The cities of Portland and Bangor have announced various locations where people can cool off Saturday, as the state expects high temperatures and humidity.

In Bangor, the parks and recreation department will set up a temporary cooling area — complete with sprinklers — on the Bangor waterfront that will be available from noon to 5 p.m. July 20, according to Tracy Willette, director of the parks and recreation department.

The city’s public swimming pools, The Beth Pancoe Aquatic Center on 13th Street and the Dakin Pool on Pine Street, will be open from 1 to 4:30 p.m.

Down in Portland, The Portland Public Library at 5 Monument Square will serve as the city’s cooling center from 10 a.m. to 5 p.m. Saturday. People can also cool off at the Deering Oaks Ravine, the Kiwanis Pool and other splash ponds around the city, according to Jessica Grondin, director of communications for the city of Portland.

The Portland Expo, which has served as an emergency shelter for more than 250 asylum seekers, has some air conditioning, and the city will be providing a list of places people can visit to cool off.

People are urged to limit outdoor activities, drink plenty of water and wear light-colored clothing.
