Students in Boston and around New England are beginning class in the middle of what could be a heat wave.
In all, 57,000 students will be returning in 128 different schools in Boston alone, some of which have new principals.
A heat wave is expected in the region, bringing hazy and humid weather, as well as some thunderstorms.
Boston Mayor Marty Walsh and the new superintendent of schools were at Madison Park Technical high School to greet students.
Tommy Chang, who was hired earlier this year as superintendent, comes to Boston from Los Angeles, California, and has already put together a 100-day plan for his department.
Chang says he's an advocate of giving schools the power to make decisions on their own.
Chang said in a statement, "I am asking parents to make sure their children are dressed in weather-appropriate clothing, stay well-hydrated and bring extra bottles of water to school this week. We are ready and excited to kick off a great school year."
