Typically, Boston experiences a transition from summer to autumn during late September. Average high temperatures generally fall from the low 70s Fahrenheit (low 20s Celsius) at the beginning of the month to the mid-60s Fahrenheit (high teens Celsius) by the end. Overnight lows correspondingly decrease from the mid-50s Fahrenheit (low teens Celsius) to the mid-40s Fahrenheit (single-digit Celsius). Rainfall amounts are usually moderate, and humidity begins to lessen. This period marks the start of the foliage season in the surrounding New England region.
Understanding Boston’s climatological norms for this period is crucial for planning visits. Comfortable temperatures facilitate outdoor activities, from exploring historical sites to enjoying the city’s parks. The changing foliage adds a scenic dimension to the urban landscape, making it an attractive time for tourism. Historically, this transitional season signifies the shift from the bustling summer months to the quieter autumnal period, allowing residents and visitors alike to experience a different side of the city.
