The summer solstice occurs in the northern hemisphere when the sun is at the most acute angle above the horizon. It usually occurs on or about June 21.
Perth is at 32 degrees south and on the summer solstice the Sun's declination is 23½ degrees south. Therefore the Sun is 32-23½ degrees or 8½ degrees from the zenith, that is 81½ degrees above the horizon.
The Summer Solstice is the event that occurs when the Sun reaches its highest declination, or angle above the equator. In fact, the monoliths at Stonehenge in England were set up to tell astronomers 2000 years ago when the Summer Solstice had arrived.
On the Summer Solstice, June 21, the Sun is at about 23.5 degrees north. If you are at 50 degrees north, then at noon ("Local Apparent Noon", when the Sun reaches its highest point in the sky) on June 21, the Sun will be at an altitude of 66.5 degrees above the southern horizon.
In the Southern Hemisphere the summer solstice occurs when the sun is the farthest south.
