Delaware – The Delaware Division of Public Health (DPH) reminds residents to take precautions as the state continues to experience an extreme heat wave through Monday, June 23rd, 2025, and the days ahead. The National Weather Service reports sustained high temperatures and dangerous heat conditions across Delaware.
While all residents face some risk, infants, young children, older adults, pregnant individuals, and pets remain most vulnerable. Infants and children require extra care since they cannot always communicate when overheated or dehydrated. Adults 65 and older may be less able to adapt to sudden temperature changes due to health conditions or medications. Pregnant people face increased risk because their bodies work harder to cool themselves and their babies. Pets with dark coats, those very young or elderly, and those with health concerns also need protection.
People who work outdoors, have chronic illnesses, or lack access to air conditioning or cool shelter are at greater risk. Checking on neighbors and loved ones in these groups is recommended.
DPH advises residents to stay cool by using air conditioning or visiting local cooling centers, wear lightweight, light-colored clothing, limit outdoor activities during peak heat hours, and drink plenty of water. Avoid sugary or alcoholic beverages, and never leave children or pets unattended in vehicles, where temperatures can quickly become life-threatening.
For daily heat updates, residents can consult the CDC and National Weather Service heat trackers.
