Several beaches along the New South Wales coastline have been shut down due to the impact of massive waves, as the state grapples with rainy weather and dangerous surf alerts this weekend.

Following a scorching heatwave last weekend, Sydney is now preparing for what could be the rainiest weekend of the summer, with surf conditions becoming increasingly perilous.

Reports indicate that waves at certain beaches, such as Sydney’s Curl Curl Beach, are reaching heights of up to five meters today.

The tumultuous sea state has led to the closure of numerous beaches along the NSW coast, including Newcastle, Bronte, Tamarama, Coogee, Cronulla, and Maroubra, as noted by Surf Life Saving Australia’s Beachsafe website.

“We haven’t dared to enter the water today. It’s incredibly rough,” a beach visitor shared with Today this morning.
