Species driving Port Gibson’s grass pollen
The modelled data reports grass as one combined index — there is no species-by-species split for grass anywhere in the data, so this page does not invent one. Today’s modelled grass index for Port Gibson is 4 (Low), and the 5-day overall trend above shows the shape of the week.
As regional context only — not as today’s readings — in the Southeast pattern, the plants that typically shape this city’s year are spring trees, warm-season grasses and late-summer ragweed.
The Mississippi allergy season guide singles out oak, pine and hickory in spring — the famous yellow pine dust is highly visible but only part of the spring story.
