Maryland Extreme Heat Safety: How To Stay Safe During The Hottest Summer Days

CALIFORNIA, Md. — Extreme summer heat is a regular part of life in Maryland. Whether you live in Southern Maryland, Anne Arundel County, the Baltimore area or Washington, D.C.’s nearby suburbs, high temperatures combined with heavy humidity increase the risk of heat exhaustion and heat stroke, even for healthy adults. Learn the simple steps that can help keep you, your family and your pets safe, recognize the warning signs of heat-related illness and find out where to cool off when temperatures soar.

Why Maryland’s Heat Can Be Especially Dangerous

Air temperature tells only part of the story. Humidity plays a major role in how hot conditions feel because it makes it harder for sweat to evaporate and cool the body. That is why weather forecasts often highlight the heat index rather than the air temperature alone.

During periods of prolonged heat, the body works harder to maintain a safe internal temperature. Older adults, infants, young children, people with chronic medical conditions and those who work or exercise outdoors often face higher risks. Even healthy adults can become ill if they spend too much time outside without adequate water or rest.

Residents across St. Mary’s, Calvert and Charles counties, as well as Anne Arundel County and other parts of Maryland, should pay close attention to local weather forecasts during the warmest months.

What Are The Signs Of Heat-Related Illness

Recognizing symptoms early can prevent a medical emergency.

Heat stroke is a medical emergency. Warning signs can include confusion, loss of consciousness, very high body temperature, hot skin or seizures. Anyone showing signs of heat stroke should receive immediate medical attention.

Do not ignore symptoms simply because they seem mild. Heat illness can worsen quickly, especially during periods of prolonged exposure.

Stay Hydrated Throughout The Day

Drinking enough fluids is one of the most effective ways to reduce heat-related risks.

Water is generally the best choice for most people. Try to drink regularly throughout the day rather than waiting until you feel thirsty. If you are spending time outdoors or performing physical labor, you may need more fluids than usual.

Alcohol can contribute to dehydration, and some beverages with large amounts of sugar or caffeine may not be the best option during extreme heat.

People with certain medical conditions or fluid restrictions should follow guidance from their health care provider.

Plan Outdoor Activities Carefully

Summer in Maryland brings beach trips, boating, youth sports, festivals and yard work. Timing can make a significant difference.

When possible, schedule strenuous activities during cooler morning or evening hours. Take frequent breaks in shaded or air-conditioned locations and wear lightweight, loose-fitting clothing.

Use sunscreen to reduce the risk of sunburn, which can make it more difficult for the body to regulate temperature.

If temperatures or humidity become unusually high, consider postponing nonessential outdoor work until conditions improve.

Tips For Outdoor Workers

Construction crews, landscapers, farmers, delivery workers and others who spend long hours outside face additional challenges during Maryland summers.

Employers and workers benefit from planning ahead. Regular water breaks, shaded rest areas and monitoring coworkers for signs of heat illness can improve safety. Workers who are new to physically demanding outdoor jobs or returning after time away may need time to gradually adjust to hot conditions.

Anyone working outside should report symptoms of heat illness immediately rather than trying to work through them.

Cooling Centers Can Provide Relief

During periods of extreme heat, local governments may open cooling centers or designate public buildings where residents can escape dangerous temperatures.

Cooling centers may be available in locations such as libraries, community centers or other public facilities depending on local plans. Availability varies by jurisdiction, so residents should check with their county or municipal government for current information.

If your home does not have reliable air conditioning, spending several hours in a cool public building may help reduce heat-related risks.

It is also a good idea to check on neighbors, especially older adults or anyone who may have limited mobility or limited access to air conditioning.

Protect Children, Older Adults And Pets

Never leave children, older adults or pets inside a parked vehicle. Interior temperatures can rise rapidly even when outside temperatures seem manageable.

Children should take regular breaks from outdoor play, drink water frequently and spend time indoors during the hottest parts of the day.

Pets also need plenty of fresh water and shade. Walk dogs during cooler parts of the day when sidewalks and pavement are less likely to become dangerously hot.

Prepare Before A Heat Wave Arrives

A little preparation can make extreme heat easier to manage.

Keep bottled water available, make sure fans and air conditioners are working properly and identify nearby public places where you can cool off if needed. Charge mobile devices before severe weather or power disruptions and pay attention to local forecasts and public safety announcements.

Families should also have a plan for checking on relatives or neighbors who may need extra assistance during prolonged hot weather.
