Species driving Herculaneum’s tree pollen

The plant-by-plant detail that is available, from the Google Pollen API, is in the next section.

What this tree pollen level means

Low risk. Keep windows open; consider allergy meds only if sensitive.

Enjoy outdoor activities.

River-corridor trees open from February — elm and maple first, then oak and hickory. This month sits outside the usual tree pollen window for the South-Central Plains pattern, so today’s tree pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. The Missouri allergy season guide singles out oak and hickory over an elm and maple opening, in a season written by the state’s rivers.
