Bahamas & Nassau chlorophyll chart
Satellite data from
The central Bahamas — Nassau, Andros, the Berry Islands, Eleuthera, the northern Exumas and Cat Island — with the deep water of the Tongue of the Ocean, Exuma Sound and the Providence Channels cutting between the banks.
How to read today’s The Bahamas chart
Work the colour line. Green water is productive and blue water is clean; bait stacks on the seam between them, and gamefish hunt that seam. The contours above trace the productivity edges so the line is something you can put a waypoint on.
The highest-percentage water offshore is where a chlorophyll edge lines up with a temperature break. Check this against the The Bahamas SST chart and start where they overlap.
Pair it with temperature
Chlorophyll shows you the food. Temperature shows you whether the conditions suit the fish you are after. See today’s The Bahamas SST chart →
Frequently asked
How often does the The Bahamas chlorophyll chart update?
The image is regenerated twice a day from the latest satellite chlorophyll data in the Catalysst app, rendered on a log scale and clipped to the coastline. The date shown is the date of the satellite data, which moves forward about once a day.
What area does the The Bahamas chlorophyll chart cover?
From 23.7°N to 26.3°N and 79.0°W to 75.0°W. Ports and landmarks on it include Nassau, Andros, Eleuthera, the Exumas, the Berry Islands, Cat Island, the Tongue of the Ocean and Exuma Sound.
Do you fish the green water or the blue water?
Neither — you fish the edge between them. Bait gets pushed against the clean-water line and predators hunt that seam. The highest-percentage water is where a chlorophyll edge stacks on top of a temperature break.
Why does chlorophyll matter if I already have SST?
Temperature tells you where conditions suit the predator; chlorophyll tells you where the food is. A break with no bait on it is just a line in the water.
