What wind and swell should I expect today?
Southerly winds of 20–30 km/h are common in the afternoon, dropping to 10–15 km/h overnight. Swell from the south-west typically reaches 0.5–1.5 metres, building when a low-pressure system passes to the south. The live forecast above shows the latest wind gust and wave height — use these to decide whether to launch a boat or fish from the jetty.
How does Moonta Bay compare with nearby towns?

Temperatures here are usually 2–3°C cooler than in Adelaide weather readings due to the coastal influence. For longer-range planning, check the moonta bay weather 14 day forecast or the weather in moonta 10 days for rainfall trends.
