Satellite ocean data for offshore anglers

Read the water before you leave the dock.

Sea temperature, temperature breaks, water color and clarity, and the shape of the bottom, from the latest satellite passes, next to the wind, waves and tide for your trip. One screen, every morning.

Screenshot of the Fish Foresight app on Wednesday, October 14, 2026, early in the morning, showing the newest data on every map. A large map of sea surface temperature off Northeast Florida, on a scale set in the app from 78 to 86 °F, shows dark blue and blue water along the Georgia and northern Florida coast, cyan, green and yellow over the shelf, and orange to red Gulf Stream water offshore, with depth contour lines, towers and buoys, and an 80-nautical-mile range ring from St. Marys Entrance at Fernandina with the water beyond it shaded. The notes beside it say satellites saw 100% of the water in the last 24 hours. Six small maps around a fishing spot 59 nautical miles out, where the green shelf water meets the orange Gulf Stream water, show the temperature break there (0.81 °F per nautical mile), the water class (clean green), the fish opportunity score (locked: not validated yet), the depth (139 feet), chlorophyll (0.41 milligrams per cubic meter, flagged because the reading is 47 hours old) and NASA true color imagery from October 13.
The app on Wed, Oct 14, 2026, with the newest data on every map. In that morning's 6:00 am temperature map, satellites saw all of the water in the past 24 hours. On cloudy days the water they missed stays gray, and the app says how much.

Read the water

Data first: every layer worth checking, on one screen, before you run offshore.

We build these maps ourselves, pass by pass, from NASA, NOAA and European satellites and NOAA's surveys of the bottom. Each map says when its newest reading was taken and how much of the water the satellites saw. Where they saw nothing, the water stays gray instead of being filled with a guess; the one gap-filled map is labeled as gap-filled. Colors can stretch to fit the water you're looking at, or hold the month's fixed scale, or one you set, so a color means the same temperature from day to day.

Map of sea surface temperature off Northeast Florida, from Brunswick, Georgia, to south of Cape Canaveral, on Tuesday, October 13, 2026, at 6:00 am, colored on a scale set in the app from 78 °F or colder (dark blue) to 86 °F (dark red): dark blue and blue water along the Georgia and northern Florida coast, cyan, green and yellow over the shelf, and orange to red Gulf Stream water offshore, with a paler orange swirl in the north; depth contour lines, towers and buoys are drawn in.

Map of temperature break strength off Northeast Florida on Tuesday, October 13, 2026, at 6:00 am, from black (no change) through purple and orange to pale yellow (1 °F per nautical mile or more): a bright line runs the length of the map along the inshore edge of the Gulf Stream, with fainter orange and purple lines and a ring around a swirl offshore, and dark water over the shelf; gray where nothing was measured, across much of the water offshore in the south.

Temperature breaks

How fast the temperature changes across the water, measured only between readings taken at the same time, so a cloud edge or the seam between two satellite passes doesn't show up as a break.

Map of the sea floor off Northeast Florida, from Brunswick, Georgia, to south of Cape Canaveral, relief-shaded and colored by depth from red and orange in the shallows through yellow and green to blue past the shelf edge (0 to 4,000 feet and deeper): ridges cross the shelf, the steep shelf edge runs north to south with rugged deep-water relief beyond it, depth contour lines, towers and buoys are drawn in, and white outlines mark the areas NOAA surveyed in detail.

Bottom relief

NOAA's survey depth, shaded as if lit from the side so ledges, ridges and the shelf edge stand out. Areas NOAA surveyed in detail are outlined; elsewhere the depth is filled in between older soundings and smoothed.

Map of water classes off Northeast Florida from satellite passes up to Tuesday morning, October 13, 2026: dark brown dirty green water along the coast from southern Georgia to New Smyrna Beach and again near Cape Canaveral, an olive patch of green water with no red reading off Cumberland Island and Fernandina Beach, a band of teal clean green water outside the brown over the shelf, blue water offshore, and gray where clouds hid the water, over much of the offshore water.

