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

Trees can start as early as February and peak in April. This month sits outside the usual tree pollen window for the Southeast pattern, so today’s tree pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. No PR allergy season guide is published yet, so the seasonal context here follows the Southeast regional pattern.
