Viewing Fishing Information

The weather Fishing chart shows present water temperature, present surface pressure conditions, and fishing
forecasts.
From the Home screen, select Weather > Fishing.
Surface Pressure and Water Temperature Data
Surface-pressure information appears as pressure isobars and pressure centers. Isobars
equal pressure. Pressure readings can help to determine weather and wind conditions. High-pressure areas are
generally associated with fair weather. Low-pressure areas are generally associated with clouds and the chance
of precipitation. Isobars packed closely together show a strong pressure gradient. Strong pressure gradients are
associated with areas of stronger winds.
