The spring warm-up
Spring is all about momentum. Each warm day nudges the water temperature up, and that wakes the whole system: bait pushes back onto the flats, and the gamefish that were sluggish all winter start feeding hard to make up for it. The fishing gets better week by week, which is part of what makes spring so fun — you can feel it building. We're back to running the open flats and mangrove edges of the Ten Thousand Islands hard now. For how the whole year flows, see our Naples fishing calendar.
What's biting now
Snook are the spring stars — as the water warms they get aggressive and start staging toward the passes and beaches, eager to eat a well-thrown bait or lure. Redfish fire up on the flats and oyster bars, seatrout are thick over the grass, and fast movers like jacks and Spanish mackerel blitz bait schools, which is a blast on light tackle.
| Fish | Where | Note |
|---|---|---|
| Snook | Mangroves, passes, beaches | Staging up & feeding hard |
| Redfish | Flats & oyster bars | Active and tailing on warm days |
| Spanish mackerel | Passes & nearshore | Fast, toothy, fun on light tackle |
| Tarpon | Passes, south of Marco | First scouts in late spring |
The first tarpon scouts
The moment every local waits for is the first roll of a tarpon — a silver back breaking the surface near a pass or off the beaches south of Marco in late spring. These early scouts are the leading edge of the season that peaks in summer, and hooking one of these acrobatic giants is a bucket-list thrill. Remember that tarpon are catch-and-release only — we fight them, photograph them, and send them home strong. With everything firing in spring, it's a fantastic time to book an inshore charter and ride the rising tide of the season.
From the Helm: Spring fishing off Naples: watching the water-temp swing before we commit to the Marco River flats
Spring decisions start with the thermometer more than the calendar. A run of warm, sunny days can push water temperature up several degrees in under a week, and that’s usually our cue to work the grass flats along the Marco River rather than staying tucked in the deeper backcountry we favored all winter. A late cold snap can undo that just as fast, so we’re checking overnight lows before committing to a plan, rather than assuming spring behaves the same way twice in a row.
We’re also reading bottom color as much as the thermometer. A grass flat that’s gone from a dull olive to a brighter, almost lime green usually means new growth is filling back in after winter, and that’s where bait starts stacking first. A flat that’s still patchy and brown gets skipped in favor of the greener water nearby, even if it’s only a few hundred yards away, because that’s usually the difference between a flat holding fish and one that’s still waking up.
On the flats, our captains are looking for signs that fish have shaken off winter — redfish tailing in skinny water, snook stacked tight along a mangrove edge instead of buried deep in a canal. We’ll ease in slow on the trolling motor and let guests get a look before a single cast goes out, because spring fish still spook easily even once they’ve started feeding aggressively again.
If a cold front slides through and shuts the flats down mid-season, we don’t force it. We’ll run into the canals around Isles of Capri instead, where deeper water holds heat longer and fish that vanished off the flats overnight tend to regroup there. It’s a slower, more methodical bite than the flats produce on a warm morning, but it keeps rods bent when the open water goes quiet.
The part guests don’t expect is how early the first tarpon show up, weeks before most people think tarpon season has started. It’s usually a single fish or two, rolling once near a pass mouth and gone, not the stacked-up push you’d see by early summer. Spotting one is genuinely exciting for our captains too — it’s the first real sign the season’s turning, even if it’s nothing you can build a whole trip around just yet.
That early scouting behavior is worth watching for even if tarpon aren’t your main target, because it tells us the whole system is warming up. If they are the draw for you, our tarpon fishing guide covers where that bite builds through the season. Curious which pattern you’ll land in? Our fishing charters page walks through booking, and we’ll pick the plan once we see what the water’s doing that week.
