Pollen counts peak in April, making it the toughest month for allergy sufferers. Dogwoods and azaleas bloom across the region, and outdoor festivals kick off. Evening temperatures in the 50s–60s are perfect for patio dining and evening walks.
Summer (Jun–Aug)
Hot and humid with highs in the 90s°F and heat indices frequently exceeding 105°F. Daily afternoon thunderstorms develop like clockwork between 2–6 PM, often bringing brief but intense downpours, lightning, and gusty winds. Hurricane season runs June 1 through November 30 — monitor tropical forecasts regularly. Plan outdoor activities for early morning before 10 AM or after 6 PM to avoid peak heat. Hydration and sun protection are essential.
Fall (Sep–Nov)
One of the best seasons in the Southeast as humidity drops and temperatures ease into the 60s–80s°F. Hurricane season remains active through October so stay weather-aware. Fall foliage peaks in the Appalachian mountains during October and in lower elevations through November. Football tailgating, harvest festivals, and outdoor concerts make this prime outdoor season. First frost typically arrives in late October to mid-November.
Winter (Dec–Feb)
Mild compared to northern states with daytime highs in the 45–60°F range and overnight lows in the 25–40°F range. Occasional cold fronts can bring ice storms and freezing rain that shut down roads for days — even a thin glaze causes major disruptions since the region has limited ice-removal equipment. Snow is rare in coastal areas but more common in the mountains. The dry, cool weather makes it an excellent season for hiking, running, and outdoor sports.
