What should swimmers and beachgoers know?
Sea breezes will keep the coast comfortable, but UV levels are high (index 8–10) around midday – sunscreen and shade are advisable. The cronulla weather radar (via BOM) is useful for tracking any afternoon storms, which are possible on 2–3 days. Swell conditions are generally moderate, but check local surf reports for rip currents.

Light to moderate easterly sea breezes are typical, around 15–25 km/h in the afternoons. No strong wind warnings are in the current 10-day outlook from the live forecast above.
