Every day we analyze satellite sea surface temperature imagery, chlorophyll and bait productivity data, surface current charts, and live NOAA marine forecasts to produce this report. The goal is to give you the clearest possible picture of what’s happening on the water before you book a trip or leave the dock.
Conditions move fast in the Keys. Currents shift, bait schools move, and thermal breaks appear and disappear overnight. A report from two days ago isn’t worth much. We try to update this report daily to make sure you have the most up to date info.

How to read this report
- Sea surface temperature (SST): Warmer water along the reef corridor (76–80°F) keeps reef fish active and feeding. Cold intrusions from the Gulf side can slow shallow-water species like tarpon early in the morning.
- Chlorophyll / bait productivity: High chlorophyll readings along the reef line mean bait is stacked. This often means yellowtail, mangrove snapper, cobia and others are close behind.
- Surface currents: Moderate Gulf Stream flow past the 408 Hump and Marathon West Hump creates ideal conditions for mahi, blackfin tuna, and wahoo. Slack current along the reef is better for anchoring and chumming.
- Wind and seas: Under 15 knots and seas under 3 feet puts all our trips in play. Anything above that and we focus on protected reef and backcountry options.

Overview
Marathon Fishing Prediction — Wednesday, June 10, 2026
Overall Fishing Grade: 75/100 (Good)
A strong early reef bite on a sharp color edge — but the clock matters: light dawn winds and a stacked morning window give way to a building afternoon breeze and isolated storms.
Conditions Snapshot (peak hours 6 AM – 6 PM EDT)
- Sunrise 6:31 AM / Sunset 8:13 PM
- Wind: ESE/E light early, 4–9 kt; building to E/ESE 10–15 kt by afternoon
- Seas: 1 ft or less early; 1–2 ft and choppy by mid-afternoon
- Water temp: reef line 83–84°F; Gulf-side/backcountry warm 85–86°F; a cooler band 80–82°F sits offshore in the Straits
- Tides (Vaca Cut): Low 2:25 AM (0.4 ft) · High 9:09 AM (0.8 ft) · Low 3:32 PM (0.1 ft) — weak neap range, under a foot
- Moon: waning crescent ~30% · moonrise ~2 AM · moonset mid-afternoon
- Solunar: AM Major ~8:00–10:00 AM (best — overlaps the morning high and the post-dawn feed); PM Major ~8:25–10:25 PM; Minors ~2:20–3:20 AM and ~2:50–3:50 PM
- Barometer: ~30.09 in, steady to slightly rising (stable high)
- Sky: partly to mostly cloudy, isolated afternoon showers/thunderstorms
Why This Grade
The story tomorrow is a tight color edge sitting right on the reef line — productive green water inshore breaking sharply to clean blue within a few miles, with bait pinned on the seam and warm 83–84° water on the reef. Stack that against light dawn winds and a morning bite window that lines up the high tide, the solunar major, and first light, and the early reef bite is the clear strength of the day.
Two things keep it a Good rather than a great: the tide is a weak neap (range under a foot), so the bite-driving water movement is modest and compressed into the moving-water windows; and the afternoon brings a building ESE sea breeze with isolated storms that will texture the water and close the early door. Offshore, the Gulf Stream edge is a reachable run about 14 miles south with a warm push pressing on the break — but a cooler band of water sits between the reef and the edge, and you’ll want to run past it to the cleaner, warmer side. The backcountry is warm and stable with no cool-water push to shut it down, but the soft tide means timing beats spot-hopping. Bottom line: start early, ride the morning window, and beat the breeze.
Zone-by-Zone Game Plan
- Reef & Structure (Hawk Channel patches out to the reef line, ~20–90 ft): The strength of the day. The color break sits right on the reef with clean blue just beyond — bait holds on the seam. Chum the reef line for yellowtail, work the structure edges for mangroves and muttons, and drop the deeper ledges for grouper (open season). Get the productive drifts in before the afternoon chop builds.
- Backcountry & Bridges: Warm, stable water — no cool push. Tarpon are holding on the bridges and channels and snook sit in the structure shadows (release only this time of year). The neap tide is soft, so fish live bait on the moving water — the morning incoming to the high, and the long midday outgoing — rather than the slack.
- Offshore: The edge is a reachable run about 14 miles south, with a warm push on the break and clean blue beyond the reef seam. Run past the cooler band first. Blackfin are the first-light shot on the humps; mahi and wahoo are a run-and-look on the weedlines, color changes, and the current edge. The light morning makes the ride out comfortable — go early.
Recent Local Catch Signal
Light this window. A few consistent reef reports (yellowtail and mangrove) line up with the season, but verifiable offshore chatter is thin. With limited crowd signal, this forecast leans more heavily on conditions and the water read than on recent reports.
Species Forecast — all 13, highest to lowest
| Species | Score | Technique | Location | Notes |
|---|---|---|---|---|
| Yellowtail Snapper | 80 | Chum slick, light fluoro leader | Reef line, 30–70 ft | Tight color break keeps bait pinned — long, light leaders in the slick earn more as the morning water moves. |
| Mangrove Snapper | 73 | Live/cut bait on structure | Reef & patches, 20–60 ft | Warm water has them on the structure edges — better on the early moving water before the breeze stands the chop up. |
| Tarpon | 68 | Live bait, moving water | Bridges, channels, backcountry | Bridges and channels are holding, but the neap tide is soft — work the morning incoming and the long midday outgoing, not the slack. |
| Mahi-mahi | 65 | Troll/run weedlines & color | Offshore edge, ~14+ mi | Reachable edge with a warm push — run past the cooler offshore band and work weedlines and color changes in the clean blue. |
| Grouper (OPEN!) | 63 | Drop deeper structure/ledges | Reef edges & wrecks, 60–120 ft | Open season and fishable structure — lean on the moving-water windows and drop on the deeper edges. |
| Mutton Snapper | 60 | Long leader, deeper structure | Reef edges, 50–90 ft | Tide-dependent and the range is light — time the deeper structure to the morning high and the outgoing. |
| King/Spanish Mackerel | 56 | Fast troll, flashy jigs | Nearshore & bridge edges | Watch for the flash on the moving water early; a fast troll or flashy jig draws the strike before the breeze builds. |
| Blackfin Tuna | 55 | Small feathers, live bait | Offshore humps | First-light shot while the wind is down — small trolled feathers and live bait on the edge current. |
| Snook | 54 | Live bait around structure | Bridge & dock shadows (release only) | Around bridge and structure shadows on the moving water — a release-only fishery now, so handle and revive quickly. |
| Permit | 50 | Crab on wrecks/edges | Wrecks & channel edges | The light tide softens the flats — better odds on the wrecks and channel edges than tailing fish on a slow flat. |
| Wahoo | 45 | High-speed troll | Offshore edge | A bonus on the edge — high-speed troll the break early; not the day’s main event. |
| Bonefish | 44 | Sight-fish, shrimp/fly | Flats (release only) | Cloud cuts the sight-window and the tide is weak — early, before the breeze textures the flat, is the call. |
| Sailfish | 40 | Slow-troll/kite baits | Offshore edge | Seasonal low — an incidental on the troll, not a target this time of year. |
Best Bite Windows (6 AM – 6 PM focus)
- 6:00–8:00 AM — Dawn: first light, light winds, water building toward the morning high. Top early window.
- 8:00–10:00 AM — The day’s best: solunar major overlapping the 9:09 AM high tide and the post-dawn feed.
- 10:30 AM–1:30 PM — Long outgoing keeps water moving; breeze building, so fish the cleaner morning side of it.
- 2:50–3:50 PM — Secondary solunar minor; watch the afternoon storm and chop risk.
Safety & Notes
- No Small Craft Advisory in effect. Light and comfortable early; expect a building ESE breeze and isolated afternoon thunderstorms — keep an eye on the radar and plan to be off the water or close to home by mid-afternoon.

