Spring in Europe – alder, hazel and birch pollen

-

We are heading into warmer and lighter days in Europe, lockdowns or not. And no surprise, the pollen is faithfully here.

Pollen from alder and hazel on decline

There have been fairly high levels of pollen from hazel and alder in Europe over the last few weeks. However, it looks like we have passed the peak, levels for these two species are now declining in Western Europe.

Birch is coming

Birch pollen is a major cause of allergic reactions in Europe. April and May are normally the peak for birch pollen, and as expected we see the spread starting in Central Europe, Switzerland and France.

The birch pollen release will strengthen and move northwards as spring progresses. You may want to take a look at our video displaying the normal birch pollen development in Europe.

We’re measuring pollen!

We are running our airminer 2.0 sensors to calculate local pollen levels. As expected, pollen levels vary with temperature and precipitation, but we also see significant variations through the day.

When to expect birch pollen in Norway?

Hazel and alder is flowering in Southern Norway, but the key allergen to many of us is birch. When can we expect the birch pollen season to start?

Grass pollen is the most common pollen allergy in Europe and the season is well under way. Central Europe can expect high levels, while the cold weather further north let us wait for the spread.

Air pollution kills – and costs

About 7 million people die from air pollution annually, and costs to society are huge. But lots can be - and is - done to reduce it.
