Species driving Courtenay’s tree pollen

What this tree pollen level means

Low risk. Keep windows open; consider allergy meds only if sensitive.

Enjoy outdoor activities.

River-corridor elm, cottonwood and ash open from March in South Dakota, while North Dakota’s trees flower in late spring, in May. This month sits outside the usual tree pollen window for the Northern Plains pattern, so today’s tree pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. The North Dakota allergy season guide singles out ragweed, heaviest in the Red River Valley, over river cottonwood and town elm in late spring.
