Boston, MA – Unseasonable summer heat will grip eastern Massachusetts on Tuesday, June 3rd, as temperatures soar to 86°F under sunny skies and hazy air. Commuters along I-93 and I-95 should prepare for visibility issues from smoke drifting south from Canadian wildfires — a health risk that may trigger air quality alerts.
According to the National Weather Service, calm conditions in the morning will give way to southwest winds around 5 mph by afternoon, combining with lingering haze to create potentially poor breathing conditions for sensitive groups. Tuesday’s heat marks one of the highest readings so far this June, with a notable jump from Monday’s more comfortable 73°F high.
By Tuesday night, temperatures drop to 57°F, with mostly clear skies and light winds. The summerlike pattern continues through midweek, with Wednesday, June 4th, bringing another sunny day and a high near 86°F. Air quality could remain a concern depending on the wildfire plume’s position.
Residents should limit outdoor activity during peak heat and poor air quality hours. Hydrate frequently and check on elderly neighbors or those with respiratory issues.
Looking ahead:
- Thursday (June 5): Hot again, 90°F and partly cloudy.
- Friday (June 6): Showers after 2 p.m., high of 85°F.
- Saturday (June 7): Continued chance of rain, high near 79°F.
- Sunday (June 8): Mostly sunny, high near 76°F.
