Hey I'll bite
a King tide of 2.65 m is predicted for 1037 hrs on 21 Jan
at 0551 Sat 15 Jan the tide will be predicted at 1.98m
and 2.55 M by 0911 Wed 19 Jan
So they are rising each day till the actual king tide, all of which will have an effect on how much water exits the
Brisbane River system in the coming days

Hello,
KING tides are created when the sun and the moon are in alignment with the earth and pull together.
ie, If the moon is on the horizon and the sun is on the horizon[Does not matter which horizon] then they are aligned and will pull together to create a KING tide.
When say the sun is overhead and the moon is on the horizon then they cannot pull together and you get smaller or NEAP tides.
They occur usually twice a month each.
regards
Guy

Actualy you have described Spring tides:
King tide is the popular name for an especially high tide. The phrase is used mostly in Australia and other Pacific nations.
In the lunar month, the highest tides occur roughly every 14 days, at the new and full moons, when the gravitational pull of the moon and the sun are in line. These are called spring tides.
On Australia's East Coast, the highest tides occur during the winter months of June, July and August, and the summer months of December, January and February. The highest of each of these periods (i.e., one in winter and one in summer, totalling two per year) are known as the king tides.

You've been hanging out with Norrie again, haven't you Pete?

I have lost touch with Norrie - but he was a good mate. It is amazing how much of his excellent advice has stuck in my mind. However the info above came from wikipedia.
I still have a copy of the mariner's handbook at
home - and a star globe that somehow became the captain's property when they were discontinued in preference for those silly plastic widgets.
On tides, I remember the first time I was in
Broome as X of the Witch. We arrived at the top of a king tide and I stepped off the main deck onto
the wharf and took off with fisheries. When I came back 6 hours later I though the boss had sailed without me - only the satnav antenna was visible above
the wharf. Do you remember using the extension ladder from the boat to the bottom of
the wharf ladder there?
And then there was that time during the shake down for the 'gong when that clown made us jump off
the wharf at
Darwin at low tide ...
Cheers
Pete
