Boston is in for a wild weather swing this week as the city transitions from mild, spring-like temperatures to a sharp return of winter’s chill by the weekend. After enjoying highs in the low 50s for much of the week, Bostonians should prepare for a 30-degree drop, with freezing temperatures expected by Sunday.
This rapid shift is caused by a cold front sweeping across the Northeast, bringing breezy conditions, rain showers, and much colder air. By Sunday, temperatures will struggle to climb above freezing, with lows dipping into the teens for the first time in weeks.
What’s Behind Boston’s Sudden Temperature Drop?
Boston’s mild midweek temperatures are thanks to a brief warm air surge moving up the East Coast. However, this warm spell will be short-lived. By Friday, winds will pick up, ushering in colder Arctic air from Canada. The change will be dramatic, with Saturday bringing afternoon rain showers and Sunday feeling bitterly cold as temperatures plunge to 18°F (-8°C) overnight.

What This Means for Boston Residents
If you’ve been enjoying the milder, spring-like temperatures, brace yourself—winter is coming back fast. Friday will be the turning point, as gusty winds make it feel even colder than the thermometer suggests.
For those planning outdoor activities, Saturday will be the last relatively comfortable day before the deep freeze sets in. Sunday will be a wake-up call, with icy winds, freezing temperatures, and a reminder that winter isn’t over yet.
Looking Ahead: Is This the Last Cold Snap for Boston?
While the early part of March is expected to bring slightly milder conditions, Boston’s unpredictable late-winter weather means more temperature swings could be on the horizon. The long-range forecast suggests that temperatures may climb back into the 40s by early next week, but another cold spell isn’t out of the question.
