This year's hay fever season is running significantly later than usual. Data from trusted sources like Leiden University Medical Center and Elkerliek Hospital in Helmond indicate it won't ramp up until June.

Typically, hay fever sufferers notice symptoms from early May, but based on these observations, complaints are now expected to emerge in June.
