Cape Cod Weather
Because Cape Cod stands guard offshore from the New England land mass, swaddled in both cold and warm waters, its weather is unique to the region.
In winter the Cape is warmed by the ocean and in summer it is cooled by those same waters. It is rare during even the sultriest summer day for there not to be a cooling ocean breeze. Incidentally, at one time, there were more than 1,000 windmills lining the shores of Cape Cod, availing themselves of the prevailing winds to grind grains and power pumps for salt works. Similarly, when the balance of New England is painted white by snow, a true snowfall is rare on Cape Cod. Once again, the oceans work their magic in maintaining the Cape’s rather temperate climate.
Spring, fall and even some winter days are ideal times for recreation and outdoor pursuits, including golf, as the weather stays relatively mild all year long. The most pleasant temperatures can be found in the months of May, June, September and October. July is on average the warmest month, and January is on average the coolest month.
