D.C.’s public coronavirus testing sites will operate on a “modified schedule” Tuesday and Wednesday due to extreme heat.

Each day, two public testing sites will be open for three hours in the morning, from 8-11 a.m. when it’s expected to be slightly cooler. (Public testing sites like the Judiciary Square and Anacostia locations are usually open from 10 a.m. – 2 p.m.)

All of the walk-up testing locations at firehouses, which usually operate in the late afternoon and evening, will be closed.

The mayor’s office said residents “are still encouraged to call their health care providers if they are in need of a test.”

Below are the sites that will be open Tuesday and Wednesday:

Tuesday, July 21:

• UDC-CC Bertie Backus testing site, 5171 South Dakota Avenue NE (8-11 a.m.)
• Judiciary Square testing site, F Street NW between 4th and 5th streets NW (8-11 a.m.)

Wednesday, July 22:

• Anacostia testing site, 2241 Martin Luther King Jr. Avenue SE (8-11 a.m.)
• Judiciary Square testing site, F Street NW between 4th and 5th streets NW (8-11 a.m.)

The District suspended testing at all city-run sites Monday as temperatures peaked in the upper 90s, and the heat index stretched into triple digits.

Testing in the city’s congregate facilities has not been affected, said Christopher Rodriguez, director of the D.C. Homeland Security and Emergency Management Agency. He added that coronavirus antibody testing, which happens inside, is also still available.

Rodriguez said officials made the decision to suspend, and now modify, public testing out of concern for the people getting testing and those running the sites.

“We want to make sure that, again, when the temperature is at its almost peak, that our personnel who are staffing the sites … who are in full PPE when they’re administering the tests, are doing so in a safe way,” he said, “We also have seen a lot of demand for our testing sites. So making sure that residents in lines are not putting themselves at risk for the heat.”

Officials will continue to monitor the weather, but Rodriguez said testing sites may be able to resume their normal schedules on Thursday.

On Monday, D.C. closed its grocery distribution site due to the heat, but they will reopen Tuesday with normal hours. Grocery distribution and meal site locations and hours can be found here.

Mayor Muriel Bowser has activated the District’s heat emergency plan. Whenever the temperature or heat index is 92 degrees or higher, the city operates cooling centers at several public schools, recreation centers, and homeless shelters. An interactive map of locations is available here.

During this heat wave, local officials encourage everyone to stay hydrated and limit their time outside.
