Pollen Atlas models the daily detail as an overall index: day-by-day splits by individual pollen type are not part of the modelled data, so this table shows Guernsey’s overall trend across the week. Today’s grass pollen reading is the headline above.

Species driving Guernsey’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 Guernsey is 0.6 (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 High Basins pattern, the plants that typically shape this city’s year are river-corridor cottonwood and juniper, brief-summer meadow grasses, and sagebrush flowering late.

The Wyoming allergy season guide singles out sagebrush, the state’s signature allergen, flowering from August into October and peaking in September.
