Best Time to Travel: March – May
Average Temps: Highs in the 50s– 60s
As with other popular European cities, London receives the majority of its tourism crowds in the summer, when sunshine finally becomes the norm in an often overcast city, as well as the holiday season. Throughout the year, the city receives nearly 20 million international visitors, making it the third-most-visited metropolis in the world.
Shoulder season may seem the best time to visit, but the fall brings more rain than the spring in Londontown. The ideal time to go is actually between March and May, long after the holiday crowds have left and well before the summer influx. Sunshine is also more common during the spring, so you can enjoy flower-filled sunny days.
There is plenty to see, as well, with the world-renowned RHS Chelsea Flower Show and the reopening of Parliament both taking place in May.
