Summer water temperature

Is there a big difference between the bay side and the sound side (Dennisport)?

Yes, the bay side is cooler than the sound side. It also has tidal flats at low tide that will warm up some tidal pools considerably though. Little kids like playing and splashing around in them.

Bay side is not as cold as the Atlantic (National Seashore) side though.

The answer could be yes or no. The biggest difference is between Nantucket Sound waters(Dennisport) and the Atlantic beaches where the waves are fun, the temp is bone-chilling cold,kids are shivering and surfers are wearing wet suits.

I would recommend experiencing all of these beaches however (Mayflower on the bayside at low tide is easy to reach from Dennisport) during your vacation.

If you want to see a comprehensive 'discussion' of the Cape Cod beaches look back a ways on this forum for one topic that has something like 80 posts on it.

Check this link for general beach info and some water temps:


Nantucket Sound beach waters can be a bit chilly, Cape Cod Bay waters are cold and the Atlantic is Really cold. The younger you are the less you notice the difference! ;)

It depends on who you ask! I grew up on the bay side which I always thought was plenty warm (would often go for an evening dip). We would occasionally go to the Ocean side (Nauset Beach) where a toe in the water would take your breath away as it was so chilly(it "warms up" by mid-august and reaches a "balmy" 64*). However, my husband who grew up on the sound side thinks the bay side is freezing! I have found the sound side to get to low 70's and be quite comfortable. We even went swimming in the sound in October this year! Although, seeing you are from Jackson, I would say if you frequent Echo Lake at all, you will be fine at either the sound or the bay side.

Here is a link for Falmouth beaches.


It seems that the avg. water temp is a balmy 70 degrees. Most Falmouth beaches have low water inlets where the kids can scoop up little critters with nets, esp. Old Silver, Woodneck and Menhaunt beaches. Windy days bring out the kite surfers at Chappaquoit(Chappy) and Old Silver. Great sunsets there as well!
