Information

The barometer is without doubt the most useful instrument with which to predict the weather. Cursed and loved for centuries past. Admiral FitzRoy learnt almost to his cost the great advantage a barometer was whilst sailing. He attributed the near loss of HMS Beagle during is first voyage to not taking enough attention to the barometer. He probably became the greatest champion of the barometer from that time onward and righty was the ideall person to become the first head of the newly formed Met Office under the Board of Trade in 1854.

Use Of Barometers For Fishermen

It has been well known that barometric pressure changes, as shown by a barometer, affect fishing and the way fish behave, especially game fish because of the neutral buoyancy of their swim bladders.

Low air pressure will cause the fish to go slightly deeper using a greater head of water to compensate and continuing high pressure tends to cause fish to rise.

If the air pressure is at 1010 millibars & above and rising, very good fishing can be expected.

If the pressure is below 1010 millibars and rising, fishing will be poor but improving.

If the pressure is above 1010 millibars and steady, good fishing can still generally be expected.

If below 1010 millibars fishing will normally be poor but may improve if the barometer remains steady for several days.

If the barometer is falling from above 1010 millibars the fishing will become poor.

If the air pressure is below 1010 millibars and falling then fishing is likely to be very poor.

The best fishing is likely to be when the air pressure is between 1010 & 1022 millibars and the barometer is in a rising or steady state.

Tight lines to you all!
