The 2017 Lake Michigan Beach Services Program offered by the National Weather Service Milwaukee/Sullivan   

Will you be safe from dangerous swimming conditions this year?  

The National Weather Service (NWS) Beach Services program provides beach-goers with a daily beach forecast and "swim risk".  By checking the "swim risk" each day, you can avoid an unnecessary trip to the beach due to expected dangerous swim conditions. 

The NWS Beach Services program also provides decision support to beach managers, park patrols, and other officials for staffing, beach closures, and other beach-related concerns.  

The NWS office in Milwaukee/Sullivan will provide a daily Recreational Beach Forecast for beaches along Lake Michigan from Sheboygan to Kenosha.  

The Recreational Beach Forecast will be issued around 4 am CDT and will provide a forecast of weather and water conditions expected at Lake Michigan beaches for the coming day and night.  Forecast information for the beach will include expected weather, wave heights, water and air temperature, beach winds, Ultraviolet Index and sunrise and sunset. Most importantly a Swim Risk will be given that is based on the expected wave heights and winds.  

A Low swim risk implies that dangerous waves and currents are not expected at the beach.  However, dangerous currents may exist at any time near piers, breakwalls, and river outlets.  Always use caution and never swim alone.

A Moderate swim risk implies that breaking waves and currents are expected at the beach.  Stay away from dangerous areas like piers, breakwalls, and river outlets.  Always have a flotation device with you in the water.

A High swim risk implies that life threatening waves and currents are expected.  Stay out of the water, and away from dangerous areas like piers and breakwalls. 

A second Recreational Beach Forecast will be issued around 5 pm CDT, providing a detailed beach forecast for the coming night and following day. 

Here is a sample Recreational Beach Forecast for Lake Michigan beaches in Sheboygan county:

If winds and waves for the coming day or second day are expected to result in a High swim risk, and weather conditions support beach visitors, then the National Weather Service in Milwaukee/Sullivan will issue a Beach Hazard Statement.  The Beach Hazard Statement emphasizes the dangerous swimming conditions expected, what types of currents have a greater likelihood of occurring, and which beaches would be most susceptible to these conditions.  

Here is a sample Beach Hazard Statement for Lake Michigan beaches in Milwaukee, Racine and Kenosha counties:

On the National Weather Service Milwaukee/Sullivan webpage, the Beach Hazard Services program can be accessed by scrolling down to the bottom of the page and clicking on the "Beach Hazards" link in the Hazards column, as illustrated below:

The above links will access the new Great Lakes Beach Hazards webpage.  The direct link is https://www.weather.gov/greatlakes/beachhazards

By adding "#mkx" to the end of the web address, you can quickly zoom into southeast Wisconsin when opening the page.  The web address for this capability would then be https://www.weather.gov/greatlakes/beachhazards#mkx. The below closeup of southeast and east central Wisconsin would then display:

By hovering over the marine zone adjacent to the desired county, a forecast of waves, temperature, weather and winds will pop up for the county as well as the expected swim risk for the coming day.  Click on the marine zone for the full text of the Recreational Beach Forecast.  

The marine zone will be highlighted in either green, yellow or red to indicate the swim risk for the coming day. 

If the marine zone is highlighted in red, then the swim risk for the coming day or next day is High, and a Beach Hazard Statement will be in effect.  Hover over the adjacent county to get more details on the Beach Hazard Statement.  

Other features and capabilities of the Great Lakes Beach Hazard webpage include having the ability to display radar data, regional warnings, forecast wave height, current lake surface temperature and lake currents. To access this data, click on the layer icon layer iconlocated in the lower right of the display window. Then click on "Observed Data" or "Forecast Data" to access these features.  You also have the capability to change the background display.

Here are examples of some of the features:

Also available on the Great Lakes Hazard webpage is access to the Great Lakes Current Incident database. This is a database of current related incidents (rescues and drowning fatalities) on the Great Lakes since 2002.  This database includes information collected from newspaper articles, online articles, and police reports.  

The main display of the Great Lakes Current Incident webpage graphically illustrates the number of incidents that have occurred in each U.S. county bordering the Great Lakes since 2002.
