Longest and shortest day in Buenos Aires
The longest day falls on 21 December 2026, in 4 months, with 14h 28m of daylight.
The shortest is 21 June 2026, 2 months ago, with 9h 49m.
Between them the day length swings by 4h 38m.
Daylight through 2026
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 56 minutes apart here — the sun is highest at 12:55 standard time. That gap comes from the time zone's width, not the latitude.
Sunset here is followed by about 26 minutes of usable light before civil twilight ends — almost exactly the 24-minute median across the cities tracked here.
Photographers get 50 minutes of golden light this evening, roughly 1.2× the 41 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 WNW.
Sunset drifts 43 seconds later each day this month — 22 minutes from the first of August to the last.
Planning a sunset photo in Buenos Aires
Arrive by 17:40. Golden hour opens at 17:55 and the sun is down by 18:30, so that leaves about fifteen minutes to find a position before the light is worth using.
Face west-northwest — the sun goes down at 282° on the compass today. That bearing moves through the year, so a composition that works this week may not in three months.
