Always bring plenty of water and wear lightweight clothing.

๐Ÿงบ Enjoy Dinner Outdoors

Skip cooking inside and enjoy an evening picnic once the temperatures begin to drop.

Local parks make wonderful dinner destinations.

๐ŸŒ… Stay Out for Sunset

Finish the day by watching the sunset together.

Extreme heat can become dangerous quickly, especially for young children.

Keep these tips in mind:

  • Drink water frequently.
  • Wear lightweight, light-colored clothing.
  • Take frequent breaks in the shade or air conditioning.
  • Never leave children or pets in a parked vehicle.
  • Limit strenuous outdoor activity during the hottest part of the day (typically between 11 a.m. and 4 p.m.).
  • Use sunscreen and wear hats when outdoors.

Make the Most of Summer—Even During a Heat Wave

A heat wave doesn't have to put a damper on family fun. The Merrimack Valley is full of opportunities to stay cool while making lasting memories together. Whether you're discovering a new library program, cooling off with a scoop of ice cream, splashing in the water, or exploring an indoor attraction, there are plenty of ways to enjoy the season safely.
