The windows are set by the moon's transit and rise, and the forecast above already accounts for them: within these hours the bite score sits higher than across the rest of the day, while the day's overall level still comes from the catch-calibrated model.

Recommendations

Tactics

Chum one spot near a drop-off and wait for fish to arrive — don't chase them.

Lures

Today's bait — maggot or small hook with dough bait. In cold or murky water, add scent to your chum.

Gear

No special gear needed — seasonal clothing will do. Rain is expected — don't forget a rain jacket or a waterproof shell.
