Waltham Weather Outlook: June 26 to July 4

Relief is here. A backdoor cold front has swept through the region, dropping temperatures and humidity dramatically across Waltham. The transition from oppressive to refreshing is already underway, with highs in the 70s for several days. Expect low clouds, onshore breezes, and occasional showers as cooler marine air dominates.

Heading into next week, the pattern flips again as warming resumes by Sunday with 80s returning, and the potential for thunderstorms increases.

The first days of July may flirt with summer heat again. Looking ahead to Independence Day, an early read suggests warm and mostly sunny weather for July 4th in Waltham, great for outdoor plans, however as of this writing it’s still several days out, so we will keep you posted if there are any significant changes.
