TIDES have peaked across south-east Queensland, reaching about 2.77 metres at Cleveland Point.
Authorities had warned people to be careful of strong currents caused by stronger tidal flows during king tides.
Transport Minister Bark Bailey said novices were sometimes caught out by wider tidal rangers, especially when launching and retrieving.
“Tidal ranges on Queensland’s coast can be quite significant,” he said
“Keep a close watch over children playing in shallow water. Tidal streams in these waters can be strong.”
Today’s king tide happened about 10.45am, with a low tide of 0.36 metres predicted for just after 5pm at Cleveland Point.
Redland City Council advised earlier today that waste and recycling services would be later than usual at Russell Island because of abnormal low tides.
King tides happen twice every year and are influenced by the moon’s cycle and earth’s position to the sun.
According to Maritime Safety Queensland, the highest tides of the month occur during a new moon and full moon.
These are called spring tides, occurring about once every two weeks.
The two highest spring tides in a year are called king tides and these occur once in summer and in winter.
Mr Bailey said king tides in winter were not as obvious as those in summer as they happened at night.

Tides are created by the gravitational pull of the moon, and to a lesser degree, the sun.
A super moon could be spotted in Brisbane skies overnight, appearing large and bright.
The phenomenon happens when a full moon occurs on the moon’s closest approach to earth.
Night sky observers in the Americas and Western Europe were treated to a super blood wolf moon eclipse.
The name describes a lunar eclipse that happens during January’s full moon when the moon is closer to earth than usual.
The red coppery glow projected onto the moon was caused by sunlight travelling through Earth’s atmosphere.
Observers in Australia missed out on the phenomenon.
The next lunar eclipse able to be seen from Australian soil is predicted for May 2021.
