When is pollen worst in Castalian Springs?

The late-summer ragweed run is the headline in Castalian Springs: weed pollen peaks Aug–Nov, the longest and most punishing window of the year here.

Is tree or grass pollen higher in Castalian Springs in spring?

In spring, tree pollen leads in Castalian Springs — trees pollinate Feb–Apr, ahead of grass (Apr–Sep). 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 Castalian Springs's pollen season distinctive?

Castalian Springs sits in the warm, humid subtropical Southeast zone, which means an unusually long, overlapping season — the warm climate stretches grass across much of the year and pushes ragweed deep into autumn. That shapes when symptoms hit and which allergen to watch.

How do I reduce pollen exposure in Castalian Springs?

Through Castalian Springs's peak windows (tree Feb–Apr, grass Apr–Sep, ragweed Aug–Nov), 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.
