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 19 seconds earlier each day this month — 10 minutes from the first of August to the last.

Today's earliest sunset in South Sudan happens here, 19 minutes earlier than in Winejok.

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. The next one is in 16 days.

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 2 months ago of the longest day (21 June) means the sun has almost stopped drifting — 12h 14m of daylight today, and only 6 minutes of movement in sunset over the next two weeks.
