Birch pollen increases in Central Europe: 10 day forecast


Pollen season has started in Western France and the front is about to move northwards

Over the last few days, birch pollen levels have increased across Central Europe. We are now at a stage where significant levels are recorded in Western France and on the Balkans/Austria, see the figure below. Levels are, however, still behind what they would normally be at this time of the year.

Over the next ten days, temperature is expected to be lower than normal in most of Europe, see the map below. There are exceptions: Denmark, Southern Sweden, the Baltic states, much of Poland and Belarus will be warmer than normal.

Central Europe and Southern Scandinavia can expect birch pollen next ten days

Looking ahead ten days, pollen levels are expected to stay below normal in most of Europe. This is due to temperatures lower than normal. However, we foresee birch pollen levels to increase to a moderate (yellow) level in several places across Europe (middle of France, the Balkans, Eastern Poland).

Moreover, the front is expected to move north and eastwards, covering Denmark and Southern Sweden. Even the northernmost part of Norway might see the start of season due to extraordinary high temperatures.

WHO tightens air quality guidelines

WHO releases stricter air quality guidelines to protect human health. The new standard for fine particles (PM2.5) is halved, stressing that exposure to PM2.5 is a major health risk.

The accidental badger detector

PM2.5 levels peaked late at night and early mornings at our sensor test site and we struggled to find out why. Turns out the answer had fur and four legs.

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?

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.

Green in India means red in Norway

We've attempted to compare the different PM2.5 breakpoints in selected air quality indices. It turns out a green level does not mean the same around the world.
