There is only one High and one Low tide each day in the Gulf of Carpentaria, except for Neaps each fortnight, when we have Double Tides.
The tidal variation can be up to 4 metres, with strong currents around headlands and over undersea channels. Strong Southeasterly
Trade Winds in June-July can affect tide levels, sometimes resulting in high tide being half a metre lower than expected.
If you are planning to travel to Sweers Island in a private boat please ensure that the skipper is experienced in open waters, and that all regulation safety equipment is carried on board. Check tide times for Burketown as you may have to plan your trip carefully in order to be able to cross the shallow sandbars at the mouth of the river. Note that SE winds can result in lower than normal tides.
