Why is Michigan hot? Causes and heat countermeasures

I will explain in detail the causes of heat in the U.S. state of Michigan, how to cope with it, and cool spots to visit.

1. Causes of Heat in Michigan

Although Michigan is surrounded by the Great Lakes and is often thought of as a cool state, summers can be surprisingly hot depending on the region and weather conditions. The main reasons are as follows:

1. Humid Continental Climate
   In inland areas, the moderating effect of the lakes is weaker, making hot summer days common. Temperatures can occasionally approach 35°C (95°F).
2. Moist Air from the Great Lakes
   Winds from the lakes can sometimes be cool, but on hot days they can raise humidity, making the air feel more stifling.
3. Heat Waves
   In summer, when warm air flows in from the southwest, high temperatures can persist for several days. This is especially noticeable in the southern part of the state (around Detroit and Lansing).
4. Urban Heat Island Effect
   In urban areas such as Detroit and Grand Rapids, heat is retained by asphalt and buildings, preventing temperatures from dropping much at night.

2. Heat Countermeasures

Here are some tips for staying comfortable during Michigan’s summer:

• Use of Air Conditioning and Dehumidification
  Since humidity tends to be high, using both air conditioning and a dehumidifier greatly improves comfort.
• Sun Protection
  Use sunglasses, hats, and sunscreen. UV rays can be strong along the lakeshore.
• Avoid Outdoor Activities in the Hottest Hours
  Stay indoors especially between 1 p.m. and 4 p.m., and schedule outings for the morning or evening.
• Hydration and Electrolyte Replenishment
  Because you sweat more, drink sports drinks and take salt candies regularly.
• Block Heat Indoors
  Use curtains or blinds to block sunlight and prevent indoor temperatures from rising.

3. Cool Spots

Michigan offers many places ideal for escaping the summer heat, thanks to its abundant lakes and forests.

• Mackinac Island
  A popular tourist destination in Lake Huron, with refreshing lake breezes.
• Traverse City
  Located on the Lake Michigan shore, it stays relatively comfortable in summer and is known for its beautiful beaches and wineries.
• Pictured Rocks National Lakeshore
  Along Lake Superior, where the cold lake water keeps the air fresh.
• The Upper Peninsula
  With higher elevation and latitude, it generally stays cooler in summer than the Lower Peninsula.
