Seasonal Tips

  • January-March: Hazel and alder start early. Watch for mild winter spells triggering early pollen release.
  • April-May: Birch and ash peak. This is the most challenging period for tree pollen allergy sufferers.
  • June-July: Grass pollen dominates. Consider indoor activities during midday when counts peak.
  • August-September: Mugwort and ragweed season. Ragweed is increasingly common in eastern regions.
