Best Time to Visit London: Seasons, Weather & Tips - Travel Expert

Best time to visit London

The best time to visit London depends on your priorities: spring (April–June) and early autumn (September–October) offer the best balance of mild weather, manageable crowds, and lots of events. Summer (July–August) is busiest with warmest weather; winter (November–February) is quieter and cheaper but colder and darker.

Why choose each season

• Spring (April–June)

  • Pros: Mild temperatures (8–20°C / 46–68°F), blooming parks, long daylight, major events (Chelsea Flower Show, Easter events).
  • Cons: Can be changeable; occasional rain.

• Summer (July–August)

  • Pros: Warmest weather (15–25°C / 59–77°F), lots of festivals, extended daylight, best river/park activities.
  • Cons: Highest crowds and accommodation prices; popular attractions have long queues.

• Early autumn (September–October)

  • Pros: Shoulder-season benefits—still pleasant (10–20°C / 50–68°F), fewer tourists, cultural season starts (theatres, exhibitions).
  • Cons: Weather becomes more unpredictable later in October.

• Winter (November–February)

  • Pros: Lowest prices, Christmas markets and lights, fewer crowds at museums and attractions.
  • Cons: Cold (around 2–8°C / 36–46°F), shorter days, occasional snow but often rain.

Practical tips

• If you want best weather and fewer crowds: aim for late May–early June or September.
• For lowest costs: travel in January–February (after New Year) excluding school holidays.
• Book popular attractions and West End shows in advance for summer and Christmas periods.
• Pack: waterproof layer and comfortable shoes year-round; add warm layers for winter and a light jacket for spring/autumn.
• Transport: get an Oyster card or contactless payment for tube/bus; expect delays during strike action or maintenance—check Transport for London before travel.

Quick checklist for timing

• Families: school holidays (July–August) but expect crowds.
• Culture & theatre: September–April season opens in September.
• Events/markets: December for Christmas lights and markets; June for outdoor festivals.

Bottom line: For most visitors the sweet spot is late spring (May–June) or early autumn (September) — best mix of weather, fewer crowds, and good event options.
