Sunset and sunrise times in Juba, South Sudan

Light lingers for 21 minutes after sunset before civil twilight ends — 3 minutes shorter than the 24-minute median across tracked cities, which is what 4.9°N buys you.

The gap between the longest and shortest day of the year comes to 33m, one of the narrowest swings of any South Sudan city on the site.

Between solstices the sunset walks 47° across the horizon — WSW in midwinter, WNW in midsummer — which is why a fixed viewpoint works only part of the year. Today's bearing is W.

Sunset drifts 20 seconds earlier each day this month — 10 minutes from the first of October to the last.

Being inside the tropics means two zenith passages a year, 2 April and 10 September, when the sun is straight up at solar noon rather than merely high.

At 4.9° the seasons barely touch the clock: 34 minutes separate midsummer from midwinter, against roughly 8.8 hours in London.

Elevation matters at 518 m. The visible horizon drops 0.79°, pushing sunset 3.2 minutes later and sunrise the same amount earlier than a sea-level observer would see.

Sitting in 2 months of the shortest day (21 December) means the sun has almost stopped drifting — 12h 2m of daylight today, and only 5 minutes of movement in sunset over the next two weeks.
