(Washington, DC) - Today, Mayor Muriel Bowser is urging residents and visitors to prepare for a heatwave expected to bring triple-digit temperatures to the District beginning today, Wednesday, July 1, and continuing through the Fourth of July holiday weekend. Due to the anticipated high temperatures and humidity levels, Mayor Bowser has activated an Extreme Heat Alert for Wednesday, July 1 through Sunday, July 5, with the possibility of an extension or revision dependent on the forecast. With outdoor gatherings planned across the region over the holiday weekend, residents and visitors should prepare for prolonged heat exposure, drink lots of water - even before feeling thirsty, take frequent breaks in air-conditioned spaces or the shade, and sign up for free weather updates at alert.dc.gov.
The National Weather Service is forecasting daily high temperatures that could exceed 100 degrees at times. When combined with high humidity levels, the heat index is expected to exceed 105 degrees for the next four days, reaching as high as 109 degrees at times. Overnight temperatures are expected to remain above 75 degrees, above the average for this time of year.
When the heat index exceeds 105°F, the District issues an Extreme Heat Alert and deploys additional resources to protect public health. High heat and humidity can quickly lead to heat exhaustion or heat stroke, especially for older adults, young children, people with chronic medical conditions, outdoor workers, and anyone spending extended time outside. Anyone spending extended time outdoors, including at holiday events, should take the heat seriously regardless of how they feel in the moment. Avoid strenuous outdoor activity, especially between 11 am and 4 pm.
Important steps residents and visitors can take to stay safe during extreme heat are:
Residents are also encouraged to check on family members, neighbors, and friends who may be especially vulnerable to extreme heat, including older adults, young children, people with disabilities, and individuals with chronic medical conditions or other access and functional needs.
If you are concerned about neighbors experiencing homelessness, or to request free, accessible transportation to a low-barrier shelter or day center, call the Shelter Hotline at 202-399-7093 or dial 311.
Don't ever leave kids or pets alone in cars because the temperature inside a car can rise very quickly.
If you see an animal left outside or in a vehicle on a hot day, call the Brandywine Valley SPCA at 202-888-PETS.
Signs of Heat Stroke and Heat Exhaustion
It is important for people to recognize the signs and symptoms of heat exhaustion and heat stroke. Symptoms may include heavy sweating, dizziness, nausea, and faintness, as well as more critical signs such as confusion, very high body temperature, rapid heartbeat, lack of sweating, or loss of consciousness. Breathing in hot, humid air can irritate and narrow the airways, making it hard to breathe and may lead to shortness of breath. The onset of heat stroke can be rapid; a person can go from feeling apparently well to a seriously ill condition within minutes.
If you suspect that you or someone you know is experiencing a heat-related illness, call 911.
Cooling Centers
To help residents and visitors stay safe in extreme heat, the District operates free cooling centers across the city. These air-conditioned facilities are located at sites such as community centers and provide a safe space to spend time away from the heat. For hours and locations, visit heat.dc.gov.
Pools, Spray Parks, and Recreation Centers
Spray parks are now open seven days a week, outdoor pools are open six days a week, and both outdoor pools and spray parks will remain open on Friday, July 3, when DC Government observes Independence Day as well as on Saturday, July 4.
Additionally, on Friday, July 3 and Saturday, July 4, the following recreation centers - and three indoor pools - will open as cooling centers, operating from 9 am -5 pm:

The Downtown Day Services Center at 1313 New York Avenue NW will be open on Friday, July 3, from 9 am - 8 pm and Saturday, July 4, from 10 am - 6 pm.
Extreme Heat and Mental Health
Extreme heat can have impacts on a person's mental health, including increased irritability, aggression, symptoms of depression, and the risk of suicide.
If you are prescribed psychotropic medications, stick to your treatment regimen and talk with your doctor about any concerns. Residents who are feeling overwhelmed or showing signs of mental health or substance use disorders can connect with a mental health professional by calling or texting 988 anytime.
Extreme Heat and Aggression
Extreme heat also can affect mood and behavior, contributing to increased aggression, impulsivity, and increased drug/alcohol misuse. Pay attention to your mood and behavior. If you are feeling agitated or irritated, rely on techniques for calming down such as inhaling deeply and exhaling through your nose and walking away from the situation.
And remember: The same steps you take to protect your physical health can also protect your mental health. Staying cool can help you keep your cool.
