What makes Telluride's pollen season distinctive?

Telluride 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 Telluride?

Through Telluride'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.
