Coastal Hazard Warning
for ABNORMALLY HIGH TIDES
for parts of Adelaide Metropolitan, Mount Lofty Ranges, Lower Eyre Peninsula, Eastern Eyre Peninsula, Yorke Peninsula, Mid North and Flinders districts.
Issued at 10:28 pm Sunday, 25 May 2025.
Abnormally High Tides expected for South Australia.
Weather Situation
A strong cold front associated with a deep low pressure system to the southwest of Kangaroo Island will move over gulf waters during Monday. Strong to gale west to northwesterly winds will turn west to southwesterly during Monday afternoon and evening.
ABNORMALLY HIGH TIDES for the following areas:
Adelaide Metropolitan, Mount Lofty Ranges, Lower Eyre Peninsula, Eastern Eyre Peninsula, Yorke Peninsula, Flinders and Mid North
ABNORMALLY HIGH TIDES are likely to lead to sea water FLOODING OF LOW-LYING COASTAL AREAS in Spencer Gulf and Gulf St Vincent on Monday. Tides are likely to rise SIGNIFICANTLY ABOVE the normal high tide mark during the Monday afternoon and evening high tide.
At the Outer Harbor tide gauge, the sea level is forecast to reach 3.8 metres above the lowest astronomical tide (LAT). At the Port Pirie tide gauge, the sea level is forecast to reach 4.5 metres above the lowest astronomical tide (LAT). This is expected to cause sea water flooding of low lying areas.
Large surf in combination with the elevated sea levels may also lead to coastal erosion and localised damage to coastal infrastructure, including about the Adelaide metropolitan beaches. Beach conditions in these areas could be dangerous and people should stay well away from the surf and surf exposed areas.
A separate warning for DAMAGING TO LOCALLY DESTRUCTIVE WINDS is current. Please refer to http://www.bom.gov.au/warnings/
Locations which may be affected include Port Adelaide, the Adelaide metropolitan beaches, Port Pirie, Port Lincoln, Whyalla, Port Augusta, Wallaroo, Victor Harbor and Port Wakefield.
The State Emergency Service advises the following:
* Unusually high tides are dangerous to swimmers, surfers and rock fishers. Stay away from coastal areas until conditions subside.
* Know your limitations around beaches, tidal rivers and creeks. Monitor warnings and conditions. Supervise children at all times.
* If you have a moored boat or watercraft, check that your mooring and lines are secure.
* Be aware that unusually high tides could cause flooding at the coast.
* You should never walk, ride or drive through floodwater.
The next Coastal Hazard Warning will be issued by 5:00 am ACST Monday.
Warnings are also available through TV and Radio broadcasts, the Bureau's website at www.bom.gov.au or call 1300 659 210. The Bureau and State Emergency Service would appreciate warnings being broadcast regularly.
