Welcome!

      This site is intended to provide real-time wave information at the Mainland Sea Caves, which is part of the beautiful Apostle Islands National Lakeshore. We only intend to provide real-time information, so please check the weather forecast before going on the water! If you are new to kayaking, knowledge of rescue and safety procedures can be learned from local outfitters.

Model    - Indicates reported wave is a model result, not a measured wave.

++ - Indicates a freak wave.

** - Waves traveling from the East or Northeast may be underestimated by the sensor due to the sensor location. Use caution.

N/A stands for Not Available. Wind Data is taken from NOAA's weather station at Devils Island and will often lag wave data.
