About FishRadar

Last updated: 30 July 2026.

FishRadar scores fishing conditions. Give it a coast, a lake or a river and it returns a 0–100 number for right now, built from live ocean and weather data rather than from folklore — plus the seasonal picture, the species that water is known for, and the fishing regulations that apply there where we have verified them.

It is an app for iOS and Android, and a website publishing forecasts for 851 named spots across every ocean basin, in 17 languages.

Who builds it

FishRadar is built and operated by Linkanlabs.

What the forecast is, and is not

It is a comparison of measured conditions against the conditions that score well at that place: water temperature and its departure from the seasonal normal, thermal structure, wind and wave, barometric pressure trend, current, tide phase where tidal range matters, chlorophyll, depth from bathymetry, and solunar timing.

It is not a prediction that you will catch fish, and we will not describe it as one. A score of 80 says the water is behaving the way it behaves on good days there. It does not know about the boats that worked the spot yesterday, the hatchery truck, or the algal bloom that arrived this morning. Fish forecasts explained sets out the limits in detail, and the methodology page documents the model itself.

Where the data comes from

  • Ocean and atmosphere: open model and satellite sources — sea-surface temperature and anomaly, waves, wind, pressure, currents, salinity, chlorophyll.
  • Bathymetry: GEBCO.
  • Tides: NOAA CO-OPS astronomical predictions for the United States. Coverage outside the US is limited, and pages do not claim tide data they do not have.
  • River flow: USGS gauges where a gauge sits near a scored US freshwater spot. Elsewhere there is no flow data, which the relevant pages state.
  • Species: public biodiversity and fisheries datasets, licence terms respected, plus hand curation.
  • Regulations: official government and fisheries-agency documents, compiled by hand, each rule carrying its source and verification date.

What we publish openly

Two datasets under CC-BY, because a forecast whose method nobody can inspect is worth less than one they can: see /datasets/. Corrections and reuse are welcome under the licence.

How we handle being wrong

Automated systems at this scale generate errors, and this one has. Our editorial and corrections policy states how each kind of content is produced, what we refuse to do (no invented numbers, no stale data presented as current, no paid placement), and how to get an error fixed. Reports that affect legality or safety — a wrong size limit, a protected species shown as keepable — jump the queue ahead of everything else.

Regulations are a summary, never legal advice. Fishing law changes and varies by water. Check the authority named on the page before you keep a fish.
