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.
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.
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%).
Poor for swimming (35/100), from 5 available inputs. Supporting this: 1% chance of precipitation. Wind 5 mph from the northeast. Working against it: Measured water temperature 58°F. Provisional data.

Lake Superior - Wisconsin South Shore currently reports 66°F with wind velocity near 2 mph from the SE. Atmospheric forecasts and 24-hour hour-by-hour wind timelines are updated hourly from the National Weather Service gridpoint matching the lake's coordinates.
At Lake Superior - Wisconsin South Shore and surrounding mountain valleys, diurnal heating of the surrounding terrain causes strong thermal pressure differentials known locally as afternoon breezes (such as the Washoe Zephyr at Lake Tahoe). Wind speeds typically peak between 1:00 PM and 5:00 PM before calming near sunset.
For stand-up paddleboarding (SUP), canoeing, and light kayaks, winds under 7 mph (light breeze) offer the safest, glassiest surface conditions. Between 8–14 mph, small wavelets develop, suitable for sailboats and powerboats. Winds exceeding 15 mph create steep whitecaps and rapid drift; winds over 21 mph warrant small craft warnings.
All weather and wind telemetry is fetched directly from the National Weather Service (NOAA - WFO DLH) high-resolution numerical point-forecast API. LakeRadar uses the official gridpoint for Lake Superior - Wisconsin South Shore without artificial smoothing or third-party estimates.
