Sunset and sunrise times in Onitsha, Nigeria

Sitting on the western side of its time zone puts solar noon at 12:34, a full 35 minutes after twelve o'clock, and drags the whole day — sunrise, noon and sunset — along with it.

At 6.1°N the sun cuts through the twilight band at an angle, so darkness takes 21 minutes to arrive: 3 minutes shorter than today's 24-minute median.

Between the June and December solstices the length of the day swings by 42m here — among the narrowest of the 110 cities tracked in Nigeria.

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.

By the end of August the sun will be setting 10 minutes earlier than it did on the first, a shift of roughly 21 seconds a day.

On 5 April and 7 September the midday sun stands at the zenith, 155 days apart. Those are the only two days of the year with no noon shadow. The next one is in 13 days.

The longest and shortest days of the year differ by just 43 minutes here. In London the same gap is around 8.8 hours. That is about 12 times less seasonal variation.

Sitting 2 months ago of the longest day (21 June) means the sun has almost stopped drifting — 12h 16m of daylight today, and only 7 minutes of movement in sunset over the next two weeks.
