Satellite SST & Chlorophyll Charts for Offshore Fishing

Chlorofishy shows you real satellite ocean data — sea surface temperature and chlorophyll concentration — on an interactive map. Find temperature breaks, chlorophyll edges, and current boundaries where bait and gamefish concentrate. No login needed to browse daily composites; sign up free, or subscribe to unlock real-time satellite passes, buoys, and alerts.

Ocean Data with Nothing to Hide

Every other fishing chart service shows you “cloud-free” composites — pretty pictures that fill in cloud gaps with stale or modeled data. That temperature break you drove 40 miles to find? It might be 3 days old. Chlorofishy shows you the raw satellite pass with real cloud gaps. Every pixel has a story: which satellite captured it, when, at what resolution, and how fresh the data is.

Toggle between five satellites (VIIRS S-NPP, NOAA-20, NOAA-21, MODIS Aqua, GCOM-W AMSR2) and daily composites. Click anywhere on the ocean to read exact temperature in °F or °C. Chlorophyll clicks also show estimated water visibility — a Secchi depth estimate that spearfishermen and divers actually use for trip planning.

If we fill gaps with composited data, we tell you. If the data is from yesterday, we tell you. No black boxes. Your data, your decision. New here? Our how-to guide covers reading the map, and our articles go deeper on the ocean science behind it.
