Extreme Heat Days in Maine Are Happening More Than Ever

It isn't just the average temperature that has steadily risen over the last decade plus, it's also the extreme heat days becoming more prevalent.

According to WGME, days of extreme heat have begun happening in Maine more frequently. That has leading to a heavier reliance on air conditioning which not only cost Maine people money but puts pressure on an already fragile power grid.

Many of those extreme heat days have also brought increased dew points. Humidity has always been an issue during Maine summers but over the last decade, the humidity has moved into the 'oppressive' category far too often.

Maine has averaged a daytime high in July of 79 degrees over the last 5 years.
