Atmospheric pressure forecast

An atmosphere (atm) is actually a unit of measurement equivalent to the average air pressure at sea level with a temp of fifteen degrees Celsius (59 degrees Fahrenheit). Atmospheric pressure is usually recorded using a barometer. 1 atmosphere is 1,013 millibars, or 760 millimeters (29.92 inches) of mercury.

For many years, fishermen have watched the increasing or decreasing atmospheric pressures to forecast fish activity and feed spots.

Rising barometric pressure, weather conditions are rather clear or bettering. Fish movement becomes a little more active. When the ascending weatherglass gets a top point, the sky is clear with generally shiny light. During this period, activity is mostly reduced, because the fish find protection or swimming into deeper water.

Falling air pressure, weather is usually getting worse, with the risk of storm. Fish responds to this with increased motion and eating activity. Once the decreasing barometer reaches it's lowest level, the weather is rainy and stormy. Fish activity subsided and then decrease as being the stormy weather proceeds.
