This page is dedicated to reporting the pollen and fungal spore levels in the East Midlands, paying particular mention to those known to be allergenic. This page will be updated regularly in the peak season (June/August) and as and when necessary outside these months.

The information provided is for the interest of, and use by, the general public only.

Recent pollen levels

All pollen

High levels of nettle and low levels of dock, elder, lime, mugwort, plantago, pine, and yew type have also been recorded. Grass has been low in the last week, allergic individuals may still need to take necessary precautions.

Grass pollen

Counts represent the average number of grass pollen grains per cubic metre of air for the period covering 9am on the date shown to 9am the following day. Counts are converted to a classification according to the table further down this page. 


Date Pollen level
30/07/2020 Low

Recent fungal spore levels

The 2020 fungal spore season is ongoing and we are monitoring airborne fungal spores regularly. Counts in the last week have been moderate. Of the two well-known allergenic fungi, Alternaria was above allergenic levels in the last 7 days. Cladosporium continues its trend of being over the allergenic threshold in the last week. Allergic individuals should take the necessary precautions.
