High temperatures will reach the lower 80s inland, while south-facing beaches stay cooler in the 70s thanks to the ocean breeze. The UV index will be high, so be sure to use sunscreen and other sun protection if you'll be spending time outdoors. If you're heading to the South Shore beaches, keep in mind there is a high risk for rip currents, so swim only at beaches with lifeguards on duty and always follow their guidance.
