What's in the air in Coesse right now?

Right now grass pollen leads in Coesse at a Low (2/5) level. The species actually in the air today: Pine, Oak, and Grasses. On a quiet live day, Coesse's seasonal calendar fills in what's typically airborne this time of year.

Is tree or grass pollen higher in Coesse in spring?

In spring, tree pollen leads in Coesse — 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 Coesse's pollen season distinctive?

Coesse 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 Coesse?

Through Coesse'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.
