Example sentences:
- 外の方が家の中より暖かそうです。
- たいふうは西の方に去った。
ty!
In both cases, it is read as ホウ (the on'yomi).
One simple and helpful thing to realize is that the ほう reading means "direction" but the かた reading refers to either a person or way of doing something.
If you think about it, the first sentence is
外の方が家の中より暖かそうです。
"It seems warmer outside than inside the house."
たいふうは西の方に去った。
"The typhoon went to the West"
Both are directional.
