New Jersey is set to unveil new COVID-19 guidance for summer camps that could include changes to the mask mandate.

State officials are expected to make the announcements on Wednesday. Campers are currently required to wear masks indoors and during certain outdoor activities.

Gov. Phil Murphy said on Monday that the current masks requirements include an exception for excessive heat. But Health Commissioner Judith Persichilli said there is no specific definition of how hot is too hot for masks.

“We need to just trust that they’ll do the right thing and if the kids are suffering from excessive heat, I don’t think there’s a particular marker one way or another,” she said. “The distinction is up to the camps and schools.”

New York Gov. Andrew Cuomo announced on Monday that school districts can decide whether students must be masked outdoors. That discretion does not depend on the temperature.
