Marine and Outdoor Considerations

Boaters on Lake of the Woods should remain alert for thunderstorms, shifting winds and sudden reductions in visibility caused by rain or smoke.

Thunderstorms can produce strong wind gusts, lightning and rapidly building waves. Boaters should have a reliable way to receive updated forecasts and should be prepared to return to shore when threatening clouds approach.

Lightning can strike well away from the heaviest rainfall. When thunder is heard, the safest choice is to move indoors or into a fully enclosed vehicle.

Wardrobe Recommendations

Light, breathable clothing will be the most comfortable choice because of the heat and humidity. A waterproof jacket or compact umbrella will be useful as showers become more likely.

Choose water-resistant footwear for walking on wet streets, trails or docks. Boaters should wear approved personal flotation devices and carry additional rain protection.

Sunscreen, sunglasses and a hat are recommended because the UV index will be high, even with considerable cloud cover.

People affected by wildfire smoke may also wish to carry a well-fitting respirator, such as an N95, for periods when smoke becomes more noticeable.

Weather Trivia

Lake of the Woods contains thousands of islands and covers a vast area along the Ontario–Manitoba–Minnesota border. Large lakes can influence nearby weather by moderating temperatures and adding moisture to the lower atmosphere.

During warm and humid summer conditions, that additional moisture can contribute to localized cloud, fog and showers. Weather can therefore vary noticeably between Kenora, exposed sections of the lake and sheltered bays.
