Species driving Seguin’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 Seguin is 6 (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 Gulf & South Texas pattern, the plants that typically shape this city’s year are spring trees, warm-season grasses, late-summer ragweed and winter mountain cedar in the west of the region.

The Texas allergy season guide singles out mountain cedar — Ashe juniper — in winter, oak in spring and ragweed from August.
