Switch from RipCharts. Every pass, every region, one price.

What you keep

• Every satellite pass — The polar-orbiting satellites in NOAA’s own ACSPO L3U stream (VIIRS and AVHRR) across all 15 regions. Drawn as observed at 0.02°, clouds as holes; plus hourly geostationary frames from Himawari-9 AHI, GOES-19 ABI, GOES-18 ABI and Meteosat-10 SEVIRI in every one of the 15 regions.
• Composites — 24-hour and 72-hour freshest-pixel composites of those passes — the 72-hour composite is the cloud-free SST, the product RipCharts sells as "Cloud Free" — and the daily gap-filled field.
• 5-day SST forecast — Five days ahead from the Copernicus Marine GLO12 model, on the same field as the 7-day playback — the horizon RipCharts Premium sells. A day the bake misses shows the most recent complete field with its date on it, never a hole.
• Chlorophyll by satellite day — SNPP VIIRS and NOAA-20 VIIRS over AU East Coast, AU West Coast, New Zealand, South Australia & West Vic and Top End & Gulf of Carpentaria (IMOS ocean colour); SNPP VIIRS, NOAA-20 VIIRS and NOAA-21 VIIRS over the other 10 regions (NASA OB.DAAC) — one image per satellite per day at 0.0225°, with a 3-day composite.
• Sea-surface height — The height field coloured over the range in view, with labelled contours in cm — across AU East Coast, AU West Coast, New Zealand, US East + Gulf, US West Coast, Hawaii, Baja & Sea of Cortez, South Australia & West Vic, Top End & Gulf of Carpentaria, Caribbean & southern Gulf, Eastern Tropical Pacific, South-west Pacific and Canadian Maritimes.
• Surface salinity — A modelled surface salinity field (Copernicus Marine, 1/12°), coloured over the range in view, daily, for every covered region — with the value in PSU at the tap point. It is model output and the map says so.
• Temperature at depth — A modelled subsurface temperature ladder at 25, 50, 75, 100, 150 and 200 m on the map today, every depth checked against Argo float profiles before it went on — every depth named, where RipCharts lists "SST Sub Surface" with none.
• True colour — NASA VIIRS corrected reflectance, daily.
• Your palette and your unit — The classic spectral ramp, °C or °F, a drag range and isotherm spacing — on the tiles, not a coarse copy.
• History — 30 days of passes and daily composites per region, from the HISTORY control on the pass strip — every pass that leaves the 72-hour strip is kept, and each day gets its 72-hour composite. The archive fills from October 2026, when it went live; RipCharts' archive per region is deeper.

What changes: the price

RipCharts lists 16 regions on its registration page, each a separate subscription at the same price — US$99/yr per region on Standard (web map only, no mobile app) or US$169/yr per region on Premium. Two Premium regions are US$338 a year for one user. Fishare Pro is US$8.99/mo · US$79/yr across every covered region — the daily field across AU East Coast, AU West Coast, New Zealand, US East + Gulf, US West Coast, Hawaii, Baja & Sea of Cortez, South Australia & West Vic, Top End & Gulf of Carpentaria, Caribbean & southern Gulf, Eastern Tropical Pacific, South-west Pacific, Canadian Maritimes, UK & Ireland and Japan & Kuroshio; per-pass SST across all 15 regions — and the forecast app around it is free.

The full RipCharts vs Fishare comparison carries the verified pricing and a per-region cost calculator.

Four steps

1. Open the SST layer. On the map, turn on SST. The first time, a card asks whether you already read SST charts.
2. Set it up. One tap: the classic colour ramp, your temperature unit, and PASSES open. Every satellite overpass of the last three days is listed newest first with its coverage; tap one and it is drawn as the satellite saw it.
3. Bring your waypoints. Open the marks panel and PASTE your waypoint export, or import the GPX. Each becomes a GO TO target.
4. Read what RipCharts cannot show. The daily gap-filled field with the break drawn and labelled in °C, temperature at 25/50/75/100/150/200 m, the per-species habitat score, and playback of where the break has been.

14 days instead of 7 when you start from this guide; no card to start. Or open the SST map first and look around — the card in the SST dock sets the map up the way you are used to.

What you give up

• Android in public release — RipCharts Premium has an Android app. Fishare's is still in testing, so on Android today you use Fishare in the browser. The iPhone app and the web carry everything on this page.

If that is the reason you fish, keep RipCharts. A serious crew can run both.
