Mutton Snapper and Tarpon Headline a Stacked May Bite in the Keys

What's Biting

What's Next

Over the next two to three days, the trade-wind pattern holding at Sombrero Key (SMKF1) and Sand Key (SANF1) — winds in the 15–17 knot range — is typical for mid-May and will keep the Atlantic reef edge choppy by afternoon. Plan offshore runs early, before afternoon thermal and sea-breeze effects layer on top of the trades. Buoy 41114 logged 2.3-foot seas in late April under similar conditions; expect comparable chop or slightly more on the Atlantic side this week, with the Gulf backcountry remaining more protected.

The New Moon creates strong tidal movement through backcountry passes and oceanside channels — exactly the current window that tarpon capitalize on. Dawn and early-morning flood tides are the prime sessions for sight-fishing the flats and working bridges and channel edges with live crabs or large mullet. Captain Rick Murphy's current Florida Insider report flags big tarpon action across the state, and if winds drop below 12 knots on any morning this week, conditions will be exceptional for pole-and-push flats fishing.

On the reef, mutton snapper fishing should remain productive through the end of May, though the peak aggregation tied to the full moon — now roughly two weeks past — is transitioning into a dispersal phase. The aggregation sites on outer reef structure in 150–220 ft are still worth targeting with live bait and bottom rigs, and ALL IN Key West continues to log consistent mutton catches. Yellowtail action on shallower patch reefs should hold strong regardless of moon phase; the South Florida Fishing Channel has documented solid patch reef catches at Key Largo using GULP baits as a consistent producer on this structure.

Looking toward early June, the next full moon could trigger a second mutton snapper spawn aggregation — historically one of the best windows of the year for big muttons on the outer reef. Now is a good time to scout structure.

Offshore, the Gulf side remains the high-production option when Atlantic conditions are rough. ALL IN Key West has been running Gulf trips producing cobia, grouper, snapper, barracuda, and kingfish consistently, with live bait outperforming cut bait for the larger pelagics. Watch for mahi along offshore color breaks — mid-May is when Gulf Stream-pushed blue water often presses closest to the reef and weed lines begin forming. Frigate birds and temperature breaks on the chartplotter are your best locators.

Context

Mid-May is historically one of the Florida Keys' most prolific fishing periods, stacking multiple premium fisheries simultaneously. The mutton snapper spawn — anchored to the May full moon — draws charter captains and serious anglers from across the country to well-known outer reef structure. ALL IN Key West's reporting of mutton snappers 'chewing like crazy' is precisely what the Keys fishing community expects this month. With the full moon occurring in early May, we are now in the post-spawn dispersal phase; the next aggregation cycle will set up around the June full moon, giving dedicated snapper anglers two bites at the apple this season.

Tarpon migration timing is similarly on schedule. The spring run peaks April through June as fish move northward from wintering grounds, with the Florida Keys serving as a primary staging corridor. Captain Rick Murphy's current report of big tarpon action statewide aligns with historical norms — this is exactly when these fish should be moving through. Water temperature of 78°F recorded by buoy 41114 in late April is typical for the region at that point in the season; mid-May flats and reef temps generally run 80–84°F, well within the range that activates permit, bonefish, and drives tarpon onto shallow flats in earnest.

One regulatory development with historical significance: CCA Florida and Saltwater Sportsman both report that Florida received federal approval for an Exempted Fishing Permit for Atlantic red snapper in 2026, opening a significantly expanded recreational season on the South Atlantic coast. While this primarily applies to the Atlantic side rather than the Gulf-side snapper fisheries the Keys typically targets, it represents a meaningful shift after years of severely restricted access and signals growing state management authority. Check current FWC regulations carefully before targeting any snapper species — pilot program rules can change mid-season and bag limits vary by zone. Overall, the current Keys bite is tracking right on schedule for what mid-May historically delivers: an exceptional multi-species window across flats, reef, and offshore.
