How Metropolis’s pollen count works
Pollen rises in three overlapping waves through the year: trees release first, in late winter and spring; grasses peak from late spring into summer; and weeds — ragweed above all — take over from late summer into fall. The calendar above shows the typical peak window for each in Metropolis’s climate region, so you can see what’s likely driving your symptoms before you ever check a number.
Counts are reported on a categorical scale — None, Low, Moderate, High, and Very High. Levels run highest on warm, dry, windy mornings and fall after rain, which washes pollen out of the air. If a live count is available it appears at the top of this page; otherwise the seasonal calendar is your guide to when each allergen is in season in Metropolis.
Frequently asked
- When is pollen worst in Metropolis?
- Metropolis's pollen season runs in three overlapping waves: tree pollen peaks Feb–Apr, grass pollen Apr–Sep, and weed (ragweed) pollen Aug–Nov. The single worst stretch for most people is the spring tree peak and the late-summer ragweed peak; the live count at the top of this page tells you which is active today.
- What's pollinating in Metropolis right now?
- In June, grass pollen is in season in Metropolis — the dominant allergen you're likely reacting to right now. The live index above (when available) confirms the day's actual count; this calendar reflects the typical peak windows for Metropolis's climate region.
- Is tree or grass pollen higher in Metropolis in spring?
- In spring, tree pollen usually dominates in Metropolis — trees pollinate Feb–Apr, ahead of the grass peak (Apr–Sep). Late spring is the handoff: tree counts taper as grass climbs, so a bad April is more likely tree pollen and a bad late-May/June is more likely grass.
- How do I reduce pollen exposure in Metropolis?
- Keep windows closed and run air conditioning on recirculate during peak season; counts are highest on dry, warm, windy mornings, so time outdoor activity for late afternoon or after rain, which washes pollen out of the air. A HEPA air purifier indoors, a saline nasal rinse after being outside, showering and changing clothes before bed, and starting antihistamines before your worst season begins 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 will 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.
