The official onset is declared by the Indian Meteorological Department (IMD) based on various meteorological parameters. This study aims to understand how the onset of the southwest monsoon over the Andaman–Nicobar Islands and Kerala can be forecasted using Medaniya Jyotisha (Mundane Astrology). In this study as per Geocentric concept among the nine classical planets, certain ones have a stronger influence on rainfall but I have considered only three planets — The Sun, Mercury and Venus, as they have the most significant correlation with Onset Southwest monsoon behavior. Mercury and Venus are inner planets, located closer to the Sun than Earth in our solar system. Their speed, position, conjunction (Yuti) with the Sun, and their nakshatra (constellation) positions, nakshatra Charan (pada) while rotation is crucial in determining onset Southwest monsoon patterns on Andaman-Nicobar and Kerala. (Note: In this context, “The Sun” represents Earth’s apparent motion in the geocentric system.) About this Monsoon pattern is written in Indian ancient scripture “Bhruhit Sanhita”. -------------------------------------------------------------------------------------------------------------------------------------------------------
