Since its 7:30 and the boy is riding his bike in the daytime, and he's wearing shorts and a short-sleeve shirt, I think it's summer.
I think it's autumn because there are pumpkins and the sun is rising at 7:15 A.M. and its still kind of dark and foggy.
I think it's winter because there is snow, the sun is very low at 4:30 P.M. and nobody is outside for 2 reasons: 1) It might too cold 2) It might be getting to dark, and, the leaves are gone and not on the trees anymore.
I think it is spring because the snow is melting and there are flowers growing, and the sun is out and it's out at 7:01 plus, the grass is green and has started to grow, also, the water is unfrozen now, this is in a swamp.
It looks cloudy outside, and other places in the photo don't really have a shadow, there's snow in the background, so it must be winter.
