Excellent for boating (96/100), from 4 available inputs. Supporting this: Wind 5 mph from the south. Gusts to 10 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 (81/100), from 6 available inputs. Supporting this: Wind 5 mph from the south. Measured water temperature 53°F from a representative gauge 28.6 mi away. Provisional data. Not available from a verified source for this lake: pressure trend. Confidence is moderate (72%) because some inputs are unavailable or older than ideal.
Fair for kayaking (69/100), from 5 available inputs. Supporting this: Wind 5 mph from the south. Gusts to 10 mph. Water temperature is 53°F (combined air+water: 105°F). Cold shock hazard: sudden immersion below 55°F poses serious risk. Confidence is high (90%).
Very Poor / Avoid for swimming (24/100), from 5 available inputs. Supporting this: No active official alerts for this lake. 0% chance of precipitation. Working against it: Measured water temperature 53°F from a representative gauge 28.6 mi away. Provisional data. Immersion shock hazard: water below 55°F poses severe cold shock and rapid hypothermia risk. Air temperature 52°F. Water temperature is 53°F (below 55°F). Severe cold shock and hypothermia hazard upon immersion. Confidence is moderate (75%) because some inputs are unavailable or older than ideal.

Gunflint Lake currently reports 50°F with wind velocity near 8 mph from the S. 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 Gunflint Lake 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 Gunflint Lake without artificial smoothing or third-party estimates.
