More than 20 beaches have been closed or listed as unsafe across New South Wales as a “very dangerous” storm system lashes the coastline, bringing hazardous surf, intense rainfall and the risk of life-threatening flash flooding. Authorities are urging residents and visitors to stay out of the water and avoid exposed coastal areas as conditions worsen.
The storm has delivered short bursts of extremely heavy rain in parts of the state, overwhelming drains and creeks and prompting emergency warnings. At the same time, powerful swells have battered the coast, forcing councils and lifesaving services to shut beaches or suspend patrols as waves surge toward promenades, rock pools and foreshore walls.
Emergency advice: Avoid coastal rock platforms, do not walk or drive through floodwater, and stay indoors away from windows during severe weather. In life-threatening emergencies, call 000.
Why beaches are being closed or listed as unsafe
Beach closures and patrol suspensions are typically triggered when conditions become unsafe for the public and for rescue crews. During this storm event, authorities have cited hazardous surf, powerful currents, coastal erosion, debris in the water and poor water quality following heavy rainfall.
Officials warn that even experienced swimmers can be caught out when wave sets become unpredictable. Rock platforms and headlands are particularly dangerous during storm surges, with waves capable of sweeping people into the ocean without warning.
How beach closures are being tracked
Beach safety status across NSW is being monitored via Surf Life Saving Australia’s BeachSafe website , which provides patrol information, hazard warnings and real-time safety updates. During major storm events, beaches listed as “No patrol today” are considered unsafe for swimming and are treated as effectively closed.

- Newcastle Beach
- Bronte Beach
- Tamarama Beach

Officials said more than 20 beaches are affected statewide. The lists above reflect beaches specifically named in reports and those listed as unsafe on BeachSafe at the time of publishing.
Other coastal areas hit by extreme conditions
Severe coastal impacts have also been reported at several popular locations. In Sydney’s south, heavy swells at Wanda Beach were described as swallowing parts of the shoreline, while at Cronulla waves were seen pushing close to foreshore infrastructure and rock pools.
Authorities have urged people to stay well back from the water’s edge, even if rain eases temporarily, as large waves can arrive suddenly and without warning.
Storm conditions expected to continue
Meteorologists say showers and thunderstorms are likely to continue through the weekend in parts of NSW, with the potential for further severe storms bringing damaging wind gusts, heavy falls and large hail. Hazardous surf conditions are also forecast to persist along much of the coast.
Emergency services have already responded to hundreds of calls for assistance during the wild weather, including flood rescues involving vehicles trapped by rapidly rising water.
What residents and visitors should do now
- Stay out of the water at all closed or unpatrolled beaches.
- Do not drive through floodwater, even if it appears shallow.
- Keep clear of creeks and storm drains where water levels can rise rapidly.
- Secure loose items around homes, campsites and balconies.
- Check official updates frequently as conditions can change quickly.
For the latest warnings, residents are advised to monitor updates from the Bureau of Meteorology and follow guidance from emergency services. Beachgoers should also check local council notices and Surf Life Saving updates before heading to the coast.
