UK pollen count calendar

Ever frantically googled, “pollen count today near me” in the hopes to see a low number so you’re not sniffling and sneezing throughout the day?

Be prepared in advance this year, with our help. From tree to bee, check our UK pollen count calendar to see how your hay fever might affect you this month… 

What is pollen?

It’s worth knowing what pollen actually is before we dive into the pollen count season by season.

Pollen is described as a mass of microspores in a seed plant, and it looks like a fine dust to the human eye.

Like we learnt in school, pollen is transported by bees, but also by wind, water and other insects too!²

Season by season pollen count

To make things easier for you, we’re going to break things down season by season, and then month by month for a little more detail.

This information is all based on research by the University of Worcester.³
