The live forecast above shows today’s conditions in London, but the city’s weather is famously changeable year-round. For most travellers, the best months are May to September, when days are longer and temperatures typically range from 15–25°C, though rain is never far away.
What is the best time to visit London?
Late spring (May–June) and early autumn (September) offer a good balance of mild weather, lighter crowds and lower accommodation rates than the peak summer school holidays. July and August are warmest but also busiest and most expensive. For a quieter trip, consider late April or October, when you’ll still get some pleasant days and cheaper deals.
What should I pack for a trip to London?
A waterproof jacket and layers are essential any month. In summer, pack light clothing plus a jumper for cooler evenings; in winter (December–February), a warm coat, scarf and gloves are needed. Comfortable walking shoes are a must, as you’ll likely cover a lot of ground. An umbrella is useful year-round, but not always reliable against London’s gusty showers.
Does it rain a lot in London?
London gets about 600mm of rain a year – less than many UK cities. Rain falls on roughly half of days, but showers are often light and short. A dry spell can last several days, especially in spring or summer.
