A: Fish are sensitive to pressure changes. Falling pressure (before a storm) often makes fish more active and likely to feed. Rising pressure (after a storm) can slow feeding. The best fishing typically occurs when pressure is between 29.70-30.40 inches and stable or slowly falling.
A: The ideal barometric pressure for fishing is between 29.70 and 30.40 inches of mercury (1006-1030 millibars). Fish tend to be most active when pressure is stable or slowly dropping. Rapid changes in either direction can make fishing more challenging.
A: Yes! The Thermometer app includes a fishing forecast feature that analyzes barometric pressure trends and predicts optimal fishing times. It rates fishing conditions from poor to excellent based on pressure patterns, moon phase, and weather conditions.
