Best tide state to fish Bunbury Koombana Bay (Inner Harbour / The Plug / Casuarina Boat Harbour)

North-facing and tucked behind the harbour breakwaters, so Koombana Bay shelters from the prevailing south-westerly weather that shuts down the open coast. Off-shore easterly holds the surface clean for the morning window; afternoon sea breezes blow across the bay but are softened by the bay shape. Tide changes lift the squid and KGW bite; slack water is slow. Water clarity holds clear most days — clouds up after heavy rain or a strong northerly that stirs the seagrass. The Collie River discharge gives the inner end of the bay a slightly tannin tinge after winter rains.
