The sun positioned itself directly overhead in four Sri Lankan cities on August 27, 2026, an astronomical phenomenon that occurs twice annually as the sun crosses the equator.

Sri Lanka experienced a notable astronomical event on August 27, 2026, when the sun reached its zenith directly above four cities across the island nation. This occurrence, known as the sun passing through the zenith, is a natural phenomenon that takes place at specific latitudes twice each year as the sun's vertical rays traverse different parts of the Earth.

The zenith sun position is determined by the sun's declination relative to the observer's latitude. For locations between the Tropics of Cancer and Capricorn, this event occurs twice annually—once during the sun's northward journey and again during its southward journey across the equatorial plane. Sri Lanka's geographical position in the tropical region makes it experience this phenomenon regularly.

The timing of these events varies depending on each location's exact latitude. The four cities that experienced the zenith sun on this date represent different geographical points across Sri Lanka, highlighting the island's tropical characteristics and its position within the sun's seasonal path across the equator.
