Record tides dismissed as bilge water
GLADSTONE had the biggest tide in its history yesterday. But it wasn't seawater, despite what anecdotal opinion suggests.
According to Maritime Safety Queensland (MSQ,) a lot of 'bilge' was spoken about yesterday's so called record-breaking king tides.
'There's been a lot of nonsense going around about that right along the coast of Queensland,' MSQ's John Broadbent said.
Although it was true that Gladstone had a huge tide, and certainly the biggest in many months, tides almost as high as yesterday's were not out of the ordinary at this time of year, he said.
The waters along the Gladstone region's coast and the city's foreshores lapped the land at its high tide point at 9.20am registering 4.8 metres at the Auckland Point Wharf monitoring point.
But yesterday it was even rumoured that the tide was the highest it has been in 50 years.
'The highest in 50 years ? that's nothing,' Mr Broadbent said.
'Reports in Cairns claim the tide has been the highest there in living memory.'
Mr Broadbent said the highest tide usually came during the December to March months and depended on a lot of factors.
He said the height of the tides depended on cycles of the moon and the sun. If they were in line they had a greater combined pull.
Mr Broadbent said tidal records had been kept in Gladstone since January 1979.
Coincidently in that month the highest tide of 4.89 metres was recorded, but there had been a few higher tides than yesterday's in other years as well.
