THE WEATHER FOR SYDNEY
This weather forecast uses
the effect of the moon and the tides, and the following
information is for the Sydney
Metropolitan Area only. Sydney has its own
Climatic Zone which is not
the same as the rest of the NSW coast.
My original analyses of the
moon phases and the weather of Sydney dates back
more than 20 years.
I read an article in a science journal written by two NZ
meteorologists who had proved
a moon - weather relationship for NZ.
An attempt to find something
similar for Australia failed.
My interest in sailing made
me realize that although a link was difficult
to prove in scientific terms,
it was an obvious fact.
If this system is followed
for a month or more it will be found to be more accurate than expected.
The possible explanation could
be the effect of some factor which is as yet unknown.
This method, using just the
moon and tide tables for the cost of a few dollars, will compare
very well with
traditional forecasts - which
are sometimes wrong - and are based on information costing millions of
dollars.
The analysis of other areas
could give more positive results.
This method can look well
into the future and its predictability has remained constant for at least
15
20 years.
This means that a particular
months chart could have been written 20 years ago.
The missing information in
these charts would be drought or wet periods, local knowledge, seasonal
variations,
the offshore sea temperature
and currents, cyclonic disturbances, sun spot activity etc.
The worlds weather also appears
to have cycles of calm and turbulence.
This is a simplified version
but will be better than a guess. This information is based
on about 20 years
of observations
No responsibility taken.
The chance of rain can also be viewed as the relative weather instability.
The best chance for a
fine day is before any moon phase day, at the new moon, and
a few days before the
full moon.
Although the chance of
rain just before the full moon is very low, the days could be overcast
and cooler.
The days before the 1st and
3rd quarter should be warmer than the days before the new moon or full
moon.
Heavy rain to the tropical
north dumps moisture into the rising tropical air which is carried by air
currents
down to the Sydney region.
This greatly increases the chance of rain.
Watch for weather fronts approaching
from Melbourne - Adelaide, and for cloud across central Australia
bringing
rain from the Indian Ocean.

The weather on a moon phase
day will give an indication of the weather to follow IF
the front arrives on that day.
If that day is very wet
then a rain depression is approaching, and if that day is very fine
then a strong high system.
A 30% chance of rain means
that 2 out of 3 of those days will be fine, and will vary depending on
the season
and with drought or wet periods.
The chance of rain can also be viewed as the relative weather instability.
During
the summer months a storm could be expected on a moon phase day, and about
half way between moon
phases, if there is
a strong NE wind and a low tide during the afternoon or evening.
High or low systems which
are well below the continent will bring cold air from the antarctic during
winter.
Because the number of days
between moon phases is not constant, the fronts can arrive early or late
Sometimes they arrive overnight
and often the next day.
There is also a minor front
about 3 days later. Expect a wind change with unsettled weather.
