What Determines Sunset Time?

Sunset time in Iguazu Falls is determined by the city's latitude, longitude, and the time of year. During summer, the Earth's axial tilt causes the sun to take a longer path across the sky, resulting in later sunsets. In winter, the opposite occurs — shorter days mean earlier sunsets. Near the equinoxes (March and September), sunset times change most rapidly, shifting by 2–3 minutes per day. At Iguazu Falls's latitude, the difference between the earliest and latest sunset can be several hours across the year. Our daily calculations use precise astronomical data to give you the exact sunset time accurate to the minute.
