* The Sun's Path: The sun's path across the sky in the Southern Hemisphere is opposite to that in the Northern Hemisphere. It rises in the east, arcs across the northern sky, and sets in the west.
* Southern Exposure: Because the sun spends most of the day in the northern sky, structures facing south will receive the most direct sunlight throughout the day. This is why in the Southern Hemisphere, "south-facing" is considered a desirable orientation for homes.
Think of it like this: Imagine the sun is a giant spotlight. If you stand facing south, the spotlight will be shining directly on you. If you turn to face north, you'll be mostly in the shadow of the light.
