How to Cope and Stay Safe in Extreme Heat in Grand Rapids, Michigan

Summer in Grand Rapids can bring stretches of hot, humid weather—especially with heat waves becoming more common across West Michigan. Even though we’re known for long, cold winters and lake-effect snow, extreme heat is a serious health risk here too, especially when humidity is high and nighttime temperatures stay warm.

Prolonged heat can cause dehydration and overheating, leading to serious and potentially life-threatening problems such as:

  • Heat exhaustion
  • Heatstroke
  • Worsening of heart, lung, and kidney diseases
  • Triggering heart attacks or strokes

Local hospitals in Grand Rapids—such as Corewell Health (formerly Spectrum Health), Trinity Health Grand Rapids, Metro Health, and Mercy Health—see an increase in heat-related illnesses during severe heat waves. Knowing how to prepare and protect yourself can help you avoid an emergency visit.

Who Is Most at Risk in Extreme Heat?

Extreme heat can affect anyone in Grand Rapids, but some people are more vulnerable, including:

  • Adults over age 65
  • Babies and young children
  • Pregnant women
  • People with chronic conditions (heart disease, lung disease, kidney disease, diabetes, mental health conditions)
  • People taking certain medications (diuretics, some heart or blood pressure medicines, some psychiatric medications)
  • People who are socially isolated or living alone
  • People who work or exercise outdoors (construction workers, landscapers, delivery drivers, athletes, coaches)
  • People without air conditioning or with limited access to cool spaces

If you or someone you care for falls into one of these groups, it’s especially important to plan ahead for hot, humid days in West Michigan.

Plan Ahead for Extreme Heat in Grand Rapids

Stay Informed About Local Weather and Heat Alerts

  • Follow heat advisories and warnings from:
    • National Weather Service Grand Rapids
    • Local TV and radio stations (WOOD TV8, FOX 17, WZZM 13)
  • Check the forecast regularly during summer, especially when humidity is high.
  • Pay attention to the “heat index” (how hot it feels with humidity) and overnight lows—heat is more dangerous when homes don’t cool down at night.

Keep Cool at Home and in the Community

Use Air Conditioning Safely and Efficiently

  • Use air conditioning if you have it. To reduce energy costs:
    • Set your thermostat a bit higher (around 78–80°F / 26–27°C)
    • Use fans to help circulate cool air
  • Electric fans can help when indoor temperatures are below about 102–104°F (39–40°C). Above that, fans alone may not prevent overheating.

Simple Ways to Cool Your Body

  • Keep your skin damp:

    • Use a spray bottle or damp sponge on your face, neck, and arms
    • Soak a towel in cool tap water and wrap it loosely around your head or neck
    • Take cool showers or baths, or soak your feet in cool water
    • Wrap ice cubes in a damp towel and place around your neck or on your wrists

  • Wear:

    • Light-colored, loose-fitting, breathable clothing
    • A wide-brimmed hat and sunglasses when outdoors

Keep Your Home Cooler

  • Close blinds or curtains on sun-facing windows during the day.
  • Use reflective shades or blackout curtains if possible.
  • Open windows in the evening or early morning if it’s cooler outside than inside.
  • If you own your home, consider long-term improvements:
    • Adding insulation or reflective coatings
    • Installing exterior shades or awnings
    • Planting trees or shrubs to provide shade around your home

Use Community Cooling Options in Grand Rapids

If your home is very hot and you don’t have air conditioning:

  • Spend time in air-conditioned public spaces, such as:
    • Grand Rapids Public Library branches
    • Woodland Mall, Tanger Outlets, or other shopping centers
    • Movie theaters
    • Community centers and some churches
  • During declared heat emergencies, the Kent County Health Department and City of Grand Rapids may open designated cooling centers. Check:
    • Kent County Health Department website
    • City of Grand Rapids and Grand Rapids Public Health announcements
    • Local news and social media for updates

Stay Hydrated in Hot Michigan Weather

During hot, humid days—especially if you’re outdoors or active—your body loses more fluid through sweat.

