Q.SST & Offshore Fishing
What water temperature do mahi-mahi prefer?
A.
Mahi-mahi prefer water temperatures of 75-82°F, with peak activity in the 78-80°F range. They tolerate down to about 70°F and up to 86°F but feeding shuts down outside the core range. Find a temperature break where 78°F water meets 75°F water and mahi will be there.
Look for floating debris, weed lines, and color changes within the preferred SST band. Frigatebirds working over the water often mark mahi feeding below. SST threshold pages cover the species-specific temperature ranges; migration calendar pages cover seasonal availability.
