I thought it was just me. Turns out, Charlotte is roasting.
June felt hot. July didn’t let up. And by the time I started sweating through my shirt just walking to get coffee on South Boulevard, I decided to check the data. Short version? You’re not imagining it: summer 2025 is on track to be one of Charlotte’s hottest in a decade.
According to NOAA, our average daily temperature this summer has hovered around 81°F—more than 2 degrees hotter than the typical summer average. If that sounds small, it’s not. In climate terms, it’s a chasm. For reference, the summer of 2016 previously held the record at ~81.3°F. This year’s about to give it a sweaty run for its money.
We’ve already racked up 33 days at or above 90°F, and we haven’t even hit August. Compare that to all of 2023 (49 days total), and it’s clear we’re sprinting toward the top of the heat leaderboard.
Also worth noting: overnight lows this year aren’t giving us much relief. A record-breaking low of 79°F on June 25 shattered our chances for post-sunset recovery. NOAA’s daily reports back this up.

Why It Matters to Charlotte
Extreme heat isn’t just uncomfortable. It stresses our grid, strains our water system, and raises serious health concerns—especially for people who work outdoors or lack air conditioning. When nighttime lows hover in the mid-70s, our bodies get less recovery time.
More troubling: this isn’t an outlier. According to NOAA climate trend reports, summers like this are becoming more common. In fact, Charlotte has steadily added more 90-degree days to its calendar each decade since the 1970s.
That’s not just trivia. It’s policy. When city planning, housing, and public health departments review future infrastructure, this kind of heat must be accounted for.
