SuperMap Weather Data Options
Radar
In a nutshell, SuperMap Radar displays current precipitation levels across the area...just like when you see your local TV weatherman show his Radar on his screen. Lighter colors mean less precipitation. The light blue color is the lightest precipitation and the purple and white are the heaviest. For a full explanation of Weather Radars and their readings, click here:

Weather buoys
When you select Weather Buoys on SuperMap, you will see all the weather buoys display on the map. Single click on the buoy (or ship) of your choice and you will get a popup of info. Depending on scenario and amount of info available at the moment, you will see such things as the station's name, GPS location, wind direction, wind speed, wind gust, atmospheric pressure, significant wave height, dominant wave period, pressure tendency, air temperature, dew point, visibility, and water temperature.
Data from these weather buoys updates every 10 minutes.
Weather warnings
By selecting Weather Warnings feature, you will see small graphics appear in the particular warning area. For example, a yellow graphic with a lightning strike in its center hovering over Springfield reveals a current warning for severe thunderstorms there. A green graphic with water waves running through it over Jonesboro, Arkansas means a flash flood warning has been issued there. Single click on the graphic and a popup will display which gives full information on the National Weather Service release. The popup will contain the area affected, times, warning type, and vital information that will help keep your family safe.
Wind
Select the Wind feature under SuperMap's Current Weather. You will see graphics appear over the water. These show you the directions of the wind. On the bottoms of each, you will notice lines attached that make them almost look like flags. These show wind speed: 1/2 line = 5 knots, 1 line = 10 knots, 2 lines = 20 knots. Any that appear darker than the others just means that there are 2 overlapping each other.
Barometric pressure
When current Barometric Pressure is selected, your map will display lines of barometric pressure readings. Barometric pressure is the measure of the weight of the atmosphere above us. It exerts pressure on the waters we fish and even on us. Areas with high pressure are the areas with good weather, and the areas with low pressure are the areas with bad weather. As a general guideline, think of 30 inHg (1016 millibar) as being a normal level. World records vary from a high pressure of 32.0 inHg in Siberia to 25.7 inHg during a typhoon. For the US, extreme levels can be considered as 30.5 inHg and 28.5 inHg. When it comes to fishing, a change of just +/- 0.02 inHg from normal is enough to effect their feeding habits. Take a look at this chart also from an article on "The Effects of Barometric Pressure on Fishing" by Lee Adams:
High Pressure = Clear Skies = Fish slow down, find cover or go to deeper waters = Slow down lures and use baits more attractive to fish, fish in cover and in deeper waters.
Rising Pressure = Clearing of Improving conditions = Fish tend to become slightly more active = Fish with brighter lures or near cover, also fish at intermediate and deeper depths
Normal and Stable Pressure = Fair = Normal Fishing = Experiment with your favorite baits and lures
Falling Pressure = Degrading = Most active fishing = Speed up lures, surface and shallow running lures may work well
Slightly Lower = Usually cloudy = Many fish will head away from cover and seek shallower waters, some fish will become more aggressive = Use shallow running lures at a moderate speed
Low Pressure = Rainy and Stormy = Fish will tend to become less active the longer this period remains = As the action subsides, try fishing at deeper depths.
NOTE: It is important to know that barometric pressure is just one of many factors that effect fish feeding habits.
On the contrary, Dr. David A Ross, scientist emeritus at the Woods Hole Oceanographic Institution and the author of The Fisherman's Ocean, states that Barometirc Pressure has no effect on fishing. You can read his article HERE.
So, I'll leave it up to you to decide if this affects Fishing.  |
