Boston, MA – Residents across Boston and eastern Massachusetts should brace for oppressive heat on Tuesday as temperatures climb toward 94°F, pushing heat index values even higher during the afternoon. The hot, stagnant air will be most dangerous for vulnerable groups and those spending prolonged time outdoors.
According to the National Weather Service, light southwest winds and clear skies will fuel the spike, with the hottest period expected between 1 p.m. and 5 p.m. City cooling centers are expected to see increased traffic, and health officials urge residents to drink water frequently, avoid strenuous activity during peak heat, and check on elderly neighbors.
The heat will break slightly Wednesday as clouds increase and a slight chance of afternoon thunderstorms moves in, bringing a 20% chance of relief. Thursday carries a higher rain potential, with showers and cooler highs in the upper 80s.
This stretch marks one of the summer’s hottest bursts, but cooler, more comfortable conditions should return by Friday. Stay tuned for midweek updates as storm chances develop.
