Annual Water Temperature Trend

Aireys Inlet sits along the open Surf Coast, fully exposed to the cooler waters of Bass Strait, and this strongly shapes local water temperatures. In summer, the sea is generally at its warmest, usually around 17–20°C, which feels brisk but refreshing on hot days. As autumn arrives, temperatures tend to fall to about 15–18°C, while winter brings much colder conditions, often in the 12–14°C range. Spring is typically slow to warm, with water temperatures commonly sitting between 13–16°C, and short cold spells can follow strong southerly weather.
