Year distribution of sunrise and sunset times in San Martín Base, Antarctic Peninsula - 2026
The following graph shows sunrise and sunset times in San Martín Base, Antarctic Peninsula for every day of the year.
Daylight Dawn & dusk (civil twilight) Night Solar noon
Earliest and latest sunrise and sunset in San Martín Base
In San Martín Base, the earliest sunrise of 2026 is on November 26 at 1:38 am, while the latest sunrise is on June 6 at 1:24 pm. The earliest sunset is on June 6 at 1:29 pm, and the latest sunset is on January 15 at 1:15 am (after midnight).
San Martín Base gets 24h 00m more daylight on the longest day than on the shortest one (24h 00m versus 0h 00m). Averaged over the whole year, a day lasts 12h 15m.
San Martín Base Analemma
Due to Earth's tilted axis and slightly elliptical orbit, the Sun is never seen in the same position at noon in San Martín Base. Throughout the year, it slowly traces this figure-eight:
Move along the curve to read the Sun's altitude and azimuth for any day of the year in San Martín Base.
Over the year, the 12:00 Sun ranges from 3.1° below the horizon (around Jun 21) to 43.4° above it (around Dec 18) in San Martín Base. The smaller loop hangs at the bottom, the signature of a Southern Hemisphere analemma. For about 60 days around midwinter the whole figure sinks below the horizon — the Sun does not rise at noon at all. Notice the whole figure leans east of the meridian: over San Martín Base the Sun reaches its highest point between 13:11 and 13:42 depending on the time of year, but never at 12:00.
Detailed Analemma Chart
The technical chart below plots one dot per day, labels the first day of each month, marks the solstices, equinoxes, perihelion and aphelion, and draws the noon altitude of the equinoxes (90° minus your latitude) together with its ±23.4° seasonal limits.
Why does the figure look wider here than in the sky view above?
Both draw the same data, but with different conventions. The sky view uses the same scale on both axes, so it shows the analemma with its true proportions, as a camera would capture it: about 47° tall and only a few degrees wide. This chart, like most technical analemma diagrams, stretches each axis independently to fill the plot, expanding the narrow azimuth range several times so its day-to-day variation can actually be read. Also, azimuth is not sky distance: near the zenith, one degree of azimuth spans much less than one degree across the sky, which further widens the figure in this representation.
