Grantham opens Town Hall cooling space during extreme heat
Grantham opened the lower level of Town Hall as a cooling space while heat index values climbed as high as 109. The town listed hours, but not who can use it after 5 p.m.

Grantham opened the lower level of Town Hall as a cooling space Thursday, giving residents a place to get out of dangerous heat at 300 Route 10 South. The municipal calendar listed the space as open from 9 a.m. to 5 p.m., but it did not say who could use it, whether there were any entry rules, or where people should go if the heat continued after closing.
The move came as the National Weather Service had an Extreme Heat Watch in effect for the Grantham area from July 1 at noon through July 3 at 8 p.m., with forecast highs around 98 on Wednesday, 102 on Thursday and 100 on Friday. The weather service also warned that heat index values could reach 109 on Wednesday before upgrading the area to an Extreme Heat Warning by the evening of July 2, through Friday evening.
New Hampshire health officials have said extreme heat can cause heat exhaustion and heat stroke, with older adults, young children and people with chronic diseases facing the highest risk. The New Hampshire Department of Health and Human Services advises residents who do not have a cool place to go to call 211 for a listing of air-conditioned cooling centers, and its community heat toolkit says people should find an air-conditioned shelter, not rely on a fan as the primary cooling device, and check on those most at risk twice a day.
The town’s one-room opening offered a practical response for a rural community where a quick trip to Town Hall can be easier than finding another cooled building in the middle of a heat wave. It also raised a basic question of preparedness: whether Grantham has a broader extreme-heat plan or is depending on an improvised response tied to the day’s forecast and the Town Hall calendar.
New Hampshire’s Division of Homeland Security and Emergency Management had already posted an extreme-heat caution notice on June 30, adding to the public safety warning facing Sullivan County and the rest of the state. The National Center for Healthy Housing also lists cooling centers as a standard response during extreme heat, underscoring the role public buildings can play when homes do not offer safe relief from the temperature.
