Weather By The Moon From above and looking down, it would look as if the Moon was on the opposite side of the Earth to the Sun. When we gaze up at the Full Moon and see the night sky beyond it, we are gazing into the far reaches of the universe, beyond the limit of our orbit around the Sun, into space we never as a planet enter. Full Moon is called a Night Moon, because that is the only time it is in our sky. When the Full Moon becomes a couple of days old, some may claim to be able to see it in the early morning, but although it is still quite full looking, it is no longer really a Full Moon. Over the Full Moon phase, cloud and rain, if about, will mainly appear during the day, clearing by evening and staying clear until sunrise the next day. If a barbecue is to be held, picking the full moon night of the month will usually guarantee clear weather. Two weeks have now passed since New Moon. The Moon, continuing on its relentless orbit, comes around the Earth on the far side to once again approach the Sun. A few days out from Full Moon, it has become Waning Gibbous. WANING GIBBOUS. The Moon’s appearance is now an exact mirror-image of the Waxing Crescent. From just before lunch until just before dinner is the likely period for cloud, whilst the skies 66

are more likely to be clearer from an hour or two before midnight until morning tea the next day. LAST QUARTER Through the Phases A week after being Full Moon, the Moon is overhead at Sunrise, and is called 3rd or Last Quarter. It now looks like a C in the Northern Hemisphere and a D in the southern hemisphere. A mirror-image of the 1 st Quarter, it is said now to be ‘on the wane’. Having risen progressively later during the night, it remains in the sky well after the Sun has come up. It is the Moon seen by daylight before lunch. Now, its position marks where Earth will be in space (on our orbit around the Sun) in three and a half hours time. At Last Quarter, one can typically expect any cloud or rain that is about, to be overhead in the afternoon and early evening, clearing somewhat by in the wee small hours of the following morning with skies staying reasonably clear until lunchtime the next day. Two or three days later, the cloudiness appears mainly in the evening through midnight. Sometime in the night the skies are more likely to clear and stay clear until late afternoon the next day. Now the Moon is known as Waning Creescent: 67

LAST QUARTER<br />

Through the Phases<br />

A week after being Full <strong>Moon</strong>, the <strong>Moon</strong> is overhead<br />

at Sunrise, and is called 3rd or Last Quarter. It now looks<br />

like a C in the Northern Hemisphere and a D in the southern<br />

hemisphere. A mirror-image of the 1 st Quarter, it is said<br />

now to be ‘on the wane’.<br />

Having risen progressively later during the night, it<br />

remains in the sky well after the Sun has come up. It is the<br />

<strong>Moon</strong> seen by daylight before lunch. Now, its position<br />

marks where Earth will be in space (on our orbit around<br />

the Sun) in three and a half hours time. At Last Quarter, one<br />

can typically expect any cloud or rain that is about, to be<br />

overhead in the afternoon and early evening, clearing somewhat<br />

by in the wee small hours of the following morning<br />

with skies staying reasonably clear until lunchtime the next<br />

day.<br />

Two or three days later, the cloudiness appears mainly<br />

in the evening through midnight. Sometime in the night the<br />

skies are more likely to clear and stay clear until late afternoon<br />

the next day. Now the <strong>Moon</strong> is known as Waning<br />

Creescent:<br />
