Water Temperature on Cape Cod Is A Little Chilly Unless You Know Where To Go

Water Temperature on Cape Cod Varies According To What Side You Are On

It's just not North or South, East or West. But in a way it is.

Most of the beaches that border on Massachusetts Bay are going to be colder than if you are on Buzzards Bay.

The beaches on Massachusetts Bay lie mostly to the North except for Wellfleet which faces West.

The beaches on the Eastern shore of Cape Cod are directly on the Atlantic Ocean. They are pretty cold. Coast Guard Beach is included here. It recently made the top 10 beaches in the world by Dr. Beach. Coast Guard beach was number nine.

Steven P. Leatherman is Director of Florida International University's Laboratory for Coastal Research. He has been putting beaches through their paces for years going back to 1992 and is known best as “Dr. Beach”.

Here is a list of the nation's best beaches according to Dr. Beach:

  1. Hanalei Bay, Kauai, Hawaii
  2. Siesta Beach, Sarasota, Florida
  3. Coopers Beach, Southampton, New York
  4. Coronado Beach, San Diego, California
  5. Hamoa Beach, Maui, Hawaii
  6. Main Beach, East Hampton, New York
  7. Cape Hatteras, Out Banks, North Caroline
  8. Cape Florida State Park, Key Biscayne, Florida
  9. Coast Guard Beach, Cape Cod
  10. Beachwalker Park, Kiawah Island, South Carolina

So there you have it. Coast Guard Beach is one of the nation's best. Pretty good, but it is still a cold water beach.

If you head South we run into the beaches on Nantucket Sound, like the famous Craigville Beach near Hyannis. This water is warmer than the water on Massachusetts Bay or along the Eastern shore and Coast Guard Beach.

Continuing West we come to Woods Hole and Buzzards Bay. This is some the warmest water on Cape Cod. Buzzards Bay funnels the warm eddies that curl off the Gulf Stream. These warm eddies go right up Buzzards Bay driving the water temperature in late August into the seventies. And in the coves at low tide even higher.

You can cross over the Cape Cod Canal at Bourne and follow Route 6 to Wareham and one of the warmest water beaches on Cape Cod.

That beach is Swifts Beach. The water stays warm right through the month of October. The latest I went swimming was on October 14 and the water temperature was just right. Form Water Temperature to Swifts Beach
