Sydney is surrounded by the Pacific Ocean to the east and the Blue Mountains to the west. The ocean has a moderating effect on the climate. It keeps temperatures relatively stable. The Blue Mountains block cold air from the south.
The mountains also force warm air to rise, cool, and condense, resulting in frequent fog and mist. This can reduce atmospheric pressure. The coastal location and rugged terrain combine to create a unique weather pattern.
