Boston’s Monday Weather: Bright Sun, Comfortable Warmth and Clean Air

Take a look outside on Monday and you’ll be greeted by clear, blue skies stretching over the Charles. After a week of patchy fog and the occasional smog‑tainted sunrise, the city finally gets a break – no smoke linger­ing from the distant wildfires that have been drifting eastward all month.

Temperatures will hover comfortably in the mid‑70s (around 24 °C), a welcome rise from the cooler evenings we’ve been dealing with. Morning lows will dip to the upper 50s, so you might still want a light jacket if you’re heading out early for a coffee run.

Humidity will stay modest, hovering near 60 percent, which means the air won’t feel overly sticky. The breezes are expected to be light, coming in from the southwest at 5‑10 mph, just enough to keep the heat from getting oppressive.

Rain? Not a chance. The forecast calls for zero precipitation, and the radar shows a clean picture with no storm systems on the horizon. That translates to a perfect day for a stroll along the waterfront or a bike ride through the Emerald Necklace.

Air‑quality monitors are also reporting a return to “good” levels, with AQI readings back in the 20‑30 range. So if you were keeping an eye on the smoky haze that’s been a concern for commuters and outdoor enthusiasts alike, you can breathe a sigh of relief today.

Looking ahead, the pleasant pattern may stick around through the early part of the week, but forecasters warn that a cold front could roll in later Thursday, bringing a chance of showers and cooler temps. For now, though, enjoy the sunshine—Boston is finally getting the bright, clean day it’s been craving.
