Due to the mild months of February and March, birch trees bloom a little earlier than usual. As a result, people with a birch pollen allergy may already experience problems, while this usually only happens at the beginning of April. The peak of the birch pollen season is expected in early April. Meteovista let us know.
The first half of this week will be very mild with highs rising widely to 14 to 18 degrees and there will be sunny periods. This will cause more and more birches to blossom. There will be no significant rain until Thursday and the amount of pollen in the air will increase.
“Those who are very sensitive to birch pollen can already develop complaints at low amounts of birch pollen,” says Jaco Van Wezel of Meteovista. “Birch pollen is highly allergenic and causes complaints in approximately half a million Belgians during the peak period. The peak of the birch pollen season will probably occur in early April this year.”
The birch is the tree that causes the most hay fever complaints. Then come the hazels, alders and ash trees, which spread moderately allergenic pollen. The hazels have almost all finished flowering, except for a few curly hazels. Many alders have also already finished blooming, but some trees still spread pollen. The ash tree is currently in bloom.
Due to the mild weather, the grass is already starting to grow considerably and flowering will also start earlier than average. This means that by mid-April, early flowering grass species, such as the foxtail, may already be spreading pollen. Grass pollen is highly allergenic and causes hay fever symptoms in a million Belgians.
