Boston, Massachusetts – A refreshing pattern change is headed to New England, bringing below-normal temperatures as July ends and August begins. By Friday, cooler air from Canada will settle in, providing much-needed relief after recent heat waves.
According to the National Weather Service, a surge of Canadian air will move southward from July 30 to August 5, 2025, causing high temperatures to stay several degrees below seasonal averages across Massachusetts, Maine, New Hampshire, and Vermont. Early forecasts suggest that cities like Boston, Portland, and Burlington will experience afternoon highs in the upper 60s to low 70s—nearly 10 degrees cooler than typical August days.
For residents and travelers, the cool-down may provide welcome relief, but it could also bring chilly nights, particularly in interior areas and higher elevations. Light jackets or extra layers may be necessary for morning commutes, hikes, or coastal outings. Outdoor enthusiasts should also be aware of the increased risk of patchy fog and damp mornings, especially along the I-95 corridor and near the Green and White Mountains.
This cool spell marks the first significant August cool-down since 2021, and it may persist through the first full week of the month. Stay tuned for local weather updates for any advisories or rapid changes, especially as summer events and travel continue.
