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.

Upcoming Fishing Conditions
11/4/2026
Overall Fishing Grade
65/100 (Good) — The flattest water of the stretch arrives on the weakest tide of the cycle, so the whole day funnels into one morning window. A light east-to-northeast breeze of 5 to 10 knots lays Hawk Channel down to 1 to 2 feet and smooths the Straits off Marathon to the same, the calmest it has been in over a week, but the moon is riding its declination floor and the daytime tide range has collapsed to about a third of a foot — one soft morning flood into a 10 AM high and not much else. The reef still leads, with yellowtail, a fresh limit of open-season grouper and mangrove anchoring a real bottom day, and the flat seas and a current building past 2 knots over the humps make the offshore run worth a look even though the fresh offshore catch proof has gone quiet. Be on the reef line at first light, fish the building morning flood hard, and keep half an eye on the sky.
Conditions Snapshot (peak window 6 AM–6 PM EST)
- Sunrise is 6:33 AM and sunset 5:42 PM — the clocks fell back Sunday, so daylight runs early and the dark closes fast after five.
- East-to-northeast winds are light at 5 to 10 knots through the morning, freshening only toward 10 late in the afternoon, laying a light 1-to-2-foot chop in Hawk Channel and a gentle 1-to-2-foot sea off Marathon that subsides toward a foot — the calmest water of the past week.
- Reef-line water is holding near 82 degrees with the backcountry a touch cooler near 80, and the offshore water is a uniform 82 to 83 with no temperature break inside 30 miles; the barometer is steady near 30.00 inches under broad high pressure with no frontal signal, and the sky is partly sunny with a slight chance of a passing shower or thunderstorm.
- The moon is a thin waning crescent, only about 20 percent lit and still thinning toward the new moon late next week — it rises near 2:15 AM, transits around 8:35 AM and sets near 2:50 PM.
- Tides at Vaca Cut run a low of 0.8 feet at 1:42 AM, a high of 1.1 feet at 10:00 AM, a second low of 0.8 feet at 2:12 PM, and a high of 1.1 feet at 11:06 PM — a very soft daytime range of only about a third of a foot, the weakest of the cycle, with the moon sitting at its declination floor.
- The one real piece of moving water in daylight is the morning flood building from first light into the 10 AM high; the midday ebb is weak and the afternoon rise is slow.
- The solunar major lands in the morning, roughly 7:35 to 9:35 AM, stacked right on that building flood, with a minor near 2:20 to 3:20 PM at moonset by the early-afternoon low; the evening major comes after dark.
- Take-home: be anchored on the reef line at first light and fish the morning flood — that is the day’s water.
Why This Grade
This is still a good day, and a fishable one, but it is a notch below the start of the week, and the reason is a split decision between the two best things going and the one thing working against them. In favor: the seas are the flattest they have been in over a week, and the reef has genuine fresh proof behind it. Against: the tide range has collapsed to about a third of a foot on a thin, weakening moon, so the moving water that drives every bite is soft and short, concentrated almost entirely into the morning flood. The grade leans on the day’s strongest realistic, accessible, in-season opportunity — the snapper and bottom bite on the reef line — holds it up on the calm seas and the catch signal, and trims it back for the weak tide and a passing-shower chance.
On the reef, the pieces mostly line up. Water is holding near 82 degrees, the fall chumming pattern is on, and with the breeze down to 5 to 10 knots and Hawk Channel at 1 to 2 feet, anchoring and holding a slick over hard bottom is as easy as it has been all week. The reef-line current is soft, under half a knot, which makes anchoring easy but means the slick leans on the tide rather than the current. The catch is there too: yellowtail came off the reef on a recent local trip, a limit of open-season black grouper came off the bottom on another, and mangrove rounded out a third. The catch, not the clock, is what keeps the reef on top. The one honest caveat is the tide — the soft, third-of-a-foot range means the slick stretches best on the morning flood and goes slack and lazy by midday, so the front half of the day carries most of the weight. Yellowtail lead, with mangrove tight to the patches and a genuine shot at open-season grouper on the ledges while the seas are flat enough to sit over structure.
