Boston, Massachusetts – Sweltering heat will grip Boston and much of Massachusetts Thursday, July 24, with heat indices soaring near 103°F along I-90 and throughout the city. Relief is finally on the horizon as Friday brings a chance of showers to the region—welcome news after days of unrelenting summer heat.
According to the National Weather Service Boston/Norton office, a Heat Advisory remains in effect for the greater Boston area and surrounding counties from 11 a.m. Thursday until 8 p.m. Friday. Temperatures on Thursday will climb to a scorching 96°F in Boston and nearby cities, while high humidity pushes “feels like” readings well above 100°F. Residents are urged to drink water frequently, seek air conditioning, avoid strenuous outdoor activity, and check on vulnerable neighbors. Never leave children or pets unattended in vehicles.
By Friday night, a 30% chance of showers will sweep into Boston, Worcester, and Cambridge, breaking the heat’s hold but possibly creating slippery roads—especially on major routes like I-90 and Route 128. While not a washout, these spotty showers could offer some cooling relief for outdoor events and those seeking a break from oppressive humidity.
Saturday and Sunday will feel more comfortable, with highs near 81°F and a mix of sun and clouds. Looking ahead, next week brings warm, mostly dry weather—perfect for summer plans, with only a slight chance of more showers late Sunday.
What’s Next:
Heat advisories stay active through Friday. Stay weather-aware and monitor local updates, especially if traveling Friday night as wet roads may follow the late-week rain.
