Is tree or grass pollen higher in Hollis in spring?

In spring, tree pollen usually dominates in Hollis — trees pollinate Apr–Jun, ahead of the grass peak (Jun–Jul). Late spring is the handoff: tree counts taper as grass climbs, so a bad April is more likely tree pollen and a bad late-May/June is more likely grass.

How do I reduce pollen exposure in Hollis?

Keep windows closed and run air conditioning on recirculate during peak season; counts are highest on dry, warm, windy mornings, so time outdoor activity for late afternoon or after rain, which washes pollen out of the air. A HEPA air purifier indoors, a saline nasal rinse after being outside, showering and changing clothes before bed, and starting antihistamines before your worst season begins 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 will 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.
