Sunrise & Sunset in Tucumán During September
September contains the spring equinox around the 22nd in Tucumán's Southern Hemisphere location. Day and night become nearly equal, and after the equinox, daylight overtakes darkness. The rate of daylight gain is at its fastest — up to three or four minutes per day near the equinox. Some regions begin daylight saving time, shifting sunset an hour later on the clock. The strengthening sun brings warmer afternoons and a noticeable lift in overall light quality.
Golden Hour & Twilight in September
During September, golden hour in Tucumán lasts approximately 48 minutes each morning and evening. The low sun angle during these periods produces warm, directional light prized by photographers and filmmakers. Civil twilight — the period when the sun is just below the horizon — adds extra usable light before sunrise and after sunset, extending the practical daylight window beyond the times shown in the table above.
Through September, days in Tucumán are lengthening by roughly 1.6 minutes per day, adding up to about 0h 45m over the course of the month.
