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 Belgium allergy season guide is published yet, so the seasonal context here follows the Continental West regional pattern.
