Yep. Seasons affect me. I eat less when I'm out and about more, when I do more fun things, and when I'm feeling too warm - all of those are things that happen in the summer. I also eat more when I'm less active, colder, etc.
One thing that helps me is to eat what I feel like eating. So in the summer it's easy, I want fruit, veggies, light foods that are cool in temperature (that helps with weight loss). In the winter I want heavier, warmer things like stews and warm sandwiches. So I shift what I make and buy - I get frozen/canned veggies for lower-calorie stews, and I'll make healthier versions of winter favorites. I find if I try to eat salads and fruit like I do in the summer, I get cranky and crave other, more wintery things.
So, for me, going with what I want to eat is a big help. And then I also move my exercise indoors and adjust as needed so I don't go crazy with no scenery (I listen to music, watch shows, read or listen to audiobooks, etc.).
Hope some of that helped.