How to Stay Hydrated

  • Drink water regularly, even before you feel thirsty.
  • Take a reusable water bottle with you whenever you leave home.
  • Limit or avoid:
    • Alcohol
    • Sugary drinks
    • Excessive caffeine (can worsen dehydration for some people)

If your doctor has told you to limit fluids (for example, for heart or kidney disease), ask your Grand Rapids primary care provider or specialist how much you should drink during hot weather.

Signs of Dehydration

Watch for:

  • Thirst
  • Dry mouth or dry lips
  • Feeling lightheaded or dizzy
  • Fatigue or unusual tiredness
  • Dark yellow, strong-smelling urine
  • Urinating less often than usual

If these symptoms don’t improve after drinking fluids and cooling down, contact your doctor or an urgent care clinic in Grand Rapids.

Adjust Your Schedule: Avoid the Hottest Part of the Day

Reschedule or Cancel Non-Essential Outings

On extreme heat days in Grand Rapids:

  • Cancel or postpone non-essential appointments, errands, and outdoor plans.
  • Schedule essential activities for:
    • Early morning
    • Late evening
      when temperatures and sun intensity are lower.

If You Must Go Outside

  • Take a full water bottle with you.
  • Seek shade as often as possible.
  • Wear:
    • A wide-brimmed hat
    • Lightweight, loose clothing
    • Broad-spectrum sunscreen (SPF 30 or higher), reapplied every 2 hours or after sweating or swimming

Special Considerations for Older Adults in Grand Rapids

Older adults (especially those over 65) are more likely to:

  • Have chronic medical conditions
  • Take medications that affect temperature regulation or fluid balance
  • Live alone or have limited mobility

Steps for Older Adults and Their Caregivers

  • Before summer, review chronic conditions and medications with a local provider (e.g., at Corewell Health, Trinity Health Grand Rapids, Metro Health, or Mercy Health).

  • Ask if you are at higher risk for heat-related problems and whether:

    • Fluid intake should be adjusted
    • Any medications should be temporarily changed during extreme heat

  • Create a personal heat plan:

    • Identify cool places you can go if your home gets too hot
    • Arrange regular check-ins with family, friends, or neighbors
    • Keep emergency numbers easily accessible

Keeping Babies and Children Safe in the Heat

Babies and young children are less able to regulate their body temperature and can overheat quickly—especially in humid Michigan summers.

Hydration and Feeding

  • Offer extra breastfeeds or bottle feeds to babies during hot weather.
  • Encourage older children to drink water regularly, even if they say they’re not thirsty.
  • Avoid very sugary drinks and energy drinks.

Clothing and Cooling

  • Dress babies and children in light, loose-fitting clothing.
  • Keep babies in the shade when outdoors.
  • For babies in strollers:
    • Use a light, breathable muslin or cotton cloth to provide shade
    • Keep the covering loose to allow airflow
    • Use a battery-operated clip-on fan if available
    • Keep the cloth slightly damp with a spray bottle to help cooling

Never Leave Children in Cars

  • Never leave babies, young children, or pets in a parked car—even for a few minutes.
  • In the sun, car interiors in Grand Rapids can reach dangerous temperatures within minutes, even on milder days.

Working or Exercising Outdoors in West Michigan Heat

Construction workers, landscapers, delivery drivers, athletes, and anyone training outdoors along the Grand River trails or at local parks (e.g., Millennium Park, Riverside Park, Huff Park) are at higher risk in extreme heat.

If You Work Outdoors

  • Where possible, postpone heavy outdoor work to a cooler day.
  • If work must continue:
    • Schedule the heaviest tasks for early morning or later evening.
    • Take frequent, longer rest breaks in shaded or air-conditioned areas.
    • Use any natural air movement or fans to help cooling.
    • If available, outdoor misting fans can help lower the surrounding temperature.

If You Exercise Outdoors

  • Before exercise:

    • Drink at least about 16–20 oz (around 500 ml) of fluid in the 2 hours before activity.

  • During exercise:

    • Aim to drink about 7–8 oz (around 200 ml) every 20 minutes.

  • Choose:

    • Shaded routes or parks
    • Cooler times of day (early morning or late evening)

  • Consider moving your workout indoors (gym, community center, home workout) on extreme heat days.

How You Can Help Others During a Heat Wave

Extreme heat can be especially dangerous for people who are isolated, elderly, or have chronic health issues.

Check In on Family, Friends, and Neighbors
