I've heard that you can see harbor seals easily from shore around this time of year, somewhere around North Kingston? Maybe someone here will know more.

Just Googled: "Rome Point in North Kingstown, Brenton Point in Newport, Rocky Point in Warwick, and Church Cove and Usher Cove in Bristol are what Lewis calls “sentinel sites” that tend to have the highest number of seals during each low tide and are usually occupied early and late in the season."

Save the Bay also has seal watching boat tours; don't know anything about those or if they are offered now.
