Sunset and sunrise times in Port Harcourt, Nigeria

Clock noon and solar noon are 23 minutes apart here — the sun is highest at 12:23 standard time. That gap comes from the time zone's width, not the latitude.

From sunset to full civil darkness is 21 minutes here, against a 24-minute median elsewhere today. Latitude 4.8°N accounts for the 3-minute difference.

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

Over a year the sunset point slides 47° along the horizon, from WSW at the December solstice to WNW in June. Today it is W.

Sunset drifts 28 seconds earlier each day this month — 14 minutes from the first of September to the last.

Being inside the tropics means two zenith passages a year, 2 April and 11 September, when the sun is straight up at solar noon rather than merely high.

The longest and shortest days of the year differ by just 33 minutes here. In London the same gap is around 8.8 hours. That is about 16 times less seasonal variation.

The times barely move this week: the shortest day of the year falls on 21 December, in 3 months, so day length is changing by under a minute a day. Sunset shifts just 6 minutes earlier over the next fortnight.
