April 4th in Newtonville sits squarely in the middle of spring's unpredictability — expect a high around 55° and a low near 35°, but history shows anything is possible.

Newtonville's weather has real teeth on both ends — the thermometer has hit 103° as recently as June 2025 and plunged to -11° in February 2023, a jaw-dropping 114-degree spread. A single June day in 1998 dumped 7.15 inches of rain, while the Blizzard of '78 buried the area under 22 inches of snow in one shot. This is a place where the full force of New England weather shows up.
Summer is the sweet spot, with mid-July highs averaging 87° and the warmest stretch running from mid-July through late July.

Rain is fairly consistent year-round, but late summer — especially early August — is the wettest stretch, averaging over an inch of precipitation in a single week.
