How would temperature extremes from summer to winter vary from ours if an Earth-like planet had an orbital period 4 times that of Earth?

I am imagining a world orbiting an F2 star, temp 7050K, at 2.87 AU, which I believe would be in the habitable zone and give an orbital period 4 times that of Earth. This is soft science fiction, so ...
