If you're planning anything outdoors in London, the good news is the city is drier than people think — less rainfall than Manchester, Cardiff or Glasgow, and a rain shadow effect from the Welsh hills keeps totals down. The bad news is unpredictability: Atlantic fronts, Continental heatwaves and North Sea easterlies all reach London, sometimes in the same week. August can be genuinely stifling once the urban heat island takes hold — central London routinely sits a couple of degrees above the surrounding countryside.
