Merewether Beach is patrolled by surf lifesavers during summer months and weekends, making it generally safe for swimming between the flags. The beach experiences consistent surf, with waves ranging from moderate to large, which can create strong rip currents. Beginners should stay in the flagged areas and check conditions with lifeguards. The ocean baths at the southern end provide a safer alternative for calm swimming. Always check surf reports before entering the water, especially during winter when patrols are limited.

Merewether Beach is enjoyable year-round, with each season offering different appeals. Summer (December-February) brings warm weather ideal for swimming, though crowds peak during weekends and holidays. Autumn and spring offer pleasant temperatures and excellent surfing conditions with fewer visitors. Winter (June-August) attracts serious surfers due to bigger swells but requires wetsuits for water activities. Early mornings provide the calmest conditions and stunning sunrises. The beach hosts major surfing competitions in February, drawing international attention to Newcastle's surf culture.
