Swim Risk Surf Forecast
The Surf Forecast is issued from Memorial Day to Labor Day

Notice: A Beach Hazards Statement is issued (Memorial Day through Labor Day) when the risk level reaches  HIGH  and weather conditions are conducive to beach activity.  Wind and wave conditions can change quickly, so be prepared for hazardous swim conditions at any time. 

Swim Hazard Risk Level Types of Hazards Radar Information
Low A low risk of swimming hazards imply that large waves and strong currents are not expected along the shore.
Moderate A moderate risk of swimming hazards imply that large waves and strong currents are likely along the shore. Only experienced swimmers should consider entering the water.
High A high risk of swimming hazards imply dangerous waves and currents are expected along the shore. Swimming conditions may be life-threatening to anyone entering the water.

Structural Currents - Wave action forces water out along the structure as a strong current.

Breaking Waves - Waves on Great Lakes have short periods of 3 to 5 seconds. Waves repeatedly hit you and wear you down. Waves of 3 to 5 feet can knock an adult off their feet.

Longshore Currents - With strong north or south winds, longshore currents can occur. These currents will exert a force on you making it difficult to remain in place. The current will push you down the beach over time.

Rip Currents - Rip currents can form in gaps in sand bars. Water can surge offshore through the gap after it washes up on the beach with a wave.
