Southeastern Wisconsin Pollen and Mold Counts

Pollen and mold counts have not begun this year.

Check back later in the spring for new counts. Pollen counting typically starts in late March or early April, once the snow has melted and we can safely put the pollen sampler back on the roof!

Pollen and mold samples are collected at our Greenfield, WI location.

The pollen and mold counts are performed daily by the Allergy, Asthma & Sinus Center when in season, which is typically March through October. We are the only location in Southeastern Wisconsin that perfoms daily pollen and mold counts. Since pollen and mold counts are extremely weather dependent, our counts are much more accurate than those found on or, which are just based on historical data, and not on actual counts.

In addition to viewing today’s counts, you can also compare this year to past years or view the graph of annual averages. The counts are also posted on Facebook and Twitter for your convenience.
