Cold Water, Falling Temperatures, Frozen Forecast
Clean Lakes Alliance annual Mendota Freeze contest open
Winter is quickly approaching. With the cold temperatures, people around Madison start to ask themselves, “When will our lakes freeze?”
“We experienced a colder than normal November in Madison, with temperatures averaging about five degrees below normal,” said Clean Lakes Alliance Meteorologist Karin Swanson. “The forecast for the next week calls for temperatures near or below freezing, which will help lake temperatures continue to fall.”
More than 165 years of data shows the median freeze date for Lake Mendota is only two weeks away on Dec. 20. Additionally, Lake Mendota has always frozen – even if only for a few weeks. In fact, during the winter of 2001-02, the lake was officially frozen for only 21 days. That three-week ice-on period is much shorter than the record 161 days, set in the winter of 1880-81.
