With the D.C. region facing scorching heat through this weekend, Fairfax County is adjusting its holiday closure plans to allow for a 24-hour cooling center at the Jim Scott Community Center in Oakton.
On top of previously announced alerts for today and tomorrow (Friday), the National Weather Service has issued another Extreme Heat Warning for the region on the Fourth of July, predicting potential heat index values of up to 113.
All of the warnings are currently scheduled to be in place from 10 a.m. to 8 p.m. each day.
The combination of heat and humidity is expected to exacerbate air pollution created by the massive fireworks show planned for July 4 in D.C., creating “very unhealthy” conditions in the nation’s capital and closer suburbs like Arlington County, the Washington Post reported based on internal National Park Service documents.

Fairfax County has activated its heat plan through Saturday, but cooling center options will be more limited tomorrow and Saturday, when most public facilities, including libraries and community centers, will close in observance of the Fourth of July holiday.
However, the county government announced today that the Jim Scott Community Center (3001 Vaden Drive) will serve as a 24-hour cooling center, remaining open until 8 a.m. on Sunday (July 5).
“This overnight location was activated to ensure residents have access to a cool, safe place throughout the Fourth of July holiday weekend, when many regular county buildings may be closed,” the county said in an emergency blog post.
Regular programming will still end for the week at 10 p.m. today, like at other community centers. Residents seeking transportation to or from the Jim Scott center can call 703-865-0520.
Because of the continued extreme heat expected through the holiday weekend, the county has activated a 24-hour cooling center at the Jim Scott Community Center.
The county’s heat plan has also been extended through Saturday, July 4.

In addition, the county’s rec centers will still be open tomorrow and on Saturday, albeit for shortened hours:
July 3
- All Rec Centers (except for George Washington) are open from 5 a.m.-9 p.m.
- George Washington Rec Center is open from 6:30-11:30 a.m.
July 4, 2026
- All Rec Centers (except for George Washington) are open from 7 a.m.-4 p.m.
- George Washington Rec Center is open from 9 a.m.-4 p.m.
According to the county, its three emergency shelters for adults — the Bailey’s Shelter in Bailey’s Crossroads, Eleanor U. Kennedy Shelter in Fort Belvoir and Embry Rucker Community Shelter in Reston — are also accommodating overflow capacity both during the day and at night in response to the heat wave.
“Cooling centers will … have supplies available including bottled water, sunscreen, insect repellent and body wipes,” the county said. “During extreme heat, facilities may have unexpected closures due to HVAC issues so please verify that the location is open.”
Reston Regional Library, for instance, has closed for today “due to an HVAC issue,” according to Fairfax County Public Library. Hunter Mill District Supervisor Walter Alcorn recommended visiting the nearby North County human services building at 1850 Cameron Glen Drive instead “if you need a place to get cool.”
Concert cancellations, waste pickup changes
The ongoing heat wave has prompted cancellations of a couple of outdoor concerts planned for tonight, including the U.S. 257th Army Band’s 5:30 p.m. performance at the Fairfax County Government Center.
Timed to usher in the Independence Day holiday weekend, the concert would’ve served as the kick-off to Fairfax County Board of Supervisors Chairman Jeff McKay’s Evenings on the Ellipse — one of 10 series included in the Summer Entertainment Series organized annually by the Fairfax County Park Authority and supervisors’ offices.
Show Update: The United States 257th Army Band performance scheduled for 7/2 at the Fairfax County Government Center is cancelled due to extreme heat conditions.

“[The] concert has been canceled to help protect the health and safety of attendees, performers, volunteers, and staff,” McKay said in a message to newsletter subscribers this morning. “While I know many residents look forward to this popular event as part of the Fairfax County Park Authority’s free Summer Entertainment Series, public safety must always come first during periods of dangerous heat.”
Evenings on the Ellipse will instead start next Thursday, July 9 with the rhythm and blues/hip-hop group Mature Clientele.
Tonight’s performances by the Eric Scott Trio at Nottoway Park in Vienna and Anthony “Swamp Dog” Clark at Frying Pan Farm Park in the Herndon area have also been nixed, the park authority said in an alert.
In addition, the McLean Community Center has canceled “Still Surfin’: A Tribute to the Beach Boys,” which was slated to take place at 7 p.m. at the McLean Central Park amphitheater as a commemoration of America’s 250th anniversary. The center’s free Summer Concerts at the Park will instead continue on July 9 with One Hit Wonders.
Other impacts of the heat have included closures of Fairfax County Public Schools grounds to outdoor activities and a delay to the start of Vienna’s Independence Day Celebration, which has been pushed from 6 to 8 p.m. Fireworks are still expected to begin around 9:30 p.m., but attendees will have less time to enjoy live music, food trucks and other pre-show activities.
Fairfax City facilities will be closed both tomorrow and on Saturday, but the city’s Green Acres Center (4401 Sideburn Road) is serving as a cooling center until 8 p.m. today.
The city has also suspended yard waste, brush and debris collections for today, so pickups won’t resume until Monday, July 6.
To reduce health risks related to the heat for its sanitation workers, the Town of Vienna is continuing to ask residents to leave trash and recycling bins at the curb by 5 a.m. so crews can collect them early. The revised schedule will continue through Monday.
Temperatures are projected to remain in the upper 90s at least through the end of this week before slightly cooling off to a high of “just” 90 degrees on Monday following possible showers Sunday night.
