Phase-by-phase

Pre-Spawn

Trophy fishing window
75–77°F

Pre-spawn tarpon form daisy-chaining and rolling schools in passes, beach corners, and deep flats as water temperatures climb into upper 70s.

Daisy-chaining tarpon are visually iconic — sight-cast crab patterns and live mullet to schools. May–June pass and beach fishing peaks.

Spawn

Conservation window
77–88°F (peak 79–84°F)

Active spawning behavior. Broadcast spawners offshore. Adults form pre-spawn aggregations inshore where they are accessible to anglers.

Florida and most Atlantic states require a tarpon tag ($50+) to harvest a tarpon — typically used only for IGFA record certification. Effectively catch-and-release across the US range. Adult tarpon ma

Conservation context

Florida and most Atlantic states require a tarpon tag ($50+) to harvest a tarpon — typically used only for IGFA record certification. Effectively catch-and-release across the US range. Adult tarpon may live 50+ years.

Post-Spawn

Recovery feeding
88–96°F (~21 days)

Post-spawn tarpon disperse from spawning aggregations; resident fish continue feeding on pass mullet runs through summer.

Mid-summer tarpon fishing in passes and backcountry continues productive after spawn peak.

Summer Pattern

Standard patterns
Above 96°F

Fish disperse to summer habitat and feeding patterns. Spawn cycle complete until following year.

Standard summer fishing tactics apply.
