Barometric pressure is the weight of the air above a given point on the Earth’s surface. It is measured in millibars (mb) or inches of mercury (inHg). When the barometric pressure is high, the air is heavy and dense. When the barometric pressure is low, the air is light and less dense.
Fish are sensitive to changes in barometric pressure. When the barometric pressure drops, the fish’s swim bladders expand. This causes the fish to rise in the water column. When the barometric pressure rises, the fish’s swim bladders contract. This causes the fish to sink in the water column.
The change in barometric pressure can also affect the fish’s feeding habits. When the barometric pressure drops, the fish are more likely to feed. When the barometric pressure rises, the fish are less likely to feed.
Fishermen can use barometric pressure to help them catch fish. By understanding how barometric pressure affects fish, fishermen can choose the best time to fish and the best location to fish.

Weather conditions
Weather conditions play a significant role in determining how barometric pressure affects fishing. High-pressure systems are associated with stable weather conditions, clear skies, and calm winds. These conditions make it easier for fish to find food and move around, leading to increased activity and better fishing. Conversely, low-pressure systems bring cloudy skies, rain, and strong winds. These conditions can make it harder for fish to feed and navigate, resulting in decreased activity and poorer fishing.
One of the most important weather conditions to consider when fishing is wind speed. Strong winds can create waves and choppy water, making it difficult for fish to see and feed. Additionally, strong winds can make it difficult for anglers to cast their lines and control their boats. As a general rule, fishing is best when the wind speed is low.
Another important weather condition to consider is water temperature. Fish are cold-blooded animals, and their body temperature is largely determined by the temperature of the water they live in. When the water temperature is high, fish are more active and feed more frequently. Conversely, when the water temperature is low, fish become less active and feed less frequently. As a result, fishing is generally better in warm weather than in cold weather.
By understanding how weather conditions affect barometric pressure and fish behavior, anglers can increase their chances of catching fish. For example, if the weather forecast calls for high-pressure conditions, anglers should expect good fishing. Conversely, if the weather forecast calls for low-pressure conditions, anglers should be prepared for slower fishing.

When the barometric pressure is high, the air is more compressed and the water is clearer. This allows fish to see more easily, which can make them more active and willing to feed. As a result, fish are often more likely to be found near bottom structure when the barometric pressure is high.
Conversely, when the barometric pressure is low, the air is less compressed and the water is murkier. This makes it more difficult for fish to see, which can make them less active and less likely to feed. As a result, fish are often less likely to be found near bottom structure when the barometric pressure is low.
Understanding the relationship between barometric pressure and bottom structure can help anglers increase their chances of catching fish. For example, if the barometric pressure is high and the water is clear, anglers should focus on fishing near bottom structure. Conversely, if the barometric pressure is low and the water is murky, anglers should focus on fishing away from bottom structure.
Tides
Tides are the rise and fall of the sea level caused by the gravitational pull of the moon and sun. Tides can have a significant impact on fishing, as they can affect the behavior of fish. Fish are often more active during high tide, as the rising water level brings in more food and creates more favorable feeding conditions. Conversely, fish may be less active during low tide, as the receding water level can make it more difficult for them to find food.
-
Tidal currents
Tidal currents are the horizontal movement of water caused by tides. Tidal currents can affect the behavior of fish, as they can carry food and bait to fish. Fish are often more likely to be found in areas with strong tidal currents, as these areas are more likely to have abundant food.
-
Water temperature
Tides can also affect the water temperature. High tide often brings in warmer water, which can attract fish. Conversely, low tide can bring in colder water, which can make fish less active.

Bottom structure
Tides can also affect the bottom structure. High tide can cover up bottom structure, which can make it more difficult for fish to find shelter and food. Conversely, low tide can expose bottom structure, which can make it easier for fish to find shelter and food.
Understanding the relationship between tides and barometric pressure can help anglers increase their chances of catching fish. For example, if the barometric pressure is high and the tide is high, anglers should focus on fishing in areas with strong tidal currents. Conversely, if the barometric pressure is low and the tide is low, anglers should focus on fishing in areas with clear water and exposed bottom structure.
Moon phase
The moon phase is the shape of the illuminated portion of the moon as seen from Earth. It is determined by the relative positions of the sun, moon, and Earth. The moon phase has a significant impact on barometric pressure, which in turn affects fishing.
When the moon is full, the gravitational pull of the moon and the sun are aligned, which causes high tide. High tide brings in more food and creates more favorable feeding conditions for fish. As a result, fish are often more active and easier to catch during a full moon. Conversely, when the moon is new, the gravitational pull of the moon and the sun are opposed, which causes low tide. Low tide brings in less food and creates less favorable feeding conditions for fish. As a result, fish are often less active and more difficult to catch during a new moon.
Understanding the relationship between moon phase and barometric pressure can help anglers increase their chances of catching fish. For example, if the barometric pressure is high and the moon is full, anglers should focus on fishing in areas with strong tidal currents. Conversely, if the barometric pressure is low and the moon is new, anglers should focus on fishing in areas with clear water and exposed bottom structure.
