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.
The following rating system was devised in conjunction with kayak outfitters that routinely guide trips to the sea caves. The recommended skill level is color coded based on wave height.
