Forecast

Cold weather continues to prevent pollen count!

Due to the low temperatures and icing events of the past week, almost no pollen was registered in the ambient air. As it will remain cold in the coming days, this trend is expected to continue. Allergy sufferers should therefore only expect localised exposure in locations with highly favourable temperatures.

The purple alder can cause problems in these places. However, even this plant, which is known to start flowering around Christmas, will only be able to release a small amount of pollen due to the expected conditions, although a number of catkins still have flowering potential.

In the alder species that are more widespread in this country(black alder and grey alder), the catkins are still firmly closed and therefore cannot yet release any pollen. This also applies to the tree and shrub hazels.

The cold spell also has an impact on the flowering readiness model. From a current perspective, the data tends to indicate that flowering readiness will be reached in mid-February.
