Mar del Plata is located at 38.00°S, 57.55°W. Its latitude determines how dramatically daylight hours change through the year.
The city uses the America/Argentina/Buenos_Aires timezone (GMT-3). It does not observe Daylight Saving Time, so solar times shift gradually through the year without abrupt clock changes.
Solar noon — the moment the sun reaches its highest point in the sky — occurs when the sun crosses the local meridian. In Mar del Plata this falls around 12:49 in mid-summer and 12:40 in December, reflecting UTC offset and any DST adjustments.
