How Rock Hall’s pollen count works

The calendar above is tuned to Rock Hall’s cold-temperate Northeast climate, not a national average: tree pollen peaks Mar–May, grass May–Jul, and ragweed Aug–Oct here. Those windows are why grass pollen is the one in season in Rock Hall right now.

Right now grass pollen leads in Rock Hall at a Low (2/5) level. The species actually in the air today: Pine, Oak, and Grasses. Counts run highest on warm, dry, windy mornings and drop after rain, which washes pollen out of the air — reported on the None / Low / Moderate / High / Very High scale.

Frequently asked

When is pollen worst in Rock Hall?
Rock Hall runs the classic three-wave calendar: tree pollen Mar–May, grass May–Jul, then ragweed Aug–Oct. The two worst stretches are the spring tree peak and the late-summer ragweed peak. Currently, grass pollen is what's driving counts this month.
What's in the air in Rock Hall right now?
Right now grass pollen leads in Rock Hall at a Low (2/5) level. The species actually in the air today: Pine, Oak, and Grasses. On a quiet live day, Rock Hall's seasonal calendar fills in what's typically airborne this time of year.
Is tree or grass pollen higher in Rock Hall in spring?
In spring, tree pollen leads in Rock Hall — trees pollinate Mar–May, ahead of grass (May–Jul). The handoff is the tail of the tree window: tree counts taper as grass climbs, so an early-spring flare is more likely tree pollen and a late-spring one more likely grass.
What makes Rock Hall's pollen season distinctive?
Rock Hall sits in the cold-temperate Northeast zone, which means a sharply defined calendar — a hard winter lull, then a compact spring tree burst before grass and a long ragweed fall. That shapes when symptoms hit and which allergen to watch.
How do I reduce pollen exposure in Rock Hall?
Through Rock Hall's peak windows (tree Mar–May, grass May–Jul, ragweed Aug–Oct), keep windows shut and run AC on recirculate; counts run highest on dry, warm, windy mornings, so push outdoor activity to late afternoon or just after rain, which clears pollen from the air. A HEPA purifier indoors, a saline rinse after being outside, showering before bed, and starting antihistamines a week or two before your worst local window all measurably cut symptoms.
What pollen index counts as high?
Pollen is reported on a categorical scale — None, Low, Moderate, High, and Very High. "High" and above means most allergy sufferers notice symptoms even with brief outdoor exposure, and sensitized people should limit time outside and pre-medicate. "Low" to "Moderate" usually only affects highly sensitive individuals.
