Bob Hope once observed of London: "Sometimes the fog clears and you can actually see the rain." Well, the dense fogs are a thing of the past since the Clean Air Act of the 1950s and London is actually one of the driest parts of the British Isles. But in a country so famous for its changeable weather, waterproofs or an umbrella are essential to have to hand at all times of the year. Conditions are always moderate with no great extremes of heat or cold, but the changeability means that London's weather rarely stays the same for too long. Winters are fairly cold, sunless affairs with plenty of days with slate grey skies. On average every other day will see measurable precipitation. In central London this is usually as rain - most years see very little snow - but there's a a slightly greater chance as you move out into the suburbs. Spring is when the weather's at its most unpredictable: the "April showers" of English folklore are rooted in fact. But if you're prepared for a sudden downpour or cold snap, Spring can be a good time to visit: this is generally the driest time of year and the sunshine amounts are reasonable. Autumn is usually wetter and cloudier than spring. Summer can see spells of quite warm weather in London (which makes the Underground unbearable) and although the rainfall amounts are quite high it is because of thundery showers. Even some summer days can be cool, sunless and wet. With over 20,000,000 visitors a year, picking the right time to visit London also involves when to avoid the crowds as much as the weather. Summers, especially July and August, and the weeks before Christmas are the busiest tourist times. If you want to avoid the worst of the crowds but don't like it too cold, as a Londoner I can recommend late September into October as my favourite time of the year. But whenever you visit, remember to plan for that changeability.
