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 Phoenix’s overall trend across the week. Today’s tree pollen reading is the headline above.

Species driving Phoenix’s tree pollen

Species-level counts are not part of the modelled data Pollen Atlas publishes — the modelled index is reported per pollen type, not per species — so this section gives the type summary: tree pollen reads 17 (Low) today. 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.

Alder and hazelnut can start in January west of the Cascades, with maple and oak following through April and May. This month sits outside the usual tree pollen window for the Pacific Northwest pattern, so today’s tree pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. The Oregon allergy season guide singles out alder and hazelnut early, then the Willamette Valley’s seed grasses.

Phoenix allergies today

Phoenix allergies today are set by the same reading as the Phoenix pollen count today: the Total Pollen Index is 13 (Low), and the tree pollen index on this page is 17 (Low) of it.

Allergies in Phoenix follow the Oregon calendar set out on the full Phoenix page — the chapters, the plants behind them, and the 5-day forecast show whether today is typical for the season or an exception to it. If you are checking allergies today in Phoenix before heading outdoors, the tree pollen split on this page is the part to read: it shows whether this pollen type is doing the work today, not just how high the total sits.
