Grand Marais, Lake Superior, MN · Oct 9, 2:18 PM UTC
Good for fishing (83/100), from 6 available inputs. Supporting this: Wind 0 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 (82%) because some inputs are unavailable or older than ideal.
Excellent for boating (99/100), from 4 available inputs. Supporting this: Wind 0 mph from the south. Gusts to 4 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 (62/100), from 4 available inputs. Supporting this: Gusts are within 4 mph of sustained wind, so the breeze is steady. No active official alerts for this lake. Working against it: Wind 0 mph is light; expect limited sailing. Not available from a verified source for this lake: visibility. Confidence is high (88%).
Fair for kayaking (72/100), from 5 available inputs. Supporting this: Wind 0 mph from the south. Gusts to 4 mph. Water temperature is 53°F (combined air+water: 95°F). Cold shock hazard: sudden immersion below 55°F poses serious risk. Confidence is high (90%).
Surface water measured at 53°F. Cold shock reflex presents an immediate drowning risk.

Individual boat ramp GPS coordinates are maintained under the jurisdiction of MN Parks & Wildlife Authority. Public boaters should verify seasonal launch water levels, gate hours, and daily vehicle/vessel fees before traveling.
Known for its reliable water levels and open navigation, Gunflint Lake in MN welcomes visitors for boating, paddling, and shoreline recreation. The waterbody supports an active angling community pursuing both native and stocked sportfish. Verifying ramp depth and seasonal regulations helps ensure safe launch operations.
Valid freshwater sport fishing license issued by Minnesota Department of Natural Resources (MNDNR) 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 State & Local Authorities. 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 Northern Pike, Walleye, Mackinaw (Lake Trout), Brook 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.