Check our work

Every satellite hour behind the map.

The rolling map is only as good as the readings under it, so the app shows them. Step through the past day hour by hour, exactly as NOAA's hourly weather satellite measured it: no smoothing, clouds left gray, and the few small holes it left in clear water filled from other satellites' passes and outlined, so you can tell them apart.

Beside it, a second map shows how old every reading on the rolling map is.

Daytime hours are shown as measured too. Where the sun heats calm water, the surface reads warmer than the water below it, and the app says so on those hours.

Screenshot of the app on Tuesday, October 13, 2026, two maps of the water off Northeast Florida side by side. Left: sea surface temperature at 1:00 am exactly as NOAA's hourly weather satellite measured it that hour, colored on October's scale from 74 °F (dark blue) to 86 °F (dark red): cyan along the northern coast, green and yellow over the shelf, and orange to dark red Gulf Stream water offshore with a warm swirl in the north. The satellite saw 87% of the water; the rest is gray, where cloud hid it, mostly offshore in the south, and dashed outlines mark the patches filled from other satellites' passes 2 to 11 hours old: in the middle of the swirl, along the coast, over the shelf and offshore. Right: how old each reading on the 6:00 am rolling map was: bright blue, seen within 3 hours, over about two-thirds of the water, including the whole shelf, and darker blue offshore, seen 3 to 6 hours earlier, over most of the rest.

Plan the trip

The water, the weather and the tide, together.

Wind, gusts, waves, wave period, pressure and rain at your spot for up to eight days, from the National Weather Service, ECMWF and NOAA's GFS, or a composite of the three. Each day is colored from green to red against the limits you set for your boat.

Screenshot of the app's forecast table from Tuesday, October 13, to Tuesday, October 20, 2026, from the composite of the three forecasts. Tuesday through Friday are green, with winds of 2 to 9 knots, gusts up to 12, and waves of about 2 to 2.6 feet. Saturday through Monday are red, with winds of 17 to 28 knots, gusts up to 38, and waves up to 10.6 feet. Tuesday the 20th has no forecast yet. Rows below give the wave period, the period-to-wave ratio, pressure, rain chance and the moon.

Screenshot of the app's tide graph for the Vilano Public Boat Ramp near St. Augustine, from Tuesday, October 13, to Tuesday, October 20, 2026, from NOAA's Vilano Beach station: two highs and two lows a day, highs of about 4 to 5.8 feet and lows of about 1.1 to 1.8 feet above mean lower low water, with each day's leave time (4:00 am) and return time (6:00 pm) marked, and the times the water is below the 1.5 feet this ramp needs shaded.
Tide at your launch: NOAA predictions for the nearest station, with the times you leave and come back marked, and the water too low for your ramp shaded.

In testing

The opportunity score: tested before it's shown.

The score puts the layers together for one species, wahoo first, and rates the water from 0 to 100. It isn't in the app yet. It's being tested against real catches from days it has never seen, under rules written down before the test, and it goes in only when it passes.

  1. Layers in, one number out. Breaks, color edges and current edges are weighted for the species, then filtered by depth, water temperature for the season, and clarity.
  2. Fixed yardsticks. A 70 in November means the same as a 70 in March. The map is never graded on a curve, so a slow day looks slow.
  3. A blank map is an answer. When the water doesn't support targeting, the score says so instead of shading the best of a bad lot.

Species & regions

Starting narrow on purpose, then growing.

Wahoo off Northeast Florida is the first species and region because that's where the app and the score are being tested. Each new species and region follows once it has passed the same tests.

Where it stands

Tested before anyone is asked to pay.

The app is built and updates every morning and evening with the data above. It's in private testing now, and the beta list hears first when it opens to more anglers.

Expect straight answers. When clouds hide the water, the map stays gray and says how much it missed. When the forecast is rough, the day shows red. The opportunity score stays out of the app until it passes its tests.
