A period of dangerous heat and humidity is expected from Wednesday through Friday. Daytime high temperatures in the mid-90s to near 100°F, combined with high humidity, could produce heat index values of up to 110°F. Overnight temperatures will remain warm and muggy, providing little relief from the heat.

Cooling Centers

The City of Newburyport will have three cooling centers available for residents:

Newburyport Public Library (94 State Street) – Open during regular business hours (9 a.m. - 9 p.m.) on Wednesday and Thursday.

Newburyport Senior/Community Center (331 High Street) – Open during regular business hours (8 a.m. - 4 p.m.) on Wednesday and Thursday.

Newburyport Salvation Army (40 Water Street) – Open daily from 8:30 a.m. to 4:00 p.m. If temperatures remain in the 90s after 4:00 p.m., the center will remain open until 9:00 p.m. The Salvation Army will also provide lunch and dinner for all guests.

Stay Safe During the Heat

Please take the following precautions:

Drink plenty of water and stay hydrated.

Limit outdoor activities during the hottest part of the day.

Spend time in air-conditioned buildings whenever possible.

Check on elderly neighbors, family members, and others who may be vulnerable to extreme heat.

Visit a cooling center if you need a safe, air-conditioned place to escape the heat.
