About pollen in Charleston

Weed pollen is the most active contributor to the air in Charleston today, though it remains at a low level overall. Tree and grass pollen are both minimal and should go largely unnoticed. Most people, including those with sensitivities, should find today comfortable with little to no irritation. Looking ahead, conditions are expected to stay fairly steady over the next several days, with tree and grass pollen holding at very low levels throughout. Weed pollen may tick up slightly mid-week before settling back down, reflecting the tail end of ragweed season, which typically lingers into fall in the Lowcountry. Tree pollen from oaks, pines, and other regional species remains dormant this time of year and won't become a factor again until spring.
