Rhode Island weather and outdoor projects
Rhode Island’s coastal climate is moderated by Narragansett Bay and the Atlantic, with cold winters, warm summers and rain throughout the year. Providence is a little colder in winter than the shoreline, which has wind and salt air that wear down finishes.
June and September are often the best months for staining and painting. Sea breezes and morning fog near the coast can delay drying. Nor’easters bring multi-day rain in spring and fall, and hurricanes occasionally affect the state in late summer. Plan concrete work before the first fall freezes.
