Bluewater IQ is a predictive fishing map for the Pacific coast of Nicaragua and Guanacaste, Costa Rica.
It pulls the ocean and weather data that moves fish — sea-surface temperature, thermal fronts, bathymetry, currents, wind, tide and sun — and turns it into a heat map of where conditions look best today, for the species you're after.
CHOOSE YOUR HOME PORT
Tell the app where you launch and everything measures from there: the range rings, the run home, daylight left, bite times, and the range cost behind every mark.
WHAT IT SHOWS
• A daily heat map, per species. Sailfish, yellowfin, mahi, wahoo, roosterfish, cubera, marlin, snook, mackerel and spearfishing each have their own depth, temperature and structure preferences, so each gets its own map, not one map with a filter.
• Temperature breaks. The sharpest sea-surface temperature gradients in today's field, drawn as lines. These are the edges bait stacks on.
• Live conditions. SST and its range, wind and sea state, thermocline depth, moon phase, season, and the state of the Costa Rica Thermal Dome and Papagayo upwelling.
• Tides and bite times. Today's turns, the current stage, and solunar windows.
• A three-day wind forecast, as a go / marginal / no-go strip against a 10-mile departure gate, blended from several models so you can see where they disagree.
• Surface currents, ocean colour, range rings, the maritime boundary and the local fishing marks.
ON THE WATER
• Record your track by GPS, screen locked, and export as GPX, KML or GeoJSON.
• Log a catch from a photo. The catch is placed from the photo's own location data and nothing else, so every mark is where the fish actually was. Shoot with the Camera app and location on; forwarded photos arrive stripped and are refused rather than guessed at. The sea temperature and nearest mark at that spot are recorded with it.
• Helm tools: anchor-drag alarm, range and bearing home, daylight remaining, and a trip timer.
• Drop waypoints, and scrub back through archived days.
WHERE THE DATA COMES FROM
Public sources: NOAA for sea-surface temperature and marine forecasts, Open-Meteo for wind, tide and current models. Conditions refresh daily and the app always shows the date of the data you are looking at. Your last download stays available offline.
HONEST ABOUT WHAT IT IS
The heat map is a model, not a fish finder. It ranks relative likelihood from conditions and has not been calibrated against catch records. It narrows down where to look; it will not tell you there are fish there.
Bluewater IQ is NOT a navigation aid. Do not use it for piloting, collision avoidance, or in place of official charts and forecasts. Depths are model-derived, not surveyed soundings. Carry proper navigation equipment and check official forecasts before you leave the dock.
Coverage is nine ports between Puerto Sandino, Nicaragua and Tamarindo, Costa Rica, out to roughly 80 miles offshore. Ports further south in Costa Rica are not mapped yet, and the app says so rather than showing an empty map.
Your tracks, catches and photos stay on your device.
