Visits to the capital's top attractions rose in 2010 but were still affected by bad weather, Visit London has revealed.
London welcomed 3.1% more visitors than in 2009 and 4.24 million tourists between July and September alone.
Visit London said the last quarter showed a mixed picture with a 2.3% rise on the year before but December saw a 7% drop as temperatures plummeted.
It is hoped April's royal wedding and other major events will boost figures for 2011.
Sally Chatterjee, Visit London's CEO, said: "It is very positive news for London that our attractions have seen a growth in visitor figures despite a challenging year.
"While the majority of the year experienced a steady increase in visitor numbers, external factors such as weather, air strikes and the volcanic ash disrupted the overall growth pattern."
The figures come from a sample of 34 attractions across the capital including the British Museum, the London Eye and St Paul's Cathedral.
