High birch pollen levels expected across Central Europe

-

Warm weather means high level of birch pollen across Europe next ten days; the front is moving northwards to Norway and Finland

As illustrated in the figure below, the birch pollen season is well underway in Europe, with high levels recorded in France, Germany and Austria.

Warm weather and pollen ahead

The next ten days will be warm in most of Europe, typically 7-9 degrees warmer than normal, see the figure below. This map shows the difference between the ten day weather forecast and what the temperature would normally be at this time of the year. Particularly France, Switzerland, Northern Spain and Southern Germany are likely to see much higher temperatures than normal.

Tempdiff 08-17 April 2020
Temperature differences from normal levels, 08-17 April 2020. Blue and green means colder than normal, orange and red warmer.

Consequently, pollen levels are expected to increase rapidly in most of Europe. The front will continue to move northwards through Baltikum and into Finland. Southern Sweden and the south east of Norway will also see rising birch pollen levels, see the figure below.
