Keys Water Hits 78°F as Tarpon Season Peaks and Snapper Rules Expand
NOAA buoy 41114 recorded 78°F water and 2.3-foot seas in late April, conditions that signal prime season across the Florida Keys flats and offshore grounds. Tarpon are the headline act — upper-70s surface temps are textbook staging water for migratory silver kings stacking up on Atlantic-side flats this time of year. Salt Strong notes that the hunt for 40-plus-inch snook remains a compelling inshore target for backcountry anglers, a solid secondary option while the tarpon bite builds. Offshore, Saltwater Sportsman and Sport Fishing Mag both report a meaningful regulatory development: expanded red snapper seasons have been approved for Florida's South Atlantic waters under federal exempted fishing permits, adding a strong food-fishing incentive to offshore runs. With the moon in a waning gibbous phase and easing toward new, incoming-tide windows on the flats should produce dependably over the next several days.

What's Next
Over the next two to three days, the waning gibbous moon continues sliding toward the new moon, tightening tidal swings and shifting the advantage toward sight-fishing during low-light, incoming-tide windows. Tarpon hunters should time dawn and early-morning incoming pushes — fish will be moving onto the flats to feed, and visibility will be workable without the midday glare that sends spooky fish down. Large live mullet or dark-colored streamers on an 11- or 12-weight outfit are the classic approach; keep casts long, presentations quiet, and engines off well before the flat.
Permit and bonefish will follow similar tide logic. Crab patterns and weighted shrimp flies on 9-weight outfits should draw strikes along the edges of turtle-grass flats on the push in. Plan to be off exposed flats by early afternoon as heat builds and fish push into deeper basin edges or channel cuts — those transition zones can hold permit and larger mutton snapper in the 10-to-30-foot range during midday heat.
Offshore, the snapper opportunity flagged by Saltwater Sportsman and Sport Fishing Mag is worth planning around, but anglers should confirm current bag limits and the exact date window for Florida's exempted fishing permit season before leaving the dock — the pilot-program structure means reporting requirements and season segments differ from standard federal rules. With buoy 41114 showing 2.3-foot seas in late April, offshore access in the 20-to-40-mile corridor should be manageable on calm mornings; watch for afternoon sea-breeze build that can make the return run uncomfortable. Mahi-mahi are a natural bonus target on offshore weed lines, and the pitch-baiting technique covered by Saltwater Sportsman — keeping a live bait ready to pitch to fish that pop up behind the spread — is especially effective when dolphinfish surface behind teasers.
As the moon approaches new, expect water movement on the flats to mellow slightly, concentrating bait in channel edges and current breaks inside the reef — mark those zones for permit and snapper in the days ahead.
Context
Early May is historically the apex of tarpon season in the Florida Keys. Water temperatures in the upper 70s are exactly what drives the annual migration of Atlantic tarpon into classic staging flats, and buoy 41114's late-April reading of 78°F puts conditions squarely on schedule — neither early nor late, just solidly in the peak window. A typical peak-season Keys flat in May can hold rolling pods of fish in loose strings, making this one of the most sought-after windows in saltwater fly fishing anywhere in the world. The waning gibbous moon phase is generally considered favorable for flats work: enough ambient light to spot fish at first light, with tidal movement that keeps bonefish and permit actively feeding on the incoming.
The red snapper regulatory story is historically significant context for offshore Keys anglers. Federal closures have long frustrated South Atlantic fishermen accustomed to Gulf anglers having comparatively generous seasons. The exempted fishing permit pilot programs now approved — reported by both Saltwater Sportsman and Sport Fishing Mag — mirror the data-collection process that eventually gave Gulf states expanded state-management authority. Whether this leads to long-term structural change will depend on how the 2026 pilot data is received, but for this season it represents a genuine new option for offshore trips.
No direct charter captain logs or tackle-shop reports from the Keys were available in this reporting cycle. Species bite quality and timing recommendations are grounded in the environmental reading from buoy 41114 and established seasonal patterns for the region. Anglers should verify real-time conditions with local guides or marinas before their trip.
