There are many variables that determine why fish are in one place one day and not the next. Hilton’s is continually seeking new data portals to provide the most information available in order to achieve the highest success ratios when fishing offshore. Hilton’s recently-launched SALINITY data portal provides “cloud free” imagery in addition to the ability to tweak the imagery to “focus” the data in the area you are interested in (similar to how you can tweak the sea surface temperatures).
This shows a 6 PSU unit range differential (30.5 to 36.5).
The latest salinity shot of the Costa Rica/Panama region—interesting to see that the Caribbean side is so much more saline than the Pacific.
Using the Adjust Tool on right side of screen, the second shot shows it tweaked down to a 3.5 PSU unit range (31.5 to 35.0), thus sharpening the data. The second shot also shows the option of removing the icon names but leaving the icons there for reference – this allows you to view the imagery unobstructed by text.
The mixed salinity looks to run along the CR coast inshore and centered off of Los Suenos – LOTS of proven fishing spots in there and also indicative of current flow NW inside of that plume.
A shot of the Gulf of Mexico between the Mississippi Delta and the Florida panhandle.
It’s interesting to see how higher salinity water comes all the way to the beach off of Panama City/Destin area but cuts off drastically before getting to Pensacola/Orange Beach which is being impacted by the freshwater coming out of the Mississippi River.
Bottom line: Salinity may be one of the deciding factors as to why fish are on a spot on that day and not the next.
