7-Day Pollen Forecast for Cologne
Pollen Season in Cologne
Cologne sits in the Kölner Bucht, one of the mildest, most sheltered corners of Germany, and that warmth pulls the season forward. Hazel and alder can flower in the floodplain woods along the Rhine as early as January in a mild winter, running through February and into March. Birch is the sharpest peak: it usually builds in the first half of April and fades by early May, and the city is well supplied with birches in the Inner and Outer Grüngürtel, the Stadtwald in Lindenthal and residential streets in Nippes and Ehrenfeld. Plane trees along the Rhine promenade and Ringe add a shorter April irritant. Grasses take over from May, peaking in June and easing through late July, and they are worst on the open meadows of the Rheinpark, Volksgarten, Beethovenpark and the Poller Wiesen. Rye and other cereals on the loess farmland of the surrounding Börde contribute in June on westerly and southwesterly winds. Mugwort follows on railway embankments and waste ground in July and August; ragweed is present only sporadically.
- On June mornings, take your run along the Rhine embankment rather than across the open meadows of the Poller Wiesen or Rheinpark, where grass pollen sits thickest.
- Cologne's urban heat island keeps evenings warm and airborne counts up late, so air out your flat in the early hours rather than at dusk in peak weeks.
- If you cycle the Ringe or the Grüngürtel paths daily, wraparound glasses and a rinse of face and hair when you get in make a noticeable difference in April.
