Pollen Season in Hamburg

Hamburg's maritime climate — mild, damp winters and cool summers moderated by the North Sea and the Elbe — gives it an early start and a drawn-out season. Hazel and alder often release pollen in January or February, and alder is especially abundant along the Alster canals, the Elbe marshes and Wilhelmsburg's wet woodland. Birch is the defining allergen of the north German spring: it dominates from around mid-April, peaks over a couple of intense weeks, and fades by late May. Birch is planted heavily in Hamburg's parks and gardens — Stadtpark in Winterhude, Jenischpark, Volkspark, Planten un Blomen and the vast Ohlsdorf cemetery all carry it. Ash and oak overlap in spring; plane trees add an irritant dust downtown. Grasses take over from late May through July, worst over the open meadows of the Vier- und Marschlande, the Alsterpark lawns and the Elbe dikes. Mugwort follows in July and August on wasteland and along rail corridors and the port. Prevailing westerlies off the sea usually keep counts lower than inland Germany, and a genuine onshore breeze can wash the air clear.

• On birch days in late April, keep away from Stadtpark and Ohlsdorf in the morning and take your walk along the Elbe at Övelgönne instead, where an onshore wind keeps counts down.
• Dry, warm easterly weather in spring brings the highest loads to Hamburg — check the wind direction as well as the count before planning time outdoors.
• Ventilate your flat late in the evening or after one of Hamburg's frequent rain showers, when pollen has settled, and ask a pharmacist in good time rather than waiting for the birch peak.
