About This Spot
Cossack Beach is located in a protected bay on Western Australia's Pilbara coast, approximately 20km south of Roebourne. The spot features a northeast-facing bay with sandy beaches and shallow protected waters. The bay is partially enclosed by vegetated headlands and sandy spits, creating a sheltered environment with variable conditions. The water is typically choppy due to tidal influences and the shallow nature of the bay. Best conditions occur with northwesterly winds providing side-shore flow across the bay entrance. The spot suits beginners and intermediates seeking protected, shallow-water practice in a lower-wind environment. Water temperatures average 27.6°C year-round, supporting comfortable extended sessions. Key considerations include the low wind reliability (15%), shallow depths requiring awareness of sandbars and tidal cycles, and the presence of rocky areas on the eastern headland. The Cossack area is historically significant and receives minimal commercial traffic, offering a quiet practice venue.
