The deepest point reaches about 1,333 feet, and the surface sits near 602 feet above sea level. The water surface spans about 20,300,000 acres, making it a very large body of water. Research-grade observations nearby include Yellow Perch, Northern Pike, Brown Trout, and Rainbow Trout. Other waters in the region include Lake Namakagon. LakeRadar pulls readings from a mapped water gauge, so current water data is shown when the station reports. Below you will find an hourly and 7-day forecast, wind and gust outlook, water readings, fishing conditions, and activity scores for boating, paddling, and swimming. Check the hourly forecast and activity outlook below before heading out to Lake Superior - Wisconsin South Shore.
This page covers a named shoreline area, not the whole lake. Conditions vary widely across open water, so treat this forecast as local to the coordinates shown and check the official source before heading out.

NOAA GLERL GLSEA surface temperature at 46.612, -90.878 · Oct 8, 12:00 PM UTC
Good for fishing (85/100), from 6 available inputs. Supporting this: Wind 5 mph from the northeast. Measured water temperature 58°F. Provisional data. Not available from a verified source for this lake: pressure trend. Confidence is moderate (81%) because some inputs are unavailable or older than ideal.
Good for boating (85/100), from 4 available inputs. Supporting this: Wind 5 mph from the northeast. Gusts to 12 mph. Not available from a verified source for this lake: visibility and conditions, verified water access. Confidence is moderate (84%) because some inputs are unavailable or older than ideal.
Fair for sailing (73/100), from 4 available inputs. Supporting this: Gusts exceed sustained wind by 7 mph, making the breeze puffy. 1% chance of precipitation. Not available from a verified source for this lake: visibility. Confidence is high (88%).
Fair for kayaking (71/100), from 5 available inputs. Supporting this: Wind 5 mph from the northeast. Gusts to 12 mph. Combined air and water temperature is 119°F (below the 120°F safety guideline). Thermal protection recommended for paddle craft. Confidence is high (90%).

Individual boat ramp GPS coordinates are maintained under the jurisdiction of U.S. Geological Survey monitoring location defines this shoreline area. Public boaters should verify seasonal launch water levels, gate hours, and daily vehicle/vessel fees before traveling.
Lake Superior - Wisconsin South Shore is a versatile Great Lakes shoreline region in WI, administered by U.S. Geological Survey monitoring location defines this shoreline area to provide safe, sustainable outdoor recreation for all visitors. The lake supports active watersports, pontoon cruising, and bank fishing along accessible public easements. Checking current weather alerts and wave forecasts ensures a safe trip.
Valid freshwater sport fishing license issued by Wisconsin Department of Natural Resources (WDNR) is required for anglers age 16+. Digital license on mobile is accepted.
Current motorized watercraft registration mandatory. Practice Clean, Drain & Dry protocols: drain all livewells and inspect props before launching. Life jackets required for all passengers.
Public shoreline and boating access managed by U.S. Geological Survey monitoring location defines this shoreline area. Verify seasonal gate hours, launch fees, and parking rules before travel.
High-speed motorboating, pontoon cruising, wakeboarding, and water skiing across main channels. Target gamefish include Yellow Perch, Northern Pike, Brown Trout, Rainbow Trout. Morning hours typically provide optimal glassy conditions for kayak and stand-up paddleboard (SUP) touring.
Warm water temperatures, peak swimming, active watersports, and open full-service campgrounds. Highest weekly attendance; plan early arrivals on summer weekends.
Spring pre-spawn and fall feeding transitions create prime trophy angling conditions. Cooler air, lower boat traffic, and vibrant seasonal shoreline foliage.
Northern cold winter conditions with freezing air temperatures and potential surface ice formation. Ramps and water systems may be winterized. Confirm open status before visiting.
