The direction of the "point" of Earth's axis of spin does not change (at least not noticeably on human time scales - there is a 25 thousand year precession).
The orbit of the Earth round the Sun means that the north pole of this axis of spin is pointing towards the sun in Summer, away in Winter and sideways in Autumn and Spring.
It is June.

Magnetism leaves particles in molten metals lined up with north and south poles (magnetic poles, not the Earth's poles). Over time different layers of rock show that the N-S and S-N poles have switched, with S pointing in one direction and S pointing in a different direction depending on the age of the rock.

It is June.
