How Heavy Rains and Salinity Levels Affect Fishing

When most people plan a fishing trip, they don’t take into account external factors such as the weather and the changing season and how it may affect the fish.

If you’re going on a fishing trip, stop before you pack the gear and head out to the water. Ask yourself—is it going to rain today? What is the condition of the water? Is the salinity too high or low to affect the existence of fish species I’m looking for?

If you’re wondering how heavy rain and water salinity levels can affect fishing, read more to find out how.


Heavy rains

We may not notice it, but an expert fisherman knows that weather patterns have begun changing more frequently and with increased intensity. One second you have blue skies, and the next thing you know you’re stuck with howling wind and a ringing in your ears.

Heavy rain doesn’t affect the fish directly, but it does impact the surrounding environment, which ultimately affects the way you fish. The environment reacts strongly to atmospheric conditions and the barometric pressures shift due to precipitation. While not an exact science,  the barometric pressures does affect feeding activity. Studies show that fishing is best when barometric pressures are between 29.5 and 30.5.

Hence, when fishing before or after heavy rain, pay attention to barometric pressure and be prepared for changing weather conditions and how heavy rainfall and runoff affect salinity levels in the bay.

Water salinity

Water salinity is the total dissolved salt present in the water. The fluctuations in water salinity are brought about by several factors—high precipitation can lower the concentration of the salt in the fish; whereas a hot summer day can result in a high concentration as more water will be evaporated due to the rising temperatures.

Studies have shown that water salinity affects fish’s development—some species thrive in saltwater, whereas others are freshwater fish where the salt concentration in water is lower. In addition to that, it also affects a fish egg fertilization, yolk sack, and incubation. Due to this, Galveston Bay fish species, such as Speckled Trout, will move to waters with salinity levels that are conducive to their livelihood.

Now that you know the basics about how rainfall and water salinity affects the fish, you can better determine the best time to go on a fishing trip with the help of a bay fishing charters in Galveston TX.
