Viewing Fishing Information

The weather Fishing chart shows present water temperature, present surface pressure conditions, and shing

forecasts.

From the Home screen, select  > .

Surface Pressure and Water Temperature Data

Surface-pressure information appears as pressure isobars and pressure centers. Isobars

➊

connect points of

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.

➊

➋

Pressure units are shown in millibars (mb), inches of Mercury (inHg), or hectopascals (hPa).

Colored shading, as dened by the legend

➋

in the upper-left corner of the display, indicates the surface temperature

of the water.
