Sunrise and sunset in the most important cities of Saint Helena, Ascension and Tristan da Cunha

Duration of the sunset

The distance from the equator and the path of the sun determines not only the time of sunrise and sunset. The farther a country is from the equator, the more oblique the sun's path is to the horizon, causing sunset to last for a different duration. Jamestown lies on the 16th degree of southern latitude and thus a good distance from the equator. While a sunset in the northern USA or central Europe can take almost an hour, in Saint Helena, it lasts only an average of 25 minutes. Saint Helena is so close to the equator that there is no noticeable difference even between June and December.
