Species driving Opal’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 0.6 (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.

Spring is a river-corridor season — cottonwood and juniper from March into May — because most of Wyoming’s trees grow where the water is. This month sits outside the usual tree pollen window for the High Basins pattern, so today’s tree pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. The Wyoming allergy season guide singles out sagebrush, the state’s signature allergen, flowering from August into October and peaking in September.

Allergies in Opal follow the Wyoming calendar set out on the full Opal 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 Opal 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.
