Things to Do in London in September
Golden light, design and food festivals, and the crowds thinning
September is a connoisseur's month. The summer crowds recede, the light turns golden and warm afternoons often linger well into the month, yet the cultural calendar roars back to life. The London Design Festival spreads installations and events across the city, Open House London throws open the doors of hundreds of remarkable buildings you can't normally enter, and the food and film festivals return. Restaurants that were fully booked in July suddenly have tables, the parks glow with early autumn colour, and there is a settled, grown-up energy as the city gets back to work. Many locals quietly consider it the best month of all.
Weather
Mild and pleasant, with highs around 20°C early on, cooling gently through the month. An extra layer for the evenings.
Daylight
Noticeably shortening, with the autumn equinox around 22 September bringing roughly equal day and night; sunset slips to around 7pm.

Planning your September visit
- Some Open House buildings need advance booking or ballot entry — check the programme early.
- September is a great month for restaurant reservations that were impossible in summer.
- Bring a light jacket for the cooler evenings.
