Lorne sits tucked into a natural bay along the Great Ocean Road, facing the waters of the Great Australian Bight near Cape Otway, and this setting shapes local water temperatures.

Through autumn, temperatures usually ease back to around 16–19°C, while winter brings colder conditions, often in the 13–15°C range. Spring is a gradual transition, with water temperatures commonly sitting between 14–17°C, influenced by weather patterns and ocean swells.
