Basic Guide to Astro-Meteorology
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.
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.
Mercury ingress charts cover the air movement for the period of
time that Mercury is in a particular sign. Time on this one may
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.
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
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
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.
Include the Sign on the 4th House cusp as the next influence.
About one quarter of the information comes from the Planets in the
1st House, the Sign they are in and the aspects they make.
The ascendant is a secondary influence.
Look also at the planets, which rule the 1st and 4th houses and
consider their signs and aspects.
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

- 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.
- 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

storm event may denote the type of wind force that may eventually
work out into the environment. Causes fall in air pressure. Mercury/Uranus

- 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

Warm and dry influence. Hot summers, droughts, and mild winters
are but a few of its traits.

influence, bringing temperate conditions and an invigorating atmosphere.

aggravated when other testimonies concur. Storms or low-pressure

as well. Sudden windy rainy cold

to lower the barometer and provoke torrential downpours and flooding

that of Mars.

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,
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.
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.
can offer a flow to the energies. The trine and sextile induce
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.
seasons are affected when the slower-moving planets from Jupiter
on out form major aspects.
