Sunset and sunrise times in Kumasi, Ghana

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 6.7°N buys you.

Summer and winter days differ by 46m here, more seasonal variation than almost anywhere else in Ghana we track.

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 11 minutes earlier than it did on the first, a shift of roughly 22 seconds a day.

Among 17 tracked Ghana cities, sunset comes latest here, separated from Ho by 8 minutes.

Being inside the tropics means two zenith passages a year, 7 April and 6 September, when the sun is straight up at solar noon rather than merely high. The next one is in 12 days.

Sunset lands at close to the same time all year — the annual spread in day length is only 47 minutes, compared with about 8.8 hours at London's latitude.

The times barely move this week: the longest day of the year falls on 21 June, 2 months ago, so day length is changing by under a minute a day. Sunset shifts just 7 minutes earlier over the next fortnight.
