Sun path in Hong Kong

In summer the Sun rises north of east and climbs higher. In winter it rises south of east and stays lower.

Max Sun altitude today: 88.9°

Sky dome cross-section

Horizon (E–W)

Before you start

The Sun follows a different track across the sky each day of the year. Summer paths are higher and longer.

Key idea

Earth's 23.5° tilt changes the Sun's declination through the year, which changes rise direction, maximum height, and day length.

What you see

  • Sky dome cross-section with the Sun's daily arc
  • Optional Earth–Sun orbit inset
  • Maximum altitude readout for Hong Kong

Try this

  1. Compare June 21 vs December 21 arcs
  2. Toggle the orbit animation to connect season to position in orbit
  3. Note summer Sun rises north of east in HK

Why it matters in Hong Kong

Hong Kong's subtropical latitude means the noon Sun can pass slightly north of zenith in summer.

Common mistakes

  • Thinking the Sun always rises in the east exactly — only at equinoxes
