Ragweed & weeds season is underway in this region. On dry, breezy afternoons counts run highest; rain knocks pollen down for a day or two.

Poor air quality amplifies allergy symptoms — on orange days, limit long outdoor efforts.

Managing symptoms
Pollen counts peak on dry, windy afternoons and drop after rain. Keep windows closed on high days, shower after long outdoor stretches, and start antihistamines before your season begins rather than after symptoms hit. Track the daily AQI above — smoke and ozone stack on top of pollen.
