Know where the fish are before you leave the dock.
A predictive fishing heat map for San Juan del Sur, Nicaragua — eleven species scored every morning from live satellite and ocean-model data, on a 60-mile map of your water.
One map, eleven ways to read the water
Sailfish don't feed where snook feed. Every species gets its own scored map — sailfish, marlin, yellowfin, mahi, wahoo, roosterfish, cubera, snook, sierra mackerel, a spearfishing layer, and a combined view when you just want the best answer.
Temperature breaks & currents
Auto-detected SST breaks — the edges bait stacks on — with live surface currents drawn over the heat, so you can see the conveyor belts.
The vertical picture
A measured thermocline with a five-day forecast, and the oxygen ceiling — how much fishable water the column actually holds today.
Departure windows
Dawn-out and afternoon-back legs rated go / marginal / no-go against a panga's real limits, three days ahead, from a multi-model wind consensus.
Tides & bite times
Tide stage and turns, solunar majors and minors, and the incoming-tide bite wired straight into the snook score.
On the water
GPS track recording, waypoints, a photo catch log, anchor-drag alarm, back-to-port bearing and daylight countdown — the safety tools are free, always.
History playback
Scrub back through archived days — SST, heat, currents and conditions — and watch how the water that produced fish set up.
See it read the water
Thirty seconds of the live app: the same morning scored for yellowfin, mahi, roosterfish and the combined view — watch the answer move offshore and back inshore as the species changes.
How it works
Satellites & models overnight
NOAA sea-surface temperature, Copernicus subsurface and altimetry, Open-Meteo wind and marine forecasts — fetched and quality-checked daily.
Your water, scored
A 60-mile grid around San Juan del Sur is scored per species: temperature preference, fronts, structure, distance, season and climate state.
