Sunrise and sunset in the most important cities of Tonga

Sunrise and sunset by month (Nuku‘alofa)

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. And this causes a different duration that a sunset takes. Nuku‘alofa lies on the 21st degree of southern latitude and is therefore quite far away from the equator. While a sunset near the equator only lasts about 20 minutes, in Tonga this period averages 26 minutes. In June, it's about 25 minutes in Nuku‘alofa, while in December it's 27 minutes.
