This tool uses the classic Saptanadi system and principles of Vedic and Nadi astrology for monsoon rainfall prediction.
Saptanadi Nadis:
| Nadi Name | Nature | Weather Result |
|---|
| Vat | Windy | Windy weather |
| Ativat | Very cold | Cold |
| Dahan | Hot | Heat |
| Soumya | Pleasant | Rain producing |
| Neera | Watery | Rain producing |
| Jala | Watery | Rain producing |
| Amrita | Divine/Wet | Rain producing |
Key: More benefics (Venus, Moon, Jupiter, strong Mercury) in Amrita/Jala/Neera/Soumya → heavy rainfall. More malefics (Saturn, Sun, Mars, Rahu/Ketu) in rain Nadis → less rain.
Sun's entry into Aridra 'night' or 'late evening' is most auspicious for rainfall.
