Gold Coast beaches will continue to cop a battering today despite Cyclone Seth being downgraded to a sub-tropical low.
The system is currently located over the southern Coral Sea and is forecast to adopt a west to northwesterly track, approaching the Queensland coast during the first half of the week.
The Bureau of Meteorology warns the system is generating increasing seas and swell, which will coincide with an astronomical peak in high tides.

Water levels on the high tide may exceed the highest astronomical tide of the year by more than 0.5m on the Gold Coast and other areas around the southeast on Monday and Tuesday mornings.
The increasing easterly swell is combining with strong to gale force winds to generate deep water wave heights at or above 4m which will lead to dangerous conditions along the coast until Tuesday.
Low-lying areas have been warned there could be some minor flooding as a result of the conditions.
The majority of Gold Coast beaches were closed on Sunday and they are likely to remain shut on Monday.
City of Gold Coast has said many beaches have already experienced erosion that will get worse over the coming days. Crews will be sent in when it’s safe to do so to conduct repair work.
BOM has also issued a separate Severe Weather Warning for southeast Queensland for damaging winds.
Wind gusts with peaks of around100 km/h are possible over coastal areas and ranges across far southeast Queensland from mid-afternoon on Monday and are expected to ease during the day on Tuesday.
