Solar Altitude & Azimuth: Darwin, Australia

Direct answer

In Darwin the sun reaches its highest point of the year, 90.0°, at 12:30 ACST on 26 October, and its lowest noon altitude, 54.1°, on 21 June. On 21 June it is 23.7° high at 09:00 and 41.8° at 15:00 local time, bearing 57° and 318° from north. At solar noon on 21 June (12:48 ACST) the sun bears 0° (N) at 54.1°. On 21 December it is 35.8° high at 09:00 and 56.1° at 15:00. The tables below give altitude and azimuth for every daylight hour on the 21st of each month in Australia/Darwin clock time, calculated with NOAA's solar equations for the city-centre point.

Reading the Darwin angle tables

Altitude is the sun's height above the horizon; azimuth is its bearing clockwise from true north. Hours are local clock time, so rows shift by an hour across a daylight-saving change. On 21 June the sun stands 23.7° high at 09:00 (bearing 57° (ENE)) and 41.8° at 15:00 (318° (NW)); those are the angles to test winter overshadowing from neighbouring buildings. On 21 December the same hours give 35.8° and 56.1°.

How these angles were calculated

Harth applied NOAA's solar-position equations, with standard atmospheric refraction, to the GeoNames point -12.4611, 130.8418 and converted each hour with the Australia/Darwin time zone. The angles hold to within about a tenth of a degree across the city centre; a site several kilometres away, or one with a raised horizon, should be recalculated from its own coordinates.
