Anglers catch more fish when they have knowledge about their subject. Good anglers know a lot about the fish and ecosystem in the waters where they fish.
They can catch even more fish with knowledge of the specific weather patterns for each season and technology, including a barometer, available to them.
If you are planning to use a barometer on your next fishing trip, here are a few things you should know.
1) Barometric Pressure
Barometric pressure is the measure of the weight of the air above a particular area. It is generally higher at lower elevations and lowers at higher elevations.
There are many factors that affect barometric pressure. It depends on latitude, altitude, air temperature and weather conditions.
In general, as the temperature decreases, so does the pressure. However, this is not a constant; the changes in pressure are not in direct relationship to the temperature.
2) The Best Times for Fishing
The length of the day influences the water temperature and then the fish that are most active. As the sun passes overhead, the water is warmed and fish will become active.
They will begin to feed as the barometric pressure rises, as the day grows longer and as the air temperature rises.
As the day ends, the water cools and the fish become less active; they will feed less or feed less energetically.
A barometer is useful in determining the direction of currents. There is an association between barometric pressure, altitude and wind directions.
As the barometric pressure increases, there is usually wind out of the south or southwest. When the barometric pressure decreases, there is usually wind out of the north or northeast.
The Coriolis effect will influence the direction in which the wind blows. The Coriolis effect is best described as the earth's rotation.
4) Sea Surface Height
As the barometric pressure drops, however, the wind can blow out of the northeast for just a few days before changing again to the south or southwest.
The wind blows from the direction of the higher pressure, from the direction of the lower pressure and from the direction between the two pressure centres.
5) Upwelling and Downwelling
When the barometric pressure rises, the winds blow from the direction of the lower pressure, away from the higher pressure. When the pressure drops, the wind blows from the direction of the higher pressure, toward the higher pressure.
Barometric pressure can be used to anticipate the direction of upwelling and downwelling, which are the result of differences in air and water temperatures.
When the barometric pressure is high (water is cold), there is an upwelling of cool water because the winds are blowing from the direction of the higher pressure.
During a low pressure, the winds will blow toward the low pressure; the result is downwelling.
The wind and barometric pressure also determine the direction of wind and water currents and then the direction in which fish will move. You need to know how to use a barometer in order to know how these currents will affect the fish.
A barometer is a great tool for anglers who want to catch a lot of fish. It is especially useful in determining the perfect times to fish and the best times for the fish to be most active, feed and leave their beds.
