Does Moon Phase Affect Fishing? Everything You Need To Know
If you spend enough time around anglers, you will eventually hear someone talk about the moon. Some fishermen swear that a full moon brings better fishing. Others prefer a new moon. Some plan their trips around solunar charts, while others pay little attention to the lunar calendar. So, does moon phase affect fishing? Yes, the moon can influence fishing conditions, but it is not a guarantee that you will catch more fish. The moon affects tides, light levels, and the timing of some natural activity. These changes can influence where fish move and when they feed. However, moon phase is only one part of the picture. Weather, water temperature, tides, current, bait activity, water clarity, time of day, location, and the species you are targeting can all have a major effect on your results. The best way to use the moon is not to treat it as a magic fishing calendar. Instead, use it as one more piece of information when planning a trip. Key Takeaways What Is Moon Phase? The moon phase describes how much of the moon’s illuminated surface appears visible from Earth. The main phases are: The complete cycle takes about 29.5 days. The amount of moonlight and the position of the moon relative to the Earth and Sun change throughout this cycle. These changes can influence natural conditions in both coastal and freshwater environments. For fishermen, the most important connection is often between the moon and tides. How Does the Moon Affect Tides? The Moon’s gravitational pull is one of the main forces responsible for Earth’s tides. The Sun also contributes to tides, although the Moon has the larger influence because it is much closer to Earth. When the Sun, Earth, and Moon are positioned so their gravitational effects reinforce each other, the difference between high and low tide becomes greater. This happens around the new moon and full moon and produces what are called spring tides. About a week after a new or full moon, the Sun and Moon are positioned at roughly right angles relative to Earth. Their tidal effects partially oppose each other, producing neap tides, which have a smaller tidal range. This is important because moving water can influence feeding opportunities for many fish. Why Do Tides Matter to Fishing? The tide does more than simply make the water level rise and fall. Tidal movement also creates currents. As water moves, it can carry baitfish, shrimp, crabs, plankton, and other food sources. Predatory fish may position themselves in areas where moving water brings food within reach. This is why experienced saltwater anglers often pay close attention to when the tide is moving, rather than simply looking at whether it is high or low. NOAA notes that tides are accompanied by horizontal water movement called tidal currents, with flood currents occurring as the tide rises and ebb currents occurring as it falls. For fishing, that movement can sometimes be more useful than the moon phase itself. Is Fishing Better During a Full Moon? A full moon can create interesting fishing conditions, but it does not automatically mean better fishing. One reason anglers associate the full moon with good fishing is the combination of stronger spring tides and increased nighttime light. Some fish and prey species are more active at night under brighter conditions. Other fish may behave differently because they can feed during the night rather than relying as heavily on daylight. For anglers targeting certain species, this can change where fish are located or when they are actively feeding. But a full moon can also make fishing more challenging. If fish feed heavily overnight, they may be less active during the following morning. This is one reason some anglers prefer fishing during the night around a full moon rather than assuming sunrise will always be the best opportunity. There is no universal rule that a full moon equals better fishing. Is a New Moon Good for Fishing? The new moon is another period that many anglers watch closely. Unlike a full moon, a new moon produces very little visible moonlight at night. New moons also occur during spring tides, meaning the tidal range can be relatively large. For coastal anglers, the stronger tidal movement can create productive conditions in locations where current is important. The darker nights may also change the behavior of certain fish and prey species. Whether this improves fishing depends heavily on the species, location, tide, weather, and time of day. Does a Full Moon Affect Freshwater Fishing? It can, but the relationship is less straightforward than simply saying one moon phase is best. Freshwater fish do not experience ocean tides in the same way coastal fish do. However, fish can respond to changes in nighttime light and lunar cycles. Research on largemouth bass, for example, found that lunar phase was associated with changes in activity and depth distribution during many of the lunar cycles studied, although the patterns were not consistent throughout the year. The researchers also concluded that commonly used solunar tables had limited predictive value for identifying peak fishing times. That is an important point. The moon can influence fish behavior without providing a simple “fish will bite better on this date” rule. Does Moonlight Make Fish More Active? It can influence activity in some situations. Moonlight changes how much natural light is available at night. This can affect both predator and prey species. Some predators may find it easier to hunt under a brighter moon. Meanwhile, prey species may alter their behavior to avoid predators. These changes can affect where fish are located and when they feed. However, different species behave differently. A predator that benefits from hunting in brighter conditions may respond differently from a species that prefers darker environments. This is why moon phase should always be considered alongside the species you are targeting. What Are Solunar Tables? Solunar tables are fishing and hunting guides that use the positions and movements of the Sun and Moon to predict periods of potentially increased
