What's in the air in Shedd right now?

In June, grass pollen is in season in Shedd — the dominant allergen you're likely reacting to right now. A live count, when available, confirms the day's actual reading; this reflects the typical peak windows for Shedd's mild, wet Pacific Northwest climate.

Is tree or grass pollen higher in Shedd in spring?

In spring, tree pollen leads in Shedd — trees pollinate Feb–May, ahead of grass (Apr–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 Shedd's pollen season distinctive?

Shedd sits in the mild, wet Pacific Northwest zone, which means a mild, wet pattern in which a long grass season is usually the bigger problem than the early tree burst, and ragweed stays light. That shapes when symptoms hit and which allergen to watch.

How do I reduce pollen exposure in Shedd?

Through Shedd's peak windows (tree Feb–May, grass Apr–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.
