Allergy Shots in New Hampshire: What to Know
New Hampshire's vast birch-maple-oak forests compress tree pollen into an intense late April through May burst, while the heavily forested terrain produces enormous leaf-litter mold loads through fall. Boston-area pricing spillover in southern NH pushes allergy costs above many New England.
Top Allergens in New Hampshire
The most common allergens affecting residents of New Hampshire, ranked by severity and seasonal impact.
Birch (Betula spp.) Pollen
SevereNew Hampshire's vast white, yellow, and gray birch stands across the White Mountains and central forests produce highly allergenic wind-borne pollen. Dartmouth-Health allergists flag birch as the most clinically significant tree allergen in the state.
~25–30% of NH allergic rhinitis patients sensitized to Bet v 1
Maple / Box Elder (Acer spp.) Pollen
ModerateSugar maple is New Hampshire's state tree. Red maple and box elder add early pollen, and the cool climate compresses bloom into a 3–4 week window with intense local counts.
Oak (Quercus spp.) Pollen
SevereOak is the heaviest single-species pollen producer in southern New Hampshire's Hillsborough and Rockingham Counties. Counts routinely reach 'very high' through May in Manchester and Concord.
Timothy / Kentucky Bluegrass (Phleum pratense, Poa pratensis) Pollen
ModerateNew Hampshire's hayfield and dairy-pasture landscape in the Connecticut and Merrimack River Valleys is dominated by timothy and bluegrass, two of the most allergenic grass species.
Common Ragweed (Ambrosia artemisiifolia)
ModerateLess dense than Pennsylvania or New Jersey due to cold nights, but climate-change first-frost delays of 10–14 days since 1990 have noticeably extended ragweed exposure in New Hampshire.
Cladosporium / Alternaria Mold
ModerateNew Hampshire's heavily forested terrain produces enormous leaf-litter mold loads. Lakes Region humidity elevates outdoor spore counts from summer through October.

Why Allergies Are Worse in New Hampshire
New Hampshire is over 80% forested with oak-maple-birch-beech-hemlock canopy. The White Mountains elevation gradient delays tree pollen at higher elevations by 2–3 weeks, compressing pollen into intense late-spring overlap. The March–April mud season triggers early mold before pollen even begins.
White Mountains Elevation Gradient
Higher elevations in the Whites delay tree pollen by 2–3 weeks compared to the Merrimack Valley, but compress birch, oak, maple, and elm pollen into an intense late April through May overlap once warm air arrives.
Dense Northern Hardwood Canopy
New Hampshire's near-continuous forest cover — over 80% forested — saturates the air with tree pollen statewide. Small birch pollen grains can travel hundreds of miles, blanketing even non-forested areas.
Mud Season Mold Bloom
The March–April thaw produces saturated soils, rotting leaf litter, and basement dampness across New Hampshire, triggering an early Cladosporium and Alternaria mold surge before tree pollen even begins.
