Daylight Civil twilight Nautical Astronomical Night

The earliest sunset of the year is at 17:19 on 3 November; the latest is 17:50 on 11 February. Those dates are not the solstices — the difference between clock time and solar time shifts them by a week or more.

Sunrise ranges from 05:13 on 3 November to 05:44 on 11 February.

Averaged across the year, a day here holds 12h 6m of daylight.

What makes sunsets in São Tomé different

Sitting on the eastern side of its time zone puts solar noon at 11:24, a full 36 minutes before twelve o'clock, and drags the whole day — sunrise, noon and sunset — along with it.

At 0.3°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.

The sun does not set in the same place twice: the December solstice puts it WSW, June swings it 47° round to WNW. Tonight, W.

Sunset drifts 21 seconds earlier each day this month — 10 minutes from the first of September to the last.

Twice a year the sun passes directly overhead here — on 21 March and 22 September — and vertical objects cast almost no shadow at solar noon.

At 0.3° the seasons barely touch the clock: 2 minutes separate midsummer from midwinter, against roughly 8.8 hours in London.

Sitting in 3 months of the shortest day (21 December) means the sun has almost stopped drifting — 12h 6m of daylight today, and only 4 minutes of movement in sunset over the next two weeks.

Planning a sunset photo in São Tomé

Arrive by 16:45. Golden hour opens at 17:00 and the sun is down by 17:27, so that leaves about fifteen minutes to find a position before the light is worth using.

Face west — the sun goes down at 269° on the compass today. That bearing moves through the year, so a composition that works this week may not in three months.

Do not pack up at sunset. Blue hour follows from 17:40 and runs to 17:48, the end of civil twilight and 20m after the sun disappears. That is the window where city lights balance against the sky.
