Best Tide State to Fish Blackwall Reach (Swan River)

South-bank position, so the afternoon Fremantle Doctor blows across the reach and easterly mornings are calmest. The cliffs give some shelter from a southerly, but the fishing is governed by tide more than wind — slack water and the start of a tide let you hold bottom, while a hard run through the trench makes deep baits difficult. Water clarity is generally good and drops for a few days after heavy winter rain silts the upper river. The reach sees little swell compared with the open coast, but summer afternoons still put chop and boat wash across the rock ledges.

What Anglers Target Here

Anglers fishing Blackwall Reach (Swan River) typically time sessions around the tide for mulloway (jewfish), black bream, tarwhine, flathead, and tailor.
