Predicting Weather By The Moon - Xavier University Libraries

Weather By The Moon
“O! swear not by the moon, the inconstant moon,
That monthly changes in her circled orb,
lest that thy love prove likewise variable.”
-Romeo and Juliet
There are some predictions one can make just by
watching the phases.
NEW MOON (DAY MOON)
New Moon Rise always occurs early morning, 6 -
7.30am
The New Moon and 1 st Quarter Moon are always over
the hemisphere experiencing summer. The New Moon is a
day Moon, meaning it is overhead during the daytime hours,
which tends to cause clear mornings and evenings, with any
cloudiness being mainly at midday(unless the Moon is in
Perigee , which would cause more cloud and possibly daytime
rain). Night skies are mainly clear and cool, even in
the summer. If the weather is unsettled and there is rain
about, the rain will be mostly in the period of early evening
until dawn.
The New Moon attracts the Moon to be in Perigee,
and the Perigee + New Moon combination often correlates
with earthquakes. There is maximum gravitational pull
at this time, due to the Sun and Moon being in line, and the
fact that the Moon is closest to the Earth for that month.
Any night tornadoes usually come at a New Moon.