What to Expect When Fishing in Marathon, FL
Marathon sits at the heart of the Florida Keys, with easy access to the Atlantic reef tract to the south and Florida Bay to the north. That geography gives anglers access to three completely different fisheries within a short run of the dock. Try offshore bluewater, nearshore reef and wreck, and shallow backcountry flats.
Offshore fishing
The Gulf Stream runs close to the Keys year-round, pushing warm, clean bluewater within 15–20 miles of Marathon. Offshore structure like the 408 Hump and Marathon West Hump concentrate baitfish and attract pelagics in numbers that few places on the East Coast can match. Mahi-mahi are the bread-and-butter species spring through summer, with blackfin tuna and wahoo filling the box on the right day.
Reef and wreck fishing
The Florida Keys reef tract is one of the most productive fishing grounds in North America. Yellowtail snapper and mangrove snapper are on the reef virtually every day of the year. Mutton snapper and cobia show up in numbers during spring. Expect action from grouper (when in season), amberjack, cero mackerel, and barracuda.
Backcountry and flats fishing
Florida Bay and the grass flats north of Marathon are some of the best tarpon and bonefish water in the world. Tarpon migrate through the Keys from April through July in serious numbers. Permit, snook, and redfish round out the backcountry offering.
Seasonal fishing guide for Marathon, FL
- Winter (Dec–Feb): Yellowtail and mangrove snapper fire up in cooler water. Sailfish peak offshore. Calm weather windows make for excellent bottom fishing days.
- Spring (Mar–May): The best all-around season. Mahi arrive in force by March. Cobia move through the reef. Tarpon migration kicks off in April.
- Summer (Jun–Aug): Mahi, tuna, and wahoo offshore. Consistent reef fishing. Morning trips are the move before afternoon thunderstorms build.
- Fall (Sep–Nov): Kingfish move in. Reef fishing stays strong. Cooler temps and lighter crowds make fall an underrated time to fish the Keys.
Bait, tackle, and trip planning
Our Marathon bait and tackle shop carries fresh, live, and frozen bait along with everything you need for a day on the water. For a fully guided experience, our Marathon fishing charters cover all three fisheries. Also fishing out of Big Pine Key if that puts you closer to the action.
