WASHINGTON (TNND) — Despite a heat wave that blanketed the eastern U.S. with high temperatures and stifling humidity, Americans took part in Fourth of July festivities on Friday.

Still, many celebrations were scaled back or canceled due to the extreme heat.

 

Cities from the Mid-Atlantic to New England shortened parades, moved events to cooler hours, and adjusted schedules in an effort to protect attendees, as well as volunteers and emergency personnel. Some communities canceled outdoor festivities altogether, citing public safety concerns.

The Great American State Fair temporarily closed on Friday due to extreme heat conditions in Washington, D.C. Freedom 250 said the fair gates will reopen at 5 p.m. EST for evening events.

"The safety and well-being of our guests, volunteers, performers, vendors, and staff is our highest priority. Conditions are expected to improve later this afternoon, and we look forward to welcoming everyone back at 5:00 p.m. as preparations continue for this evening’s festivities," Freedown 250 wrote on X.

The National Weather Service issued excessive heat warnings and advisories for millions of people, warning that prolonged exposure could increase the risk of heat-related illnesses, particularly for older adults, young children, and people with underlying health conditions.

Officials urged residents planning to attend fireworks displays, festivals, and community gatherings to stay hydrated, seek shade when possible, and limit strenuous outdoor activity during the hottest parts of the day.

Some organizers have expanded access to cooling stations, misting tents and free drinking water, while others have encouraged attendees to arrive later in the evening when temperatures begin to fall.
