How Lyon’s pollen count works
The calendar above is tuned to Lyon’s warm, humid subtropical Southeast climate, not a national average: tree pollen peaks Feb–Apr, grass Apr–Sep, and ragweed Aug–Nov here. Those windows are why grass pollen is the one in season in Lyon right now.
Right now grass pollen leads in Lyon at a Low (2/5) level. The species actually in the air today: 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 Lyon?
- The late-summer ragweed run is the headline in Lyon: weed pollen peaks Aug–Nov, the longest and most punishing window of the year here. Tree pollen comes first (Feb–Apr) and grass bridges the gap (Apr–Sep), but it's the ragweed stretch that floors most sufferers. Currently, grass pollen is what's driving counts this month.
- What's in the air in Lyon right now?
- Right now grass pollen leads in Lyon at a Low (2/5) level. The species actually in the air today: Grasses. On a quiet live day, Lyon's seasonal calendar fills in what's typically airborne this time of year.
- Is tree or grass pollen higher in Lyon in spring?
- In spring, tree pollen leads in Lyon — 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 Lyon's pollen season distinctive?
- Lyon 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 Lyon?
- Through Lyon'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.
