The people behind the website have developed a new website that offers real-time wave height information for the Apostle Islands National Lakeshore in Lake Superior.

Now paddlers and boaters can check to see live data from seven spotter buoys recently deployed throughout the islands, plus Chequamegon Bay near Ashland and Siskiwit Bay near Cornucopia. The buoys monitor wave height, water temperature and wind information.

PREVIOUSLY: New weather forecasts coming for outer Apostle Islands Popular with anglers, sailors and kayakers, the area was too far out for a "near shore'' forecast but not as far as "open waters'' of Lake Superior.
The Apostles offer world-class sea kayaking, fishing and sailing in a remote environment, said Lynne Dominy, park superintendent, “but treacherous waves and frigid water temperatures can imperil boaters. We hope boaters will use this system to assess current conditions and to make good decisions before venturing out on Lake Superior.”

The website was developed as part of a yearlong project by the Department of Civil and Environmental Engineering at the University of Wisconsin-Madison and Wisconsin Sea Grant.

Data from the new buoys also will be studied to help forecasters better predict wave heights in the future.
