Chesapeake, VA Pollen Levels Today

Chesapeake, VA sits in the humid subtropical coastal plain of southeastern Virginia, where mild winters, warm summers, and abundant moisture from the nearby Chesapeake Bay and Great Dismal Swamp create a long, intense allergy season that typically runs from February through October.

Tree pollen kicks things off in late February and peaks from March through April, driven by oak, pine, cedar, juniper, sweetgum, maple, birch, and hickory—loblolly pine in particular coats the region in visible yellow pollen each spring. As trees taper in May, grass pollen rises and dominates from late May through July, with Bermuda, Timothy, orchard, fescue, and Johnson grass being the primary culprits.

Late summer and fall bring weed pollen, peaking from August through October, led by common and giant ragweed, along with pigweed, lamb's quarters, plantain, and sagebrush. The overlap between lingering grass and emerging ragweed in August often intensifies symptoms for multi-sensitive sufferers.

Beyond pollen, Chesapeake's high humidity and proximity to wetlands fuel year-round outdoor and indoor mold growth (especially Alternaria and Cladosporium), while dust mites thrive in damp coastal air. Overall, Chesapeake's allergy profile is defined by a prolonged, pollen-heavy season compounded by persistent mold and humidity-driven triggers.