Offshore is finally an easy run rather than a capable-boat-only call, and the water has a little more going for it than the catch signal suggests. The Straits off Marathon are down to 1 to 2 feet, so the humps 20-plus miles out are well within reach, and the offshore current is building — close to 2 knots about 18 miles out and past 2 knots by 24 miles — which is the kind of push that stacks bait on the up-current face of the humps and the drop. Blackfin and the first sailfish of the transition are the seasonal plays out there. What still holds it back is the catch signal: the fresh offshore proof that carried the pelagics earlier in the week could not be re-confirmed this morning, so the humps are scored on season, access and current rather than a live report — a reasonable run, not a sure thing. The Gulf Stream edge still sits a long way out, roughly 31 miles southeast, and the offshore water is a uniform 82 to 83 degrees with no temperature break inside 30 miles, so the pelagic play is structure and current — the humps and the drop — rather than a color line.
The backcountry is still the day’s soft spot, though the lighter breeze helps a little. A 5-to-10-knot breeze is easier on the flats than the week has been, but passing clouds and the weakest tide of the cycle still work against sight-fishing the open flats, and the flats species have no catch signal behind them. The play there is moving water in the shelter — leeward bridge shadows and protected mangrove edges on the morning flood — rather than poling a bright open flat. Snook and tarpon are the realistic backcountry shots on the moving water; permit and bonefish stay narrow until the tide rebuilds later in the week, with the calmer morning the best of their window.
The caution that keeps this in the mid-60s rather than higher: the tide is soft and short, and the sky is not guaranteed. The one-third-of-a-foot range moves water with no real push, so timing the morning flood matters more than usual, and a passing shower or thunderstorm can shut a morning down in minutes. Neither is a reason to stay home on the calmest, most catch-backed day of the week — it is a reason to start at first light and let the morning flood do the work before the water goes slack.
Zone-by-Zone Game Plan
- Reef & Structure (30–120 ft): This is the heart of the day. Chum the reef line on the building morning flood and keep the slick tight — the light wind, flat seas and soft reef current make anchoring and holding easy, but the weak tide means the front half of the morning carries the bite. Yellowtail first, with mangrove on the patches and shallower structure, and mutton leaning to the cleaner, deeper edges as the sun climbs. Open-season grouper are a genuine target while the seas are flat enough to sit over the ledges and wrecks — a limit of black grouper came off the bottom on a recent local trip, so a bridled live bait on hard bottom is worth the drop. Light fluorocarbon leaders earn more bites once the morning sun is up.
- Offshore (18–31 mi to the edge): An easy run with the Straits off Marathon down to 1 to 2 feet. Water is a uniform 82 to 83 degrees with no temperature break inside 30 miles, but the current builds to around 2 knots over the humps 18 to 24 miles out, so fish structure on the up-current side — jig and live-bait the humps for blackfin and put kites up along the drop for a transition-season sailfish. The fresh offshore catch proof went quiet this morning, so treat it as a reasonable seasonal run rather than a sure bite, and watch the radar for building cells with the early dark in mind.
- Backcountry & Bridges: A lee-side, moving-water game. The lighter breeze helps, but passing clouds and the weak midday tide keep the open flats off the top of the plan, so work the leeward bridge shadows and protected mangrove edges on the morning flood. Snook and tarpon are the realistic shots; permit and bonefish stay long odds until the tide builds, with the calm early morning the best of their window.
Recent Local Catch Signal
Light to moderate (reef-only)
The read is honest and narrow: everything fresh in the last few days has come off the reef. Recent local trips produced yellowtail snapper, a limit of open-season black grouper, and mangrove snapper on the reef line — the reason those three sit at the top of the board. The offshore blackfin that showed earlier in the week could not be re-confirmed this morning, so the pelagics have no live catch backing today and are scored on season and conditions. Every other species went unseen in the window, which reflects limited visibility rather than a slow bite; they are scored on season, structure and conditions, not called slow. Reef snapper and open-season grouper are what the water is actually giving up right now.
