Expect Many More Days to Feel Like 100 Degrees: Study

By the middle of this century, parts of New England will see a dozen or more days that feel like at least 100 degrees, according to a study published this week by the Cambridge-based Union of Concerned Scientists.

The “feels like” temperature in the summer, also known as the heat index, is calculated by combining the actual temperature and the humidity.

This weekend, for example, temperatures will reach the upper 90s to near 100. When you factor in dew points over 70, which represents oppressive humidity, the heat index will be in the 100-110 range.

While there are occasionally days that feel like 100 degrees during the summer in New England, the average of those type days each year, for each New England state, is currently zero.

Below you will find a summary of what to expect in each New England state as temperatures and humidity continue to climb, as this study projects, assuming greenhouse gas emissions stay steady.
