I really love summer when it's warm (so rarely in England)
& I love Winter when it's snowing. The problem with spring and autumn is that it is overcast all day, everyday and that awkward temperature when you don't know what to wear.
Winter because there is supposed to be snow, although its a bit rarer now than it used to be, and apart from that it is the coldest and I don't like warm weather. Winter>Autumn>Spring>Summer
