When to Go

The heaviest tourist season runs mid-April through mid-September, with another peak around Christmas—though the tide never really ebbs. Late spring is the time to see the countryside and the royal parks and gardens at their freshest; fall brings autumnal beauty and fewer people. Summer gives the best chance of good weather, although the crowds are most intense. Winter can be dismal—the sun sets at 4 and it's pitch dark by 5—but all the theaters, concerts, and exhibitions go full speed ahead, and festive Christmas lights bring a touch of magic to the busy streets.
