Chapter 56.39 - Prognostication of Rain

[Full title: Natural Astrology (39) prognostication of rain]

721-22a. If (when the possibility of rains is considered) it is the advent of the rainy season, the Moon being in a ‘watery sign’ (jala-rāśi)^[1], in the kendra if it is the bright fortnight and is aspected by benefic planets, there would be heavy rains. On the other hand, if the aspection (of the Moon) is by malefic planets and if it is summer, there would only be a little rain.

722b. The same will occur also when Venus is characterised by the different things mentioned for the Moon.

723. If in the rainy season, the Moon occupies the seventh house from Venus and is aspected by benefic planets, or in the trikoṇa or 7th house from Saturn, there would be (immediate) rain.

724. Venus will produce immediate rain if it is near Mercury. If, however, the Sun occurs between the two, there would be no rain.

725. Venus in the five asterisms beginning with Maghā (i.e., Maghā, Pūrvaphalgunī, Uttaraphalgunī, Hasta and Citrā) will cause rain, if the three asterisms Svāti, Viśākhā and Anurādhā follow (i.e., in the regular motion of the planet). If otherwise (i.e., in the retrograde motion of the planet), there would be no rains.

726. Planets near the Sun cause rains when they are just before or behind the Sun (in their regular motion), but not in their retrograde motion.

727. Venus coursing on the left will bring about rains if it is moving south. There would be rains in the morning and in the evening as the Sun enters the asterism Ārdrā.

728. There would be increase in vegetation during the twilights (due to rains falling at these times) and there would be prosperity on all counts for people during nights. Light rains will then reduce prices and no rains will increase crops.

729. If there is a division in the rising of Ārdrā, there will, no doubt, be a calamity. If, however, the Moon, Jupiter or Venus is in a kendra, the calamity will not occur.

730. The Sun occupying the asterism Pūrvāṣāḍhā and surrounded by clouds, will cause noticeable rains on all days from Ārdrā to Mūla.

731-32a. If there had been rains on Revatī (Pauṣṇabha), there would be no rains for ten days. If Siṃha is divided, how can there be rains and if Karkaṭa is divided, how can there be no rains. If the rise of Kanyā is divided there would always be plenty of rains.

732b-33a. (Rains in) Uttarabhādrapada are indicative of vegetation in the beginning and Revatī of vegetation in the end. Rains in Bharaṇī are indicative of vegetation throughout, while Aśvinī is indicative of destruction of all vegetation.

733b-34a. When Venus is in the 7th sign ahead of Jupiter, there would be heavy rains, especially if the rainy season is at its height.

734b-35a. If a halo (pariveṣa) occurs around the Moon, extending to seven asterisms (from it), there would be rains, heavily interspersed with lightning and accompanied by the croaking of frogs.

735b-36a. If the clouds in the centre of the sky are inclined towards the west or towards the south, there would be rains shortly.

736b-37a. Cats pawing the ground, encrustations occurring on metal and children building bunds on the pathways are indicative of rains.

737b-38a. Moving rows of ants, profusion of glow-worms, serpents climbing up trees are indicative of (immediate rains).

738b-39a. The Sun and the Moon, at rising or setting, appearing dull or coloured like honey and if there be severe wind at that time, heavy showers would follow, immediately.
