Herbertville is a remote coastal settlement in southern Hawke’s Bay near the boundary with Manawatū–Whanganui, facing the open Pacific Ocean. Sea temperatures here follow a typical lower east coast pattern.

Through spring the ocean slowly warms to around 14–16°C. Summer, from December to March, brings the most comfortable conditions, with water temperatures commonly sitting between 18–21°C during settled weather.
