What effect does an aphelion have in each hemisphere?
It doesn't, really, much. The effect of apsis is completely swamped by the effect of axial tilt. I believe that southern hemisphere summers tend to be hotter, and southern hemisphere winters colder, than corresponding latitudes in the northern hemisphere due to the date of apsis (early January). But I don't know for certain that this is true.

It all depends on where you are, the northern hemisphere or the southern one.
