Hotter-than-average summer forecast for Asheville and beyond
ASHEVILLE, North Carolina — Tuesday, June 3, 2025, 9:00 a.m. (EDT) — A hot and humid summer is quickly approaching North Carolina, and experts are urging residents to prepare for higher-than-average temperatures, particularly across western parts of the state like Asheville.
Early June brings summer heat right on schedule
According to Corey Davis, Assistant State Climatologist for North Carolina, May provided a short reprieve from intense warmth, but that’s ending. “We avoided a lot of summer-like heat in May,” Davis noted, adding that by early June, the heat will arrive right on time. Typically, Asheville sees average highs in the low to mid-80s°F (around 27–29°C). But this summer, those values are expected to climb well above normal.
Above-normal temperatures projected across North Carolina
The Climate Prediction Center (CPC) has released a 40% to 50% probability that North Carolina will experience above-normal temperatures from June through August 2025. This aligns with broader climate trends indicating that summers are warming across the region.
The Bermuda high, a dominant pressure system influencing the Southeast U.S., is expected to contribute to this warmth by channeling hot, humid air from the south into western North Carolina. Davis noted, “In recent years, we’ve generally run warmer than normal during the summer season.”
Western North Carolina feeling the heat
In Asheville, the annual average includes about 10 to 11 days in the 90s°F (32°C or higher). Last year, the city registered 14 such days, marking a steady upward trend in extreme heat.
This year, the heat coincides with continued recovery efforts from Hurricane Helene, meaning many residents are spending prolonged hours outdoors, making heat-related illness a growing concern.
Public health warnings: know the signs of heat illness
Dr. Ellis Matheson, Public Health Director for Buncombe County, emphasized the importance of recognizing early symptoms of heat stress, including heavy sweating, muscle cramps, and fatigue. Escalating symptoms like nausea, dizziness, rapid heartbeat, and confusion may point to heat exhaustion or heat stroke.
The North Carolina Department of Health and Human Services (NCDHHS) issues Heat Health Alerts when the heat index reaches 94°F (34°C) or higher. The alert system is guided by emergency department data and historical health outcomes, with the goal of targeting vulnerable populations.
At highest risk are older adults, young children, pregnant people, those with chronic illnesses like heart disease, and outdoor workers. “It’s important that they have the right education and access that they need to stay cool,” Dr. Matheson added.
Support for vulnerable groups and community readiness
To mitigate the dangers, the Operation Fan Heat Relief program is active through October 31, 2025, offering free fans to eligible adults aged 60 and over, as well as people with disabilities, via local partners.
Pets are not to be overlooked. “Make sure your dogs, your cats, any outdoor pets can go inside and get cool, as well,” Davis said.
Experts are highlighting hydration, shade, and community check-ins as critical ways to stay safe. “We can all enjoy the season,” Dr. Matheson affirmed, “by recognizing heat illness symptoms, knowing how to respond, and staying connected with neighbors and family.”
