What this window means
Blackfin Tuna Season marks the mid-November through April stretch that Key West sources consistently point to as the stronger offshore tuna window. It gives anglers a useful winter and spring planning cue without tying the fishery to a single moon phase.
How to plan around it
Use this window to compare captains on range, sea-state tolerance, and whether the trip is truly tuna-forward or more of a mixed offshore plan. The best fit depends on whether your crew wants flexibility or a more specific target list.
