When to go

Year-round, peaking in summer. The bite is best after dark on a moving tide, especially the outgoing, and on the reef the week around the summer full moons. A slack tide at midday is the slowest time.

Best window on the day: The outgoing tide on the oceanside after dark. Today's window and score are on the conditions page.

June: Summer spawn: the biggest mangroves gather on the reef and wrecks.
July: Peak at the bridges after dark.

How to catch them

From the bridges, drift a live shrimp or a pilchard along the shadow line on a light knocker rig or free-lined with the current; let the fish run a moment, then reel tight. On the reef, chum and fish cut bait or small pilchards back in the slick; at night, a whole pilchard on the bottom near the structure.

Tips for your level

Fish the shadow line under a bridge at night: the snapper sit in the dark and ambush bait drifting past in the light.
Use the lightest leader that holds: mangroves see heavy line and refuse the bait.
A live shrimp on a small circle hook is all you need from the fishing bridges.

Keeping one

Excellent: firm, mild and the first choice for a fish fry. Minimum sizes differ inside and outside 3 nautical miles: see the rule card.

Keep only what you will eat, within the limit, and release the rest in the water where you can.
