What to watch in Lake Michigan
Lake Michigan’s long north-south axis lets a sustained northerly or southerly wind build large, steep seas over its full fetch, sometimes within hours. Summer stratification is sharp and wind-driven upwelling can swing nearshore water temperature 15–20°F in a day, so watch wind direction and buoy temperatures together.
