Golden hour in Hanoi in March

Hanoi lies at 21.03° N, in the tropics, where the sun climbs steeply and sets fast. Its longest measured day falls on Thu 18 June 2026 with 13h 25m of daylight, and its shortest on Sat 19 December 2026 with 10h 51m — a difference of 2h 34m between the two extremes.

Evening golden hour in Hanoi runs for roughly 32 minutes at the height of summer, 29 minutes around the March equinox and 33 minutes at midwinter. The warm window is actually widest in the colder months, which makes winter evenings unusually forgiving here.

The sun sets toward 296° WNW in late June and toward 245° WSW in late December, a shift of about 50° in where the last light lands — worth checking before committing to a west-facing viewpoint. In Hanoi, the sky reaches full darkness between evening and morning twilight year-round.
