Daylight Civil twilight Nautical Astronomical Night

The earliest sunset of the year is at 17:49 on 12 June; the latest is 20:10 on 6 January. Those dates are not the solstices — the difference between clock time and solar time shifts them by a week or more.

Sunrise ranges from 05:33 on 5 December to 08:01 on 29 June.

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

What makes sunsets in Buenos Aires different

Clock noon and solar noon are 45 minutes apart here — the sun is highest at 12:44 standard time. That gap comes from the time zone's width, not the latitude.

Sunset here is followed by about 25 minutes of usable light before civil twilight ends — almost exactly the 24-minute median across the cities tracked here.

Photographers get 49 minutes of golden light this evening, roughly 1.2× the 40 minutes available at the equator on the same date.

Between solstices the sunset walks 58° 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 43 seconds later each day this month — 21 minutes from the first of September to the last.

Planning a sunset photo in Buenos Aires

Arrive by 18:04. Golden hour opens at 18:19 and the sun is down by 18:53, so that leaves about fifteen minutes to find a position before the light is worth using.

Face west — the sun goes down at 268° 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 19:08 and runs to 19:18, the end of civil twilight and 25m after the sun disappears. That is the window where city lights balance against the sky.
