Use SST imagery to find 75–80°F water adjacent to a temperature break of at least 2°F. Run weed lines and color changes. Look for birds working bait above the surface — mahi push bait up.
Verify with current SST imagery
These ranges are climatological norms. Actual SST varies year over year — get an SST satellite shot the day before you run.
