Columbia, South Carolina – Spring 2026 could accelerate quickly across South Carolina, with above normal temperatures increasing the odds of early-season heat before May arrives.
According to NOAA’s Seasonal Temperature Outlook released February 19, South Carolina falls within a broad zone favored for above normal temperatures during March-April-May 2026. The strongest warmth signals stretch across the southern United States, placing the Palmetto State firmly in a region leaning milder than average this spring.
In Columbia and the Midlands, that could mean a faster climb into the 80s by April, along with more frequent warm afternoons in March. Earlier warm spells may also push pollen levels higher sooner, especially as trees and grasses respond to sustained mild air.
Charleston and the Lowcountry are also expected to trend warmer than normal. While coastal breezes may briefly temper extreme spikes, above normal temperatures could lead to an earlier start to beach season by late April and May.
Across the Upstate, including Greenville and Spartanburg, spring warmth may arrive in longer stretches between passing cold fronts. While brief cool shots remain possible, sustained cold appears less likely under the seasonal signal.
In Myrtle Beach and along the Grand Strand, warmer-than-average conditions may support expanding tourism activity earlier in the season.
Overall, South Carolina appears poised for a milder, early-building spring. Residents should prepare for quicker warmups, rising pollen counts and the potential for early heat spikes before summer officially begins.
