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 Dangerous waves and currents are not expected. However, dangerous currents may exist at any time near piers, breakwalls, and river outlets. Always use caution and never swim alone. 
Moderate Breaking waves and currents expected. Stay away from dangerous areas like piers, breakwalls, and river outlets. Always have a flotation device with you in the water
High Life threatening waves and currents expected. Stay out of the water and stay away from dangerous areas like piers and breakwalls.

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.
