When is the best time to fly to London?

From Buckingham Palace to the official Changing of the Guard and the famous Westminster Abbey, there is so much to explore and enjoy in London. Spring (March – May) is by far the best time to visit London. At this time, you get longer daylight periods and mild temperatures. Temperatures in the spring average 11 – 15 degrees Celsius with periods of rainfall. Central London does fill up during the Easter weekend, and most shops are closed on Easter. Try to plan your spring visit so that you avoid the Easter holiday. Summer is also an ideal time to visit and temperatures are around 18 – 30 degrees Celsius from June – August. With favourable temperatures, you can take advantage of the city’s rooftop bars, beer gardens and plush gardens. If you prefer mild temperatures and a non-crowded city, then travel during autumn from September – November. The temperatures will average 11 – 15 degrees Celsius. During this season, you can enjoy the Totally Thames Festival and the endless Halloween fun.
