SST | Sea Surface Temperature

When you open FishTrack, our CLOUDFREE SST product will likely already be overlayed on the map.

Tip – you can toggle between a Contoured or Shaded SST overlay by clicking the Imagery & Overlays button (#5 on the App Map), and then Cloudfree SST under the IMAGERY header



  • Use the Cloudfree composite image when cloud cover impacts raw imagery
  • When cloud cover isn't an issue, raw imagery under "Latest SST" will give the best resolution
  • Use temperature data alongside information about the species you are targeting
  • If transitional areas (between temperatures) are limited, use other tools to identify "breaks"

Sea temperature imagery updates the most frequently, making it a valuable tool.

Through colder periods; the SST maps can help us identify different temperature transitions — areas in which specific fish can be found. Different fish species lock into different temperatures.

In the summer (when the larger body of water has heated up) other tools (SSH, Chlorophyll, True Color) become more important to identify areas of transition or "breaks".

FishTrack’s Cloudfree SST imagery — updated daily — is produced using multiple satellite SST sources and aided by computer modeling to fill in areas blocked by cloud cover. The ultimate tool to help offshore anglers pinpoint and precisely locate desirable temperature breaks offshore. Why are my Cloud-Free SST Charts One Day Old?

Locations of various fish species are affected by water temperatures, time of year and availability of food. Sea surface temperature (SST) plays an integral role in targeting species in their respective seasons. For Southern California, for example, these are the best months to target these species:

  • Bluefin Tuna – June to October
  • Yellowfin Tuna  – July to October
  • Wahoo – July to September
  • Bluefin tuna – March to November
  • Albacore – April to November
  • Dorado – April through September
