FAQ
Where does the Oswego fishing data come from?
Wind, waves, water temperature and pressure come from NOAA NDBC stations 45215, OSGN6, 45012 (first station with a recent reading wins; seasonal buoys are pulled for winter). Lake level is from NOAA CO-OPS station 9052030 (Oswego, NY). When no station reports water temperature, Swelldex uses NOAA GLERL's daily satellite analysis (GLSEA). The forecast and wave forecast come from the National Weather Service.
What does the Oswego bite score mean?
It is a rough 0–9 estimate of how good conditions look for king salmon (chinook), steelhead, smallmouth bass, based on wind and waves, surface water temperature, the time of year, the barometer trend and forecast storms. It does not count fish and it is not a safety rating.
Why is there no tide table?
The Great Lakes have no meaningful tides. Instead, Swelldex shows the lake level against chart datum and how much it moved in the last 24 hours; fast changes usually mean strong wind setup or a seiche.
