Enter your trip dates to see the moon phase and illumination for each day — and which days are most likely to produce feeding fish.
The moon's gravitational pull affects water pressure across all bodies of water, including inland lakes and rivers. Many experienced carp anglers report that feeding activity peaks in the 2–3 days either side of a full moon or new moon — these are the Prime periods in the calendar above.
The full moon brings increased light at night which can trigger intense nocturnal feeding, sometimes reducing daytime activity. The new moon often produces confident daytime feeding as fish are less light-wary. Quarter phases — when the moon appears as a half disc — are traditionally the slower periods.
As always, weather, temperature, bait choice and venue knowledge matter just as much. Use the lunar calendar as one more tool in your planning, not the only one.
