As temperatures rise and summer begins to take hold, the risk of heat-related illnesses increases—especially here in Wisconsin, where climate conditions are becoming more extreme. To highlight the importance of heat safety, June 4 has been named Heat Awareness Day in Wisconsin.
At Marshfield Insurance, we’re committed to helping our clients protect what matters most. That includes not only your property and assets, but your personal health and safety. As we head into the warmer months, now is the time to prepare, stay informed, and take steps to prevent heat-related risks.
Heat Can Be Dangerous—and It’s Getting Worse
Last year, Wisconsin experienced its hottest year on record, surpassing even the extreme heat waves of 2012. According to the Wisconsin Department of Health Services, more than 668 people visited emergency rooms in 2023 for heat-related illnesses. Tragically, two heat-related deaths were also reported.
“Heat-related illnesses and deaths are preventable,” said Greg Engle, Administrator of Wisconsin Emergency Management. “It’s important to stay alert to weather conditions and take the steps necessary to keep yourself, your families and pets safe.”
High temperatures—especially when paired with high humidity—can quickly lead to conditions like heat exhaustion or heat stroke. These conditions can be life-threatening if not treated promptly.
Who’s at Risk?
While anyone can be affected by extreme heat, the risk is especially high for:
Older adults
Infants and young children
People with chronic health conditions (heart disease, diabetes, respiratory issues)
Pregnant individuals
Outdoor workers
Those without reliable shelter or air conditioning
Pets
Tips for Staying Safe During a Heat Wave
Whether you’re at home, at work, or enjoying outdoor activities, consider these important safety measures:
Stay in air-conditioned spaces during the hottest part of the day. If you don’t have AC, visit public places such as libraries or cooling centers (dial 2-1-1 to locate one near you).
Keep hydrated by drinking plenty of water—avoid caffeine, alcohol, and sugary beverages.
Limit outdoor activity, especially strenuous work or exercise.
Check in on vulnerable neighbors, friends, and family members.
Never leave children or pets in parked cars, even for a short time. The interior can reach deadly temperatures within minutes.
Protect pets by limiting their time outside, ensuring access to water, and testing pavement with your hand—it’s too hot for their paws if it’s too hot for your skin.
Stay Alert to Heat Warnings
The National Weather Service (NWS) provides several heat-related alerts to help the public prepare:
Heat Advisory – Heat index of 100°F or higher expected
Extreme Heat Warning – Heat index 105°F+ expected, or prolonged heat over several days
Heat Watches and Outlooks – Conditions favorable for extreme heat in the coming days

How This Ties into Insurance
Extreme heat doesn’t just affect people—it can impact property, too. Extended heat waves can lead to:
Increased fire risk
Overworked HVAC systems
Property damage from warping or swelling
Risk of spoilage for refrigerated goods and equipment
Marshfield Insurance encourages all clients to evaluate their homeowners, renters, or commercial policies to ensure they’re adequately covered for weather-related events. It’s also a good time to review business continuity plans and make sure emergency preparedness is part of your family or workplace routine.
