What this window means
Mangrove Snapper Spawn is moon-focused too, but less exact than mutton. Florida Keys sources point to the period just after the June full moon and into July and August as the most useful planning stretch, with July standing out as a major spawn month.
How to plan around it
Ask whether the captain treats mangroves as the main target or as part of a mixed reef plan. The best bookings here come from clear expectations about trip length, technique, and whether the crew wants numbers, size, or a balanced day.
