Sun Path: Perth, Australia

Direct answer

In Perth, the shortest day (21 June) has 10 h 03 min of daylight, from sunrise at 07:16 to sunset at 17:20 AWST, and the longest (22 December) has 14 h 15 min, from 05:07 to 19:22 AWST. The noon sun climbs from 34.6° to 81.5° above the horizon over the year. Sunrise moves between 63° (ENE) and 119° (ESE) and sunset between 241° (WSW) and 297° (WNW). The earliest sunrise is 05:03 on 4 December and the latest sunset is 19:26 on 8 January, which are not the solstice dates. Perth keeps AWST (UTC+8) all year, with no daylight saving. Times are local clock time from NOAA's solar equations for the city-centre GeoNames point at a sea-level horizon.

When does the sun rise and set in Perth each month?

Times are local clock time on the 21st of each month in 2026, including daylight saving where it applies. Bearings are clockwise from true north.

How the sun moves over Perth through the year

At -31.95° latitude the sunrise point swings 56° along the horizon over the year, from 63° (ENE) to 119° (ESE), and sunset moves between 241° (WSW) and 297° (WNW). On the shortest day the noon sun is 34.6° above the northern horizon; on 22 December it reaches 81.5°.

Solar noon falls at 12:01–12:30 on the clock through the year, because Perth sits 4.1° of longitude from its time zone's reference meridian and the equation of time shifts noon by up to 16 minutes. Use the clock times in the table, not 12:00, when you set up a sun study.

How these times were calculated

Harth computed each value with NOAA's solar-position equations for the GeoNames point -31.9522, 115.8614, using the standard 90.833° zenith for sunrise and sunset (refraction plus the sun's radius) and the Australia/Perth time zone. Hills, buildings and elevation move the sunrise and sunset you actually see by a few minutes; use surveyed site coordinates and a horizon survey for a specific building.
