Summer 2016:Georgian Bay water levels are modestly above average in Lake Huron-Michigan thanks largely to conditions from a strong El Niño. Warmer air temperatures and warmer water temperatures resulted in less evaporation (note: evaporation increases with greater contrasts in air and water temp). El Niño is weakening, and NOAA is predicting (50% probability) that the Great Lakes may be influenced by La Niña conditions by late fall. Georgian Bay water levels are generally expected to stay above average, but may decline with the cooler weather of La Niña in late Fall. .
