Is it allergy season in Virginia?

Virginia spans the full range from Atlantic coastal plain to Appalachian mountain peaks — and that gradient means pollen season starts earlier on the coast and progressively later at elevation. Richmond sits in the fall line between piedmont and coastal plain, making it one of the earliest and most exposed cities. The DC corridor (Arlington/Fairfax) gets early tree pollen from March, while Roanoke and the Valley don't peak until April–May. Ragweed closes out the year hard through September.

Virginia's four major allergy regions — the DC Corridor, Richmond and the Piedmont, the Tidewater coast, and the Shenandoah Valley — each have distinct pollen profiles shaped by latitude, elevation, and proximity to both Atlantic moisture and Appalachian forests.

DC Corridor

Arlington and NoVA — one of the country's hardest spring seasons

Northern Virginia sits in one of the most tree-pollen-dense corridors in the US. The DC metro's urban heat island drives an early spring, with oak and maple releasing in mid-March. The combination of dense oak canopy, Potomac River valley topography, and suburban tree diversity creates overlapping pollen waves from March through May.

Richmond & Piedmont

Consistently ranked one of the worst US allergy cities

Richmond sits at the fall line where the piedmont meets the coastal plain — a natural pollen concentration zone. Tree season begins in March and peaks in April–May with oak, hickory, and birch all active at once. The James River valley can trap pollen on low-wind evenings. Ragweed season is long and severe, typically running from mid-August through early October.

Tidewater Coast

Virginia Beach and Norfolk — salt air moderates but doesn't solve

The Atlantic coast provides some sea-breeze relief — onshore winds push inland pollen back and dilute concentrations near the oceanfront. But Virginia Beach and Norfolk are still significant allergy cities. Pine pollen is especially visible in this region in April–May. The coastal plain supports high grass pollen June–July.

Shenandoah Valley

Elevation staggering — Roanoke and Charlottesville run 2 weeks behind

The Shenandoah Valley lies between the Blue Ridge and the Allegheny Mountains. Roanoke and Charlottesville see spring arrive 1–2 weeks after Richmond. The longer, cooler spring can feel milder, but the compressed bloom window means pollen levels are intense when it does peak. The Valley's mixed hardwood forests contribute high birch and oak counts in late April–May.

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.

Oak & Birch pollen

Stone fruits & apples

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

Peak risk March–May in VA. Oak is especially dominant in northern Virginia and the DC corridor, with one of the densest oak canopies in the eastern US. Peeling fruit helps — most of the cross-reactive protein is in the skin.

Grass pollen

Tomatoes, potatoes & melons

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

Peak risk June–July. Virginia's Piedmont and Shenandoah Valley fescue lawns and pastures contribute moderate grass pollen — lower than Midwest states but still significant.

Ragweed

Melons & bananas

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

Peak risk August–September. Richmond is one of the top ragweed cities in the Mid-Atlantic. Ragweed thrives along roadsides and disturbed land throughout Virginia's piedmont and coastal plain.

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.
