Is tree or grass pollen higher in Cal-Nev-Ari in spring?

In spring, tree pollen leads in Cal-Nev-Ari — trees pollinate Jan–Apr, ahead of grass (Mar–Jun). 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 Cal-Nev-Ari's pollen season distinctive?

Cal-Nev-Ari sits in the arid Southwest desert zone, which means an early tree season and a comparatively light, short ragweed season — the dry desert air suppresses the weed load that hammers wetter regions. That shapes when symptoms hit and which allergen to watch.

How do I reduce pollen exposure in Cal-Nev-Ari?

Through Cal-Nev-Ari's peak windows (tree Jan–Apr, grass Mar–Jun, 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.
