Ive already gained my winter weight and more over summer, fortunately I tend to wear loose clothes on top anyway, but my 28 inch waist jeans are getting tight and are a struggle to do up, maybe time to upgrade to 34 or 36s soon for more room
My summer gains are usually accidental, I travel and when I find a new place I go nuts for the food and drink and before I know it I'm fatter than when I arrived, winter comes and I gain on purpose
