What this tree pollen level means

Moderate risk. If you have allergies, consider meds and limit exposure during peak hours.

Keep windows closed at midday; shower after being outside.

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