How to Use Buoy SPTM4 Data
Buoy SPTM4 shows live marine conditions for GLOS Weather Station, including wave height, wind speed, gusts, pressure and related station data that can help with go or no-go decisions.
The latest reading is about latest readings are unavailable for wave height and 5.7 kn for wind speed, which currently points to good conditions. It sits inside the broader Great Lakes picture, but this page helps you judge what is happening at the station itself.
Use this buoy page when you need station-level detail, fresher trend context and camera confirmation rather than a regional average alone.
