Dangerous heat is settling over the New York area, and parts of Long Island could feel almost 100 degrees during the day. With a heat advisory in effect, the conditions are serious enough that schools and local governments are taking steps to protect people from the worst of it. One school district has already decided that the safest option is to get students out of the buildings before the hottest part of the day arrives.
That district is Central Islip, which announced a plan to dismiss students early. Under the plan, high school students are set to be let out around 10 a.m., roughly three hours after they arrive. The early dismissals are then expected to continue throughout the morning across the district's other schools, with the goal of having everyone out by about noon, before the heat inside the buildings becomes too much.
The decision was made with advance notice rather than at the last minute. The district announced the plan a day ahead, giving families time to prepare for the shortened school day. Officials framed the move as an effort to make sure that students, staff and teachers stay safe as temperatures climb.
Other districts across Long Island are taking lighter but still cautious steps. Schools have been asking parents to send their children in with lighter clothing and a water bottle to help them cope with the heat during the day. The guidance reflects a broad concern across the region about keeping young people comfortable and hydrated.
The response is not limited to schools. Nassau County is opening four cooling centers because of the heat, giving residents a place to escape the high temperatures. Such centers are a common tool during extreme heat, offering air-conditioned spaces for anyone who needs relief from the conditions outside.
The way schools handle the heat is shaped by a state law. Governor Kathy Hochul signed legislation in 2024 to protect students and teachers from extreme heat, and that law set 88 degrees as the maximum temperature a classroom can reach. Once a room hits that level, students either have to be moved to a cooler area or dismissed, which helps explain the kind of decision Central Islip made.
The same law also sets an earlier trigger for action. Districts are required to take steps to relieve heat related discomfort when classroom temperatures reach 82 degrees, well before the 88 degree ceiling. Combined with the heat advisory and concerns about poor air quality, those rules are driving how Long Island schools are responding to a day of dangerous heat.
