Likely:
| Rank | Pollen type | Why it fits your log (Basel 2025) | Typical season window (Basel lowlands) |
|---|---|---|---|
| 1 | Birch (Betula) | First strong bout began 28 Apr, right when birch was still shedding very allergenic pollen after an intense April bloom. | Mid-Mar → late-Apr, can linger into early May in mild years ([meteonews.ch][1]) |
| 2 | Oak (Quercus) | Second, even stronger flare-up 10-22 May lines up with the oak peak that follows birch and overlaps the turn of May. | Late-Apr → mid-Jun, highest around early–mid May ([meteonews.ch][1]) |
| 3 | Beech / hornbeam group | These trees flower alongside oak and share many birch-family allergens; could intensify mid-May symptoms. | Late-Apr → late-May ([meteonews.ch][1]) |
| 4 | Early grasses (Poaceae) | Basel’s grass season kicks off end-Apr but usually stays high through June; your symptoms stopped in early June, so grass is a secondary suspect, not primary. | Mid-May → Jul, peak late May–Jun ([pollencount.eu][2], [meteonews.ch][1]) |
the Allergies are now gone for a couble of weeks. Perhaps 2-3.
I have bought allergy medicine around April 28, and I did not fully use them.
Allergies started strongly (6/10).
The Allergies weakened quickly within 2 weeks until almost no problems were present
Allergies Kicked in very strongly (7/10) including sneezing, running nose, burning sensation in Nose, throat and eyes
Intensity went up further. I think I cean really feel when a specific pollen or so gets stuck in my nose with a strong itching feeling as well as strong sneezing.
Light trouble to Breathe, Tears in eyes as well as a very strong feeling of a foreign body in my throat when gulping down saliva (as if a fly is stuck in throat)
allergies have calmed down recently
The recent 5 days, I had to take medication, allergies were very strong
