Duluth, Minnesota – Boaters and mariners on western Lake Superior should prepare for persistent east winds through Saturday, with afternoon gusts topping 15 knots from Duluth to Grand Marais and beyond. The strongest winds are expected each day between late morning and late afternoon, raising concerns for choppy waters and difficult navigation across bays like Silver Bay, Saxon Harbor, and Big Bay.
According to the US National Weather Service in Duluth, winds will hold steady from the east through the workweek, turning westerly on Saturday. Maximum wind gusts are forecast to reach 14–18 knots across locations including Port Wing, Taconite Harbor, and Two Harbors, with brief spikes possible during afternoon thunderstorms. Overnight hours will bring calmer conditions, but boaters should stay alert for quick changes, especially if thunderstorm activity increases.
Sand Island, Stockton Island, and the Twin Ports could see the strongest gusts from noon to 6 p.m. daily, making early launches and evening returns safer options for small craft. The National Weather Service urges anyone on the water to wear life jackets, check marine weather updates before departure, and avoid non-essential trips during peak wind periods.
East winds are expected to ease by Saturday as the pattern shifts, but higher gusts may return with any storms. Additional marine advisories may be issued this week.
Five Day Forecast:
- Tuesday: East winds 12–15 kt, gusts highest 2–6 p.m., calmer overnight.
- Wednesday: Persistent east winds 13–16 kt, strongest late morning to late afternoon.
- Thursday: Afternoon gusts 14–17 kt, potential for isolated thunderstorms.
- Friday: Gusts peaking 15–18 kt, roughest waters noon to 6 p.m.
- Saturday: Winds becoming westerly, gusts decrease to 8–12 kt, improving conditions.
