Keep close watch on coast during king tides plus a cold snap
Owners of boats and properties with ocean or river frontages on Queensland’s South East coast should prepare for king tides over coming days.
Transport and Main Roads Minister Mark Bailey said higher tides were already being experienced as they approached maximum ranges.
“Spring tides are a regular and familiar event for experienced local boaties,” Mr Bailey said.
“The highest winter tides of 1.93 metres on the Gold Coast and 2.74m metres on Brisbane Bar on July 13 are at night and not as obvious as those in the summer which generally occur during the day.”
“However novices may be caught out by the wider tidal ranges especially when launching and retrieving,” Mr Bailey said.
“Tidal ranges on Queensland’s coast can be quite significant.
“This is especially the case in our more northerly ports where the highest tides of the season are expected next month.
“For example Townsville is predicted to reach its highest tide at 9.24pm on August 11 at 3.97 metres with Cairns hitting 3.34 metres about 20 minutes later.
“Maritime Safety Queensland regularly reminds boaties to check tides as published in the local press, on local fishing and boating web sites or at Maritime Safety Queensland.
“And remember, severe weather such as heavy rainfall or cyclones can cause these sea levels to be elevated above the expected heights.
“There is the possibility of low-lying roads and trails going under especially if the tides coincide with high rainfall or storms as are currently being experienced in the far north of the state.
“Concerned residents should contact their local councils for advice about these low lying locations and remember ‘If it’s flooded forget it.’
“People living close to the water who may be affected by these tides should move tinnies, kayaks, garden furniture and other items away from the water’s edge.
“Keep a close watch over children playing in shallow water – tidal streams in these waters can be strong.”
Tides are predicted in a range of tidal information publications including the ‘Queensland Tide Tables 2018’ which is available on Maritime Safety Queensland’s website.

The Bureau of Meteorology is also predicting a cold snap this weekend as South East Queensland and Moreton Bay Region will experience its coldest nights so far this year.
The Bureau of Meteorology has forecast a low of 6C overnight on Friday and Saturday in Brisbane, which could fall below this year’s previous record low of 6.9C on June 16.
The Gold and Sunshine Coasts will also hit 6C while Ipswich will get even colder, hitting zero on both Saturday and Sunday.
It comes almost three years to the day since an “Antarctic vortex” covered Queensland in a layer of frost.
High Tides at Beachmere for Friday 10:14 pm (2.74m), Saturday 10:31 am (1.97m) & 11:02 pm (2.74m), Sunday 11:23am (1.97m) & 11:49 pm (2.68m), Monday 12:15 pm (1.96m), Tuesday 12:36 am (2.56m) & 1:07 pm (1.94m)
King tides are simply the very highest tides.
They are naturally occurring, predictable events.
Tides are the movement of water across Earth's surface caused by the combined effects of the gravitational forces exerted by the Moon, Sun, and the rotation of Earth which manifest in the local rise and fall of sea levels.
Concerned residents should contact their local councils for advice about these low lying locations and remember ‘If it’s flooded forget it.’
