Aarau Tree Pollen Count: 5-Day Forecast

Species driving Aarau’s tree pollen

What this tree pollen level means

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

Enjoy outdoor activities.

Hazel and alder open from February, and birch leads the spring peak through April and into May. This month sits outside the usual tree pollen window for the Continental West pattern, so today’s tree pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. No Switzerland allergy season guide is published yet, so the seasonal context here follows the Continental West regional pattern.
