September in London: typical highs around 20°C, lows around 11°C and about 8 rainy days.
London weather is famously indecisive: grey skies, passing showers and the occasional glorious week. Summers are pleasantly warm, winters damp and chilly, and a compact umbrella plus layers are the local uniform all year.
The list below assumes a 7-day trip, flying in and sleeping in a hotel.
