How Do Moon Phases Affect Inshore Saltwater Fishing?

In the world of fishing, inshore saltwater angling is a highly specialized and often challenging endeavor. Inshore fishing involves targeting fish species that reside in the shallower waters closer to the coast, and it requires a unique understanding of the environment, tides, and other factors that influence fish behavior. One of the often-debated factors in inshore saltwater fishing is the impact of moon phases on fishing success.

In this comprehensive article, we will explore the relationship between moon phases and inshore saltwater fishing, delving into the science behind it and providing practical tips for anglers looking to maximize their catch during different lunar phases.

Understanding Moon Phases

Before we delve into how moon phases affect inshore saltwater fishing, let’s take a moment to understand the basics of lunar phases. The moon goes through a cycle of eight distinct phases, which can be grouped into four main categories:

  1. New Moon: During this phase, the moon is positioned between the Earth and the sun, with its dark side facing us. The new moon is not visible from Earth, as the illuminated side is facing away from us.
  2. First Quarter Moon: In this phase, the moon has completed approximately one-fourth of its orbit around the Earth. Half of the illuminated side is visible, forming a half-moon shape.
  3. Full Moon: At the full moon phase, the moon is positioned directly opposite the sun, with its entire illuminated side facing us. This is when the moon appears as a full circle in the night sky.
  4. Last Quarter Moon: During this phase, the moon has completed three-fourths of its orbit, and half of its illuminated side is visible, forming another half-moon shape.

These four phases represent the primary stages of the lunar cycle, but there are also intermediate phases such as waxing crescent, waxing gibbous, waning crescent, and waning gibbous that occur between the main phases.

The Influence of Moon Phases on Tides

To understand how moon phases affect inshore saltwater fishing, we must first recognize the relationship between the moon and tides. Tides are the rising and falling of sea levels caused by the gravitational pull of the moon and the sun on Earth’s oceans. The moon, being much closer to Earth than the sun, has a more significant influence on tides.

  1. Spring Tides: These tides occur during the full moon and new moon phases when the sun, moon, and Earth are aligned in a straight line. During spring tides, the gravitational pull of the moon and the sun reinforce each other, resulting in higher high tides and lower low tides. This increased water movement can influence fish behavior.
  2. Neap Tides: Neap tides occur during the first and last quarter moon phases when the sun and moon are at right angles to each other relative to Earth. During neap tides, the gravitational pull of the sun partially cancels out that of the moon, resulting in lower high tides and higher low tides. The water movement is less pronounced during neap tides.

Now that we have a basic understanding of the lunar phases and their connection to tides, let’s explore how these factors impact inshore saltwater fishing.

The Impact of Moon Phases on Inshore Saltwater Fishing

1. Full Moon

High Tide Fishing: During the full moon phase, anglers often experience higher high tides, which can be advantageous for inshore fishing. The increased water movement allows fish to access shallow areas they might not otherwise frequent during lower tides. This can lead to excellent fishing opportunities in shallow flats, marshes, and estuaries.

Increased Visibility: The bright illumination of the full moon can also make it easier for anglers to see and target fish during night fishing expeditions. Many species of inshore fish are more active at night, and a well-lit night can be productive for those who know how to take advantage of it.

Cautious Fish: On the flip side, some anglers argue that during the full moon, fish can become more cautious and less likely to strike at lures or baits. They may be more wary of predators due to the increased visibility, so finesse and stealth in your approach can be crucial during this phase.

2. New Moon

Stronger Currents: During the new moon, when the sun and moon are aligned, anglers can expect stronger tidal currents. This increased water movement can concentrate baitfish and other prey, making it an excellent time for predatory inshore species like redfish, snook, and trout to feed.

Night Fishing Advantage: Similar to the full moon, the new moon phase provides a well-lit night sky, making it conducive to night fishing. Anglers can take advantage of the increased activity of nocturnal fish species.

Challenging Visibility: While the strong currents can benefit fishing, the lack of moonlight can make navigation and targeting fish more challenging. Using high-quality navigation equipment and understanding your fishing grounds are essential during this phase.

