If Tuesday's heat felt unbearable, you're not imagining it. Boston hit 102 degrees, the hottest June day in the city since 1872, according to the National Weather Service. That kind of heat is incredibly rare in New England,

The thermometer at Boston Logan International Airport showed 102 degrees as of 5:23 p.m. Tuesday, according to the National Weather Service’s Boston office. The 102-degree reading set the record for the hottest ever June temp in city history. It broke the previous 100-degree June days in 2021, 1952, and 1925.

A heat wave will intensify along the East Coast this week as tropical humidity levels and 100-degree temperatures reach big cities from Boston to Washington. On Sunday, humidity levels were higher in parts of the Northeast and southern Canada than in Florida,
