Tree pollen declined by 11% day over day, with the decrease primarily attributed to a drop in Oak pollen. While there’s some noise in the data, such as Cottonwood showing a 500% increase from 2 to 12, Oak’s decline is the main factor driving the overall decrease in tree pollen levels.

There are no updates on the weed side. However, on the mold side, we observed a 34% decline in mold levels. The majority of this decrease was driven by a 40% drop in ascomycetes. Additionally, grass pollen has returned to heavy levels, showing variability in its counts.
