Stockton Beach accessways will be closed and road blocks may be installed in preparation for a possible east coast low predicted to hit Newcastle and the Hunter this week.
City of Newcastle has implemented safety precautions ahead of the low which has been forecast to build on Monday and Tuesday.
The low-pressure system is expected to linger off the coast Tuesday and Wednesday with potential for heavy rain, strong winds and large waves which will pose risks along Newcastle's coastline.
The Bureau of Meteorology has issued a hazardous surf warning for the Hunter on Tuesday. Swell conditions are expected to be hazardous for swimming, surfing and rock fishing for all beaches and both ocean baths from Tuesday until Friday.
Director of Lifesaving at Surf Life Saving NSW, Joel Wiseman said that conditions along the coast will be very dangerous for the next few days.
"During this extreme weather event we urge members of the public to stay away from the coastline and not to engage in risky coastal activities," Mr Wiseman said. "If people put themselves in danger in these extreme conditions, there's a real possibility that lifesavers will not be able to save them."
With sea swells up to four metres forecast, heavy rain and damaging winds in some locations, there is a chance of coastal inundation, erosion and flooding in low-lying areas.
City of Newcastle will prepare and monitor its coastal facilities and assets along the coastline including areas in Stockton which may be impacted by coastal erosion.
Beach accessways in Stockton will be closed and current traffic controls in place at Barrie Crescent and Mitchell Street will be reinforced. Road closures at Barrie Crescent, Mitchell Street, Stone Street Corner and Griffiths Road may be implemented depending on weather conditions.

The City of Newcastle asks the community to follow all safety warnings, to abide by all road closures and to drive safely in the forecast extreme weather conditions.
Coastal erosion can change beach conditions dramatically and quickly. This can lead to sand cliff collapses without warning.