3. First and Last Quarter Moon

Moderate Tides: The first and last quarter moon phases, associated with neap tides, offer moderate tidal conditions. This can be a good time for anglers who prefer more stable water levels for sight fishing in shallow areas.

Balanced Conditions: During these phases, fish might be less affected by extreme tidal fluctuations, allowing them to remain in familiar areas. It can also be an excellent time for wade fishing in coastal flats.

Varied Fish Activity: Fish behavior during the first and last quarter moon can vary depending on other factors like water temperature and baitfish availability. Anglers may need to adjust their tactics and locations based on the specific conditions of the day.

4. Intermediate Phases

The waxing crescent, waxing gibbous, waning crescent, and waning gibbous phases occur between the main moon phases and are associated with changing tidal conditions. These phases may present a mix of opportunities and challenges for inshore saltwater anglers, depending on the specific tide and fish behavior patterns. Being adaptable and willing to experiment with different techniques and locations is key during these intermediate phases.

Tips for Maximizing Your Catch during Different Moon Phases

Now that we have explored the influence of moon phases on inshore saltwater fishing, let’s discuss some practical tips for anglers looking to optimize their fishing success during each lunar phase.

Full Moon Fishing Tips

  1. Fish Shallow Areas: Target shallow flats, marshes, and estuaries during the full moon’s higher high tides. Look for signs of baitfish activity in these areas.
  2. Use Bright Lures: Brightly colored lures can be effective during the full moon, as they are more visible in the increased light. Consider using topwater lures and surface plugs for visually striking strikes.
  3. Practice Stealth: With fish potentially being more cautious due to increased visibility, use a stealthy approach. Wear clothing that blends with the surroundings, and make quieter movements.
  4. Fish at Night: Take advantage of the well-lit night skies for night fishing. Many inshore species become more active and feed aggressively during the night.

New Moon Fishing Tips

  1. Focus on Strong Currents: Concentrate your fishing efforts on areas with strong tidal currents, such as passes, channels, and river mouths. Predatory species are often more active in these conditions.
  2. Use Scented Baits: To compensate for reduced visibility, consider using scented baits that can attract fish by smell. Soft plastics infused with scent or natural baits like shrimp and cut bait can be effective.
  3. Be Safety-Conscious: Due to the lack of moonlight, navigation can be challenging. Ensure you have reliable navigation equipment, and be cautious when boating or wading in unfamiliar areas.

First and Last Quarter Moon Fishing Tips

  1. Sight Fishing Opportunities: Take advantage of the moderate tides during these phases for sight fishing in shallow waters. Polarized sunglasses can help you spot fish more easily.
  2. Be Patient: Fish behavior during these phases can be less predictable. Be patient and prepared to adapt your strategy based on the conditions and fish activity.
  3. Wade Fishing: Consider wade fishing in areas with consistent water levels. This can be a productive way to target fish during the first and last quarter moon.

Intermediate Phase Fishing Tips

  1. Experiment: Since the intermediate phases come with changing tidal conditions, be open to experimenting with various techniques, lures, and locations to adapt to the conditions of the day.
  2. Monitor Weather: Pay attention to weather forecasts, as weather patterns can influence fish behavior during these phases. Sudden weather changes may trigger feeding activity.
  3. Keep Records: Maintain a fishing journal to record your experiences during different lunar phases. Over time, you may identify patterns specific to your local waters.


Moon phases play a significant role in inshore saltwater fishing, influencing tides and fish behavior. Anglers who understand these lunar dynamics can strategically plan their fishing trips and adapt their tactics to maximize their catch. Whether you prefer fishing during the full moon’s high tides, the strong currents of the new moon, the stability of the first and last quarter moon, or the changing conditions of intermediate phases, there are opportunities to catch a variety of inshore species throughout the lunar cycle.

Ultimately, successful inshore saltwater fishing requires a combination of lunar knowledge, angling skills, and a deep connection with the coastal ecosystem.
