Marine Advisory
Marine conditions on eastern Lake Superior are expected to become hazardous. Strong southwest to west winds may create rough conditions, particularly for small craft and open-water navigation. Boaters should be aware of:
- Strong gusts and building waves
- Reduced comfort while on open water
- Changing conditions near exposed shorelines
Preparation Tips
Visitors should dress in layers, as Friday afternoon may feel warm despite strong winds. It’s advisable to carry sunglasses and apply sunscreen due to the high UV index. Additionally, a rain jacket will be necessary for Sunday night and Monday.
While the Victoria Day weekend is often viewed as the unofficial start of summer in Northwestern Ontario, the presence of Lake Superior can prolong the cooler weather in shoreline communities well into June.
