Typical peak months for each pollen type in this climate region. The highlighted column is the current month.
How Heron’s pollen count works
The calendar above is tuned to Heron’s high-elevation Mountain West climate, not a national average: tree pollen peaks Mar–May, grass May–Jul, and ragweed Aug–Oct here. Those windows are why grass pollen is the one in season in Heron right now.
Right now tree pollen leads in Heron at a Low (2/5) level. The species actually in the air today: Birch, Pine, Oak, and Grasses. Counts run highest on warm, dry, windy mornings and drop after rain, which washes pollen out of the air — reported on the None / Low / Moderate / High / Very High scale.
Frequently asked
- When is pollen worst in Heron?
- Heron runs the classic three-wave calendar: tree pollen Mar–May, grass May–Jul, then ragweed Aug–Oct. The two worst stretches are the spring tree peak and the late-summer ragweed peak. Currently, grass pollen is what's driving counts this month.
- What's in the air in Heron right now?
- Right now tree pollen leads in Heron at a Low (2/5) level. The species actually in the air today: Birch, Pine, Oak, and Grasses. On a quiet live day, Heron's seasonal calendar fills in what's typically airborne this time of year.
- Is tree or grass pollen higher in Heron in spring?
- In spring, tree pollen leads in Heron — trees pollinate Mar–May, ahead of grass (May–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 Heron's pollen season distinctive?
- Heron sits in the high-elevation Mountain West zone, which means short, sharp seasons set late by elevation, with sagebrush adding to the late-summer weed load. That shapes when symptoms hit and which allergen to watch.
- How do I reduce pollen exposure in Heron?
- Through Heron's peak windows (tree Mar–May, grass May–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.
