August has been mostly dry, resulting in ample opportunity for weed pollen to release and travel in the wind. As a result, we are seeing high levels of Chenopods (which includes Kochia, Russian Thistle, Lambs Quarter and Careless Weed).
Juniper has overtaken Elm pollen as the major pollen in the air currently.
Elm pollen (left) starting to release in moderate amounts as of March 1st. Juniper is also at low levels. Pollen has been later than usual this year with the cooler and wetter weather. .
