Key West Natural Event
Mutton Snapper Spawn
These short late-spring and early-summer windows are intentionally tied to the strongest full-moon mutton snapper periods near Key West.

What this window means
Mutton Snapper Spawn is the clearest moon-driven fishery on this calendar. Key West operators consistently describe it as a May and June full-moon opportunity, so these windows stay intentionally tight instead of drifting into a broad summer season.
How to plan around it
If mutton snapper is the main goal, ask captains how they plan around the moon phase, current, depth, and reef structure on your dates. This is a targeted fishery where a narrow calendar window matters more than generic seasonal copy.
