Species driving Westfield’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 Westfield is 2 (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 Midwest & Great Lakes pattern, the plants that typically shape this city’s year are spring trees, late-spring and summer grasses, and late-summer and autumn ragweed.

The Indiana allergy season guide singles out ragweed above all — the state’s defining allergen — over a maple, elm and oak spring.
