Engineered for anglers who fish the reefs, shelf and beyond. Sea temperature, currents, altimetry, chlorophyll, depth, wind, waves and marine park zones, drawn from the world's leading ocean agencies onto one chart. Tap the water and read the real value underneath.
Switch on what matters for the day, exactly as you do in the app. Each layer keeps its own source, time and colour scale, so you always know what you are looking at.

Sea surface temperature
Find the edge, not just the temperature. Hourly Himawari-9 snapshots, 750 m VIIRS overpasses, nightly composites and gap-free analyses, with isotherms that bunch where the water changes fast and stop honestly at cloud.

Currents
The water you will actually drift on. Total surface current with the tide in it, every two hours for the next two days, then the steady daily set out to ten. Measured HF radar wherever a site covers your water.

Two-hourly for 2 days, daily to 10
Analysis · Forecast
Altimetry
Sea level measured from orbit, and the surest way to find an eddy. Warm-core eddies stand high and cold-core eddies sit low, and the altimeter reads straight through the cloud that blinds temperature.

Daily forecast of where eddies are heading
Observation · Analysis
Chlorophyll
The colour of the sea, read as plankton. Where green water meets blue, bait gathers and fish follow. Line a colour edge up with a temperature break and you have the strongest front on the chart.

Depth
The seabed in detail. Contours, multidirectional relief shading and your own depth bands, from a multi-resolution survey composite. Download a region's high-detail archive once and it stays on your phone for good.

Wind
Forecast wind as a moving flow field with arrows, so direction reads even in a still frame. ECMWF leads, chosen for the lowest error against more than a million satellite wind measurements around Australia. GFS gives you a second opinion.

Waves
Height, period and direction, with the wind sea and each swell system shown apart. Live wave buoys along the coast tell you what the sea is doing now, so you can check the forecast against it.

Marine park zones
Know which side of the line you are on. Tap any zone for its name, category and park, and what you may do there: line fishing, spearfishing, collecting, anchoring or crabbing. It answers offline, with each park's own published rules.

The data
Measured, analysed or forecast. The chart says which.
Most fishing apps blend everything into one pretty picture. Sea Layers keeps measurement, analysis and forecast apart, and where a sensor did not see the water, the gap stays visible rather than being filled with an invented value.
Data from NASA and NOAA, Copernicus Marine, ECMWF, IMOS, the Bureau of Meteorology, IMAS and NESP, and Australian marine authorities. The active source, its timing and resolution are shown in the app.
Observation
What a satellite or instrument actually measured.
Cloud, swath edges and coverage gaps stay on the chart.
Analysis
A complete field built from many observations, with no gaps.
Labelled as an analysis, with its source, valid time and resolution.
Forecast
What a model expects next, up to ten days out.
Shown with its run, lead time and grid, so you know how far ahead you are looking.
Offshore
Built for when the reception drops.
Pick your regions and layers at home. The app shows what is stored and what is still missing, and the nautical basemap works offline.
Tap for the real value
Tap anywhere for the reading underneath every layer that is on, measure a distance, and save waypoints.
One timeline for everything
Step back through recent satellite passes and forward through the forecast, with every layer in step.
Profiles for each kind of trip
Save the layers you use for marlin, tuna or bottom bashing, and switch between them in one tap.
Your spots stay yours
Your position, waypoints and where you tap are never uploaded.
On the water
Made in Australia, for Australian water.
Built by a small Australian team who fish these waters, to answer the questions you ask on the way out: where the warm water sits, which way it is moving, and whether the run is worth it.
Take the whole ocean offshore.
Sea Layers is on the App Store for iPhone, covering Queensland, New South Wales, Victoria and Tasmania.
