Common questions
Is Hopkinton Main Beach in Hopkinton open today?
Hopkinton Main Beach is not monitored right now. MA DPH samples beach water Memorial Day to Labor Day and posts no advisories or all-clears off-season, so there is no swim status to report. Swimming off-season is at your own risk.

Yes, in season, roughly late May through Labor Day.
Are there restrooms at Hopkinton Main Beach?
Public restrooms are listed near the beach. Seasonal hours are common, so they may be closed off-season.

Lifeguards conduct routine water bacteria checks; water presumed safe unless posted otherwise. Pool noodles, boogie boards, and non-coast-guard-approved flotation devices prohibited in swim area.
Can you swim at Hopkinton Main Beach?
