Is it allergy season in West Virginia?

West Virginia's Appalachian terrain creates a paradox: the mountains are beautiful but the hollows and valleys that wind between them act as natural pollen traps. West Virginia sits in the heart of the Central Appalachian hardwood belt — arguably the most biologically diverse temperate forest in North America — with over 100 tree species producing pollen. Narrow valleys between ridges allow pollen to accumulate on still days. Spring pollen seasons are intense and the diversity of species means overlapping waves of different allergens throughout April and May.

West Virginia's allergy profile is shaped by elevation and terrain more than any other factor. Lower elevation river valleys — the Ohio, Kanawha, and Monongahela corridors — see the earliest spring pollen and the most intense ragweed, as valley walls trap pollen on still days. Higher elevation areas in the Highlands experience a compressed season that arrives 2–3 weeks later but still peaks intensely.

Charleston / Kanawha Valley

River valley trapping in the state capital

Charleston sits in the Kanawha River valley, where the river's corridor concentrates pollen between the surrounding ridges. The state capital experiences some of the earliest spring tree pollen in the state. Oak, maple, and tulip poplar overlap in a dense April–May window. Ragweed in the valley is significant.

Huntington / Ohio River

Tri-State convergence and Ohio River humidity

Huntington sits at the Ohio River where West Virginia, Kentucky, and Ohio meet. The broad Ohio River valley allows pollen from three states to accumulate. Spring tree season is heavy with oak and maple. Ragweed counts in the Ohio River corridor are significant, influenced by Kentucky and Ohio patterns.

Morgantown / Mon Valley

University town in a deep Appalachian valley

Morgantown occupies the Monongahela River valley surrounded by steep Appalachian ridges. The valley geography creates one of the state's most concentrated pollen environments. Dense birch and oak forests on surrounding hills produce heavy spring pollen. WVU students experience an intense April tree season.

Eastern Highlands

High elevation — late but compressed season

The Allegheny Highlands in Pendleton, Pocahontas, and Randolph counties sit above 3,500 feet elevation. Spring pollen arrives 2–3 weeks later than the western valleys. The compressed season means intense peaks in May–June. Ragweed is lighter at elevation. This area offers the state's longest relief window.

Each row shows a full year of pollen for one region — trees in blue, grasses in green, weeds in amber. Look for where all three rows go quiet at the same time — that's your window.

Oral Allergy Syndrome (also called pollen-food allergy syndrome) causes tingling or mild itching in the mouth when you eat certain raw foods during the relevant pollen season. The proteins in the food are similar enough to the pollen protein that your immune system cross-reacts. Cooking usually deactivates the offending protein, so the same food cooked may cause no reaction.

Birch & Oak pollen

Stone fruits, apples & nuts

Apples, peaches, cherries, plums, pears, almonds, hazelnuts, carrots, celery, parsley

Peak risk April–May in West Virginia. The Appalachian hardwood belt's exceptional birch and oak diversity makes WV one of the highest-OAS-risk states in spring. Birch cross-reactivity is particularly broad — reacting with more foods than oak alone.

Grass pollen

Tomatoes, potatoes & melons

Tomatoes, potatoes, kiwi, watermelon, cantaloupe, oranges (in some cases)

Peak risk May–July. Timothy and orchard grass are the dominant grasses in WV's valleys and fields. Pollen concentrates in the narrow hollows between ridges.

Ragweed

Melons & bananas

Watermelon, cantaloupe, honeydew, banana, zucchini, cucumber, sunflower seeds

Peak risk August–October. The Ohio and Kanawha River valleys trap ragweed pollen effectively. Huntington and Charleston experience above-average ragweed counts for the mid-Appalachian region.

Not medical advice. If you suspect OAS, speak with an allergist — it can sometimes progress, and symptoms that extend beyond the mouth should be evaluated.
