SST (Sea Surface Temperature)

Important notes

  • You can either use our composite image or raw imagery as it comes in from the satellites
  • Our Cloudfree SST image has a contoured or shaded option you can select in the IMAGERY & OVERLAYS menu.

Cloudfree SST

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

Use the Cloudfree composite image when cloud cover impacts raw imagery. It is updated daily, but the quality of latest SST will impact the reliability of this image.

FishTrack’s Cloudfree SST imagery 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?


Latest SST

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

Hit the IMAGERY & OVERLAYS button and see the Latest SST under the Imagery menu.

You'll see a list of images as they come in from the satellite.

In short, we receive data recorded by the satellite. We ask the data whether there is any data for the defined region. If there is, we will overlay the data on a map and upload an image of the region.

  • If the satellite's reach didn't cover the full region, you'll see a "half image" in which there is a sharp cutoff of data.
  • If cloud cover was preventing the satellite recording all data in the region, we'll upload a largely blank image with a few new data patches (even if it is just a pixel).
  • If no data was recorded for the region by the satellite, we will not upload an image.


Using SST to find fish.

Use temperature data alongside information about the species you are targeting

If transitional areas (between temperatures) are limited, use other data to identify "breaks" (see Limitations & advantages of the tools article to learn more about breaks).

Through colder periods, 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".

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
