It's a long-standing joke that Londoners—and the English in general—chat obsessively about the weather. The London drizzle generates a fatalism that kicks off any conversation with a long-suffering nod to the heavens. Winter is usually dreary, cold, and wet (with occasional snow), spring is colorful and fair, June to August can be anything from a total washout to a long, hot summer and anything in between, while autumn can be "Indian-summer" warm, cool, or mild—or all three. Come prepared for anything—layers and a brolly are your best friends. One thing is sure: it's virtually impossible to forecast London weather, but you can be fairly certain that it will not be what you expect.
