Using the latest satellite and software technology, we can now see the surface temperature THROUGH the clouds.
Use our Cloud Free Sea Surface Temperature maps to point you in the right direction even when Mother Nature isn’t letting us have a look at the true sea surface temperatures.
Satfish’s Cloud Free Sea Surface Temperature chart combines high-resolution sea surface temperature data blended with lower-resolution microwave SST data to produce the highest resolution cloud-free SST images available. As a result of the different technologies used to measure SST, Cloud-Free Sea Surface Temperature charts will usually appear much smoother than high-resolution Sea Surface Temperature charts especially when it’s cloudy. But when skies are clear, the high-resolution SST data will show through better and highlight more fine-scale breaks and eddies in the blended cloud-free SST image.
Cloud-free sea surface temperature images are produced daily for all of our regions and can be very helpful in helping locate warmer water currents that hold pelagic fish during periods of overcast and poor weather.

Frequently Asked Questions
What are Cloud Free Sea Surface Temperature (SST) charts?
Cloud-free SST charts estimate sea surface temperature even when clouds block the view of traditional satellite SST. They’re designed to help you stay on fish when overcast weather makes standard SST maps hard to use.
How do Cloud Free SST charts work “through the clouds”?
These charts blend high-resolution infrared SST with lower-resolution microwave SST, which can better handle cloudy conditions. The result is a cloud-free temperature map created from multiple satellite technologies.
Why do Cloud Free SST images look smoother than regular high-resolution SST?
Because microwave SST is lower resolution, the blended map often appears smoother, especially on cloudy days. When skies clear, more high-resolution detail shows through, and you’ll see sharper breaks and eddies.
When should I use Cloud Free SST for fishing?
Use Cloud Free SST during overcast days, foggy stretches, or stormy weather when standard SST charts have too many missing areas. It’s especially useful for tracking warmer water currents that can hold pelagic fish.
Can I still find temperature breaks and eddies with Cloud Free SST charts?
Yes, but fine-scale features may be less crisp during heavy cloud cover due to the smoothing effect of the blend. On clearer days, the chart can highlight more detailed breaks and eddies as high-res data becomes stronger.
How often are Cloud Free SST charts updated?
Cloud-free sea surface temperature images are produced daily for all regions. That daily refresh helps you follow shifting currents and temperature trends across changing weather.
