For the week of July 21, high temperatures in the mid-70s to mid-80s are expected, with some showers and thunderstorms forecasted by the National Weather Service.
As a northeastern Massachusetts town, Wellesley’s traditional weather has been characterized by four distinct seasons.
Winter: Cold and snowy, with average temperatures ranging from the low 20s to mid-30s°F. Snowfall is most common from December through March.
Springs: Mild to warm, with temperatures gradually rising from the 40s in March to the 60s and 70s by May. Rainfall is frequent, making the scheduling of baseball, softball, and other outdoor activities unpredictable.
Summers: Warm to hot and humid, with average highs in the upper 70s to mid-80s°F. July and August are typically the hottest months, though many Wellesley residents wouldn’t know it—they leave for their summer houses, or those of friends with summer houses.
Autumns: Cool and crisp, with temperatures decreasing from the 70s in September to the 40s by November. This season is marked by vibrant fall foliage, which shows off for incoming college students in town, and many consider it their favorite season.