Species Forecast
| Species | Score | Technique | Location | Notes |
|---|---|---|---|---|
| Yellowtail snapper | 70 | Light chum, long fluoro leaders | Reef line 30–90 ft | The clearest catch signal on the board and the prime November target; the flat seas and soft reef current make the reef easy to work, so lean on the building morning flood before the weak tide goes slack by midday. |
| Grouper (OPEN!) | 64 | Bridle a live bait on hard bottom | Ledges & wrecks 60–120 ft | Black and red open through December 31, and a limit of black grouper came off the bottom on a recent local trip; the flat seas make it easy to sit over structure, so the better window is early while the morning flood still pushes water over the ledges. |
| Mangrove snapper | 62 | Live bait tight to structure | Patches & bridges 20–60 ft | Catch-backed on the reef this week; holds close to the hard stuff, and the lighter morning flood is where the gentle current keeps them honest before it fades. |
| Mutton snapper | 59 | Live bait or jig on the bottom | Reef edges & deeper patches 40–90 ft | Work the ledges on the morning flood; muttons want moving water, so the soft midday tide trims their window — the cleaner, deeper edges are the better bet as the sun climbs. |
| Blackfin tuna | 59 | Jig or live bait on the humps | Offshore humps 18–25 mi | The flat Straits make the run easy and the current building toward 2 knots over the humps gives them something to set up on, but the fresh offshore proof went quiet, so lean toward the up-current face early before the afternoon breeze or a cell builds. |
| King/Spanish mackerel | 55 | Wire trace, flashy bait | Nearshore & reef edges | The fall run is building and the light morning wind favors a slow troll along the reef edges, but the nearshore water is still warm for a strong king push and there is no fresh catch read yet. |
| Sailfish | 53 | Kites, live bait on the edge | Offshore current edge & drop | November’s transition is nudging fish through and the building offshore current helps, but the light east wind is softer than the north push a sail bite really wants — kite it if you make the run, with blackfin the surer target. |
| Wahoo | 51 | High-speed troll | Offshore drop & edge | A seasonal fall shot that improves as the moon heads toward dark late this week; the stronger current along the drop is a plus, but with no fresh signal it stays a second thought behind the reef. |
| Mahi-mahi | 46 | Troll weed lines & edges | Offshore weed & edge | Past the summer peak with the edge 31 miles out and no temperature break inside 30; a bycatch chance on any scattered weed rather than the plan for the day. |
| Snook (RELEASE) | 46 | Work the shadow lines | Leeward bridges & mangrove edges | The lighter breeze helps, but the soft tide and cloud keep it a lee-side play — fish the shadow lines on the morning flood, not the open shallows. |
| Tarpon (RELEASE) | 45 | Live bait in the shadows | Bridges & channels | Resident late-season fish hold in the bridge shadows and cuts; the weak tide thins the numbers, but the calm morning flood is the window for a shot. |
| Permit (RELEASE) | 43 | Crab on leeward wrecks | Wrecks & leeward flats | The weak tide and passing clouds keep a crab on a lee-side wreck the better odds than the open flats; the calm morning flood is the one real window. |
| Bonefish (RELEASE) | 40 | Sight-fish the sheltered edges | Clean leeward flats | The thinnest tide of the cycle gives poor flats movement, though the lighter early breeze helps sight-fishing — pick a sheltered flat and work the edges on the morning flood, but the odds are long today. |
Best Bite Windows
- 1) Morning flood, 6:33–10:00 AM — sunrise, the building flood into the 10:00 AM high, and the solunar major (roughly 7:35–9:35 AM) all stack on the one real piece of moving water in daylight, with the lightest wind of the day. This is the day’s prime window; be anchored on the reef line and chumming for it.
- 2) Late morning to early afternoon, 10:00 AM–2:12 PM — the ebb off the morning high is weak, so the water moves but softly; still fishable on the reef, with the better of it right after the turn, and the offshore current keeps the humps working through midday.
- 3) Midday minor, 2:20–3:20 PM — the solunar minor lands at moonset near the 2:12 PM low, a short slack-to-flood turn worth being on structure for.
- 4) Evening, 5:00–5:42 PM — the afternoon flood is building into last light, but sunset comes at 5:42 and the dark arrives fast, so this is a brief window only.
Safety & Notes
- The calmest water of the week — a light east-to-northeast breeze of 5 to 10 knots, Hawk Channel at 1 to 2 feet and the Straits off Marathon at 1 to 2 — with a slight chance of a passing shower or thunderstorm riding the easterly flow, so confirm the latest marine forecast, watch the radar, and give any building cell room.
- There is no Small Craft Advisory for the Marathon waters.
- The clocks fell back Sunday, so sunset comes at 5:42 PM and the dark arrives early — plan to be in before it.
- Reef traffic stays busy into November; keep dive flags out over the reef and give divers room.
- Normal fall sun and heat apply, so water and shade still matter even with clouds around.

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.
