Best Time to Visit

The best time to visit London is from April to June, when the weather is mild and the city is in full bloom. During spring, you can enjoy the colorful displays at Kew Gardens, picnic in Hyde Park surrounded by daffodils, and attend the Chelsea Flower Show in May.

Summer (July-September) is perfect for outdoor events like the BBC Proms at Royal Albert Hall, open-air theatre at Regent's Park, and enjoying rooftop bars with views of the city skyline.

Autumn (October-December) offers indoor activities like museum visits and cozy pub afternoons, plus the magical Christmas lights along Oxford Street and the Winter Wonderland in Hyde Park.

Winter (January-March) is ideal for ice skating at Somerset House, visiting indoor markets like Borough Market, and catching West End shows while escaping the chilly weather.
