Current ocean temp at every beach — updated all day long
Cape Cod ocean temperatures vary more than most visitors expect — Bay-side beaches in Barnstable and Dennis can run 5–10°F warmer than the ocean-facing National Seashore beaches in Eastham or Wellfleet, especially in summer. This page shows the current water temperature at every beach in our live data feed, so you can find the warmest swim of the day before you leave the house.
