Pressure Affect Fishing Results

  • by

Every angler usually knows how the tides, temperature, lighting level and moon phase can affect our fishing results.

However, there is actually another factor that is often not taken into account at all, which is barometric pressure.

Although barometric pressure (or atmospheric pressure) cannot be predicted as precisely as other elements, it is able to exert a great influence on the attitude and behavior of fish.

Try to think back:

How often do you enjoy catching fish before a bad weather or storm

Or have you ever experienced a mysterious situation when the Database fierce fish suddenly went silent as soon as bad weather arrived?
And how long will the fish come back after the storm has passed?

What Is Barometric Pressure?
barometric pressure

Barometric pressure means the weight or mass of the entire column of air per unit surface area at sea level.

The barometer is also a tool for observing the weather, because its fluctuation shows that the weather is changing.

Liquid mercury (Hg) is commonly used in barometers to measure air pressure changes in inches (in.).

Atmospheric pressure (air) may also be measured in millibars (mb).

Where one bar roughly equals one atmospheric pressure one atmosphere equals


One bar equals 29.60 inches of Hg.
A barometer that reads 30 inches (Hg) is considered normal.
Strong high pressure can reach as high as 30.70 inches.
While low pressure associated with hurricanes can drop Business Lead below 27.30 inches
Usually weather conditions such as cold wind, hot wind, or rain – will cause low atmospheric pressure.

Briefly; A high barometer reading lowers sea level, a low reading increases sea level
On the other hand, high atmospheric pressure usually occurs after the weather mentioned above has passed.

When high pressure occurs in an area, it usually means sunny days and relatively calm seas.

How does barometric pressure affect fish?

Fish detect changes in pressure through their air bladders.
