Great Lakes temperatures: Is Lake Michigan warm enough to swim in?
Temperatures across Michigan and Wisconsin hit the 80s on Wednesday, June 11, and are expected to be in the 70s through the weekend, warm enough to tempt people to try swimming in the Great Lakes. The water may even feel warm enough to hop in this weekend in some locations. Lake Erie and Lake Huron have posted readings at or near 70 degrees Fahrenheit, although lake temperatures typically don't peak until late summer/early fall, according to GLISA. In Lake Superior, though, temperatures are still in the 30s in places. Swimming is most comfortable in lake waters at about 70 degrees, according to Here's how warm — or cold — the Great Lakes are: Lake Erie, the shallowest of the Great Lakes, reached 70.2 degrees near Rossford, Ohio, as of June 13. Lake Erie reaches an average of 76.1 degrees Fahrenheit in August. Current temperatures for Lake Erie: Monroe, Michigan: 66.7 Gibralter, Michigan: 63.7 Cleveland, Ohio: 63.6 Grosse Ile, Michigan: 63.1 The warmest water temperature in Lake Huron June 13 was 68 degrees in Saginaw Bay. Lake Huron reaches an average of 69.1 degrees Fahrenheit in August. Current temperatures for Lake Huron: Saginaw Bay, Michigan: 68 Au Gres, Michigan: 64 Port Crescent, Michigan: 58.3 Alpena, Michigan: 57.7 Tawas City, Michigan: 57.2 Port Huron, Michigan: 56.7 Drummond Island, Michigan: 56.7 Mackinac Island, Michigan: 56.1 Port Sanilac, Michigan: 55.9 Safety first: Thinking of swimming alone?

Lake Superior reaches an average of 64.6 degrees Fahrenheit in August. Current temperatures for Lake Superior: Paradise, Michigan: 50.2 Sault Ste. Marie, Michigan: 48.2 Ontonagon, Michigan: 46.6 Marquette, Michigan: 44.8 Ashland, Wisconsin: 43.8 Grand Marais, Michigan: 40.3 Copper Harbor, Michigan: 39.4 Temperatures climb in the spring and summer months, reaching peak temperatures in the late summer and early fall, according to GLISA, a collaborative between Michigan State University, University of Michigan and the National Oceanic and Atmospheric Administration. The National Weather Service says your body can enter a cold shock if exposed to water between 50 and 60 degrees, spiking an elevation in heart rate, blood pressure and eventually panic, fear and stress. Prolonged exposure could result in loss of muscle control in your arms, legs, hands and feet, triggering hypothermia among other things that can be fatal.

Swimmer's itch is a skin rash caused by an allergic reaction to microscopic parasites that infect some birds and mammals, according to the Centers for Disease Control and Prevention. The parasites are released from infected snails into fresh and salt water (such as lakes, ponds, and oceans). While the parasite's preferred host is the specific bird or mammal, if the parasite comes into contact with a swimmer, it burrows into the skin causing an allergic reaction and rash. Swimmer's itch is found throughout the world and is more frequent during summer months. Swimmer's itch is often incorrectly attributed to E. coli exposure, according to the Clean Lakes Alliance.

Water temperature throughout the Great Lakes currently do not exceed 68 degrees Fahrenheit. The warmest water temperature in the Great Lakes Monday, May 19, is 63.5 degrees Fahrenheit near Bay City, and the surface temperature is 41.9 degrees near Toronto, according to Lake Superior, the largest of the lakes, had its highest reading at 52.5 degrees Fahrenheit near Sault Ste.

Prolonged exposure could result in loss of muscle control in your arms,legs, hands and feet, triggering hypothermia among other things that can be fatal. The first day of summer is marked by the summer solstice, which can be either June 20 or 21, occurring when the Earth tilts toward the sun is at a maximum, reporting from the Detroit Free Press shows. This year's is on June 20, although summer temperatures may start earlier. The five Great Lakes include, Lake Michigan and Lake Huron, connected at the Straits of Mackinac, Lake Superior, Lake Erie and Lake Ontario. The Great Lakes: account for 94,250 square miles of water. account for 84% of North America's surface fresh water. account for 21% of the world's supply of surface fresh water. Lake Superior is the largest Great Lake also the biggest lake in the U.S. and the second-biggest lake in the world, it makes up 31,700 square miles. Detroit Free Press contributed reporting.

The 'least spectacular' of the Great Lakes is a devastating snow machine
'What we're seeing this year is the fact that the Lakes are staying warm, relatively ice-free far later into the winter season, and you still have cold air outbreaks,' says Rood. A study published in the Journal of Climate in 2003 found 'a statistically significant increasing trend in snowfall for the lake-effect sites' throughout the 20th century across all Great Lakes. And another study looking at Buffalo, New York and published in the journal Earth's Future last June found that the conditions that produce lake-effect snow could produce 14 percent more precipitation as the planet warms, though some of that may fall as rain. Modeling by the Great Lakes Integrated Sciences and Assessments (GLISA) program suggests that air temperatures in the region could rise by up to 11˚F by 2100, a change that would create warmer lake water as years of warmer weather unfold. Given the complex relationship between Arctic air flows and changing climate patterns, experts say they can't predict with certainty what future snowfall around the Great Lakes will look like, though the ingredients for severe snow storms—warming lake surface water and shots of extremely cold Arctic air—are likely to continue. 'The frequency of air crossing the Great Lakes that is cold enough to produce lake-effect snow is likely decreasing on average,' says David Kristovich of the University of Illinois Urbana-Champaign's department of climate, meteorology, and atmospheric sciences.
