Arthur River is a coastal river mouth location in southwestern Victoria, Australia, where a substantial river system meets the Southern Ocean. The spot features a wide river estuary with sandy banks and dark tannin-stained water typical of southern Australian rivers. The coastline faces northwest toward the water, with the river creating a defined channel between forested banks and residential development on the eastern side. This is primarily a river-based spot rather than pure ocean kitesurfing, offering protection from extreme ocean swell but subject to tidal and river flow dynamics. Best wind direction is northeast to east (around 45°), providing side-shore conditions parallel to the river mouth. The spot suits intermediate kiters comfortable with variable river conditions, tidal considerations, and narrower water channels. Wind reliability is relatively low at 24.5%, and average wave heights of 2.83m suggest modest swell penetration. Water temperature averages 13°C, requiring appropriate thermal protection. Key considerations include monitoring tidal cycles affecting river flow, respecting residential proximity, and understanding shifting sand formations in the river mouth area.
