A Basic Guide to Astro-Meteorology
Charts to Use
1. Solar Ingress Cast a chart for the ingress of the sun into each of the four cardinal signs, i.e. 00 deg of Aries, Cancer, Libra and Capricorn. This chart is set using the coordinates of your location but using GMT. This will give you the seasonal influences for the year ahead. From this chart we are able to see the temperature variations that will occur in this location.
2. Lunation charts i.e. the four phases of the moon each month - new, first 1/4, full and last 1/4. These give the weekly trends. This covers the moisture picture for the week that the chart is in effect.
3. Mercury ingress charts cover the air movement for the period of time that Mercury is in a particular sign. Time on this one may vary.
4. The sunrise chart is set for the personal location and may be read in conjunction with the other charts for conformation on conditions that they show.
5. The chart is then interpreted using the 4th house as the main significator followed by the first house. 50% of the overall prevailing conditions are described by the planets in the 4th house, their sign and the aspects they make to other planets, followed by the sign on the cusp and its' ruler. 25% is from the 1st house - using the same formula. With the remaining 25% from the remainder of the chart and in particular any planet in a close approaching aspect to the MC.
6. First, note the planets in the 4th and 1st Houses - make notes of all of the effects of these planets. These notes will be your 'forecast' against which you will compare and note the actual weather for a lunation period.
7. About half of the conditions of the forecast are described by the planets in the 4th house, the sign they are in and the aspects to other planets and sensitive points.
8. Include the Sign on the 4th House cusp as the next influence.
9. About one quarter of the information comes from the Planets in the 1st House, the Sign they are in and the aspects they make.
10. The ascendant is a secondary influence.
11. Look also at the planets, which rule the 1st and 4th houses and consider their signs and aspects.
12. Pay close attention to planets, which are conjunct angles. These are very important and may override much of the sign descriptions. If these angular planets make hard aspects that too needs to be noted.
Sun - warm, dry, calm unless in violent combination. Primary to consider more marked effect when mutuals also aspect Sun with Moon gives extreme weather conditions. Venus conjunction cloudy or rainy
Moon - chilly, wettest of all planets. The lunar ingress into the cardinal signs (especially Capricorn) has an intimate link to record rainfall, especially via Jupiter's angularity. Venus and the Moon tend to be positioned on or near the angles of the ingress chart in higher than normal rainfall. The Moon's task is that of a trigger.
Mercury - wind, cool to cold, tends to dryness. Mercury governs the wind and corresponds to high pressure of fair weather. Gentle breezes to hurricane-force winds can be found under Mercury's domain. Mercury to the conjunction of Saturn, Uranus, Neptune and Pluto before the storm event may denote the type of wind force that may eventually work out into the environment. Causes fall in air pressure. Mercury/Uranus sudden squalls or violent gusts, Mercury/Saturn steady increase in wind strength more rain when retrograde
Venus - Under Venus, we find a warm, moist influence tending to lower the barometer. Moderately warm temperatures and gentle showers are among Venus's trademarks. In winter, it tends to augment snowfall or freezing rain. Moisture, moderating influence, consistently wet. Venus/Mars combinations often refer to storms
Mars - acute, heat, extreme if combined with other violent planets. Warm and dry influence. Hot summers, droughts, and mild winters are but a few of its traits.
Jupiter - warm, pleasant breezes, under the right conditions can be a big wind, tends to dryness By itself, Jupiter is considered a fair weather influence, bringing temperate conditions and an invigorating atmosphere. Jupiter raises temperature
Saturn - cold, wet, long lasting, extended gloom, stubborn and determined Typically produces cold and damp conditions that can be further aggravated when other testimonies concur. Storms or low-pressure systems engendered under Saturn are more prolonged and widespread. Fall in temperature rainfall. Saturn asp Sun/Uranus gloomy cold weather
Uranus - cold, dry, record breaker, unexpected changes, reversals, unstable, lightning, squalls Cold, dry air masses resulting in winter freezes and summer cold fronts are attributed to the power of Uranus. High barometer and very high wind velocities can be found under its influence as well. Sudden windy rainy cold
Neptune - cool, wet, fog, mist, erosion in an earth sign, peculiar, freakish weather events, flooding Neptune's power lies in its ability to lower the barometer and provoke torrential downpours and flooding conditions. During colder seasons, warming trends and thaws are Neptune's delight. Dry and warm stormy
Pluto - cool, violent, extremes, severe and intense depending on other chart indications. Some believe Pluto's effect to be similar to that of Mars.
Aries - warm, hot, dry - a moveable sign and can bring in some wind.
Taurus - cool, wet, a moderating influence and can be steady, farmer's rain.
Gemini - tends to cold, dry, fair, clouds moving, open sky, fluctuations in temp.
Cancer - cooling off to cold, wet, chance of rain with downpours, short-term wet.
Leo - hot and dry; the most still sign; in winter, melting snow.
Virgo - cold, dry, on the cool side with winds; blustery.
Libra - cool, lower temps rather than heat, airy breezes, favours dry; pleasant.
Scorpio - extremes, really wet/dry or hot/cold, con/destructive; oppressive; this sign intensifies the action of the rest of the chart. Never fails to bring an extreme.
Sagittarius - warm, dry, clear and sunny; pleasant, Indian summer, Jan. or Feb. thaw
Capricorn - coldest, storms, low temps in winter; can add to heat in summer; can be severe and long, periods of wet, especially on 1st or 4th
Aquarius - cold, dry and crisp; lightning; very changeable; adds to storm charts.
Pisces - cool, wet, mild, seasonable; moderates indications, second to Taurus
The traditional astrological aspects-the conjunction, sextile, square, trine, and opposition-and parallel of declination are important keys in determining weather patterns. The conjunction and parallel of declination can fall into either category, depending on the planets involved. Even Venus and Jupiter, can produce severe weather when ill aspected, as is the case when they are coupled with Neptune, for example.
Conjunctions can work either way and are considered the most powerful aspect of all. In season, the Sun-Mercury conjunctions often coincide with the formation of tropical storm systems and hurricanes.
Squares and oppositions can produce plenty of trouble or difficulty, especially aspects between Mars, Saturn, Uranus and Neptune. The square and opposition are considered to be storm breeders. Squares and oppositions between Mars and Saturn or Mars and Uranus can engender some very energetic storm systems.
Trines can offer a flow to the energies. The trine and sextile induce fair weather.
The descriptions of each planet must be blended with weather patterns in mind. For example, Mars usually indicates hot weather. In conjunction with Saturn (cold, wet, extended gloom) there is likely to be a meeting of two weather fronts creating the potential for thunderstorms.
Whole seasons are affected when the slower-moving planets from Jupiter on out form major aspects.
Astrometeorology (from Greek ἄστρον, astron, "constellation, star"; μετέωρος, metéōros, "high in the sky"; and -λογία, -logia) or meteorological astrology is a pseudoscience that attempts to forecast the weather using astrology.
Venus & Mercury
Mercury and Venus in the same sign and the same Navamsa and in combustion. Sun joining Mercury and Venus in the same sign and the same Navamsa it gives heavy rains. If the sign and Navamsa are watery signs, very heavy rains.
Astrology has been rejected by the scientific community as having no explanatory power for describing the universe. Scientific testing has found no evidence to support the premises or purported effects outlined in astrological traditions. Where astrology has made falsifiable predictions, it has been falsified.
Astrology is founded on understanding the positions of the stars, which seems like a scientific enough pursuit in itself. But is there any science to back up whether astrology impacts our personality and our lives? Here's the short Answer: No. None whatsoever.
