NOTE: The webcam has been experiencing technical difficulties. We are working on resolving the problems as quickly as possible. Sorry for the inconvenience.The wave sensor has been removed for the season. Model results are available now. The model does not account for ice that may dampen wave heights.

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.
