The United Kingdom's incomparable capital is a city for all seasons, but for some experiences, you have to visit during summer or winter. For instance, late July through late September is the only time when Buckingham Palace, the Queen's residence, opens for public tours. Compared to winters throughout much of North America, London's are mild, yet cold enough to support outdoor skating rinks at some of the city's most historic buildings, including the Tower of London. Winter is also the best season to take in theatrical productions.
Summer: Most Sun, Least Rain
London's weather is unpredictable, but visiting during summer offers the best chances for warm, sunny days with the least rainfall. From June through August, average highs are around 72 degrees Fahrenheit, lows in the mid-to-high 50s, with some rain on 16 to 20 days. Drawbacks include peak prices for airfares and hotel rooms, as well as the presence of throngs of other tourists.
Winter: Best Bargains
To take advantage of the cheapest airfare and hotel rates, Frommer's advises scheduling your visit from November 1 through mid-December, or December 25 through mid-March. November's average highs and lows are 54 and 45 degrees respectively, and temperatures from December through February range from highs of 48 degrees to lows of 41 degrees. You can expect precipitation on about 20 days of the month in winter, usually rain but sometimes snow.
