turn gold at the edges. Expect changeable weather, so pack a layer and something waterproof. The city rewards walking: cut through Hyde Park, wander the South Bank along the Thames, or lose an afternoon in the free galleries of the British Museum. Evenings suit a proper pub, a quiet corner and a decent pint.
