Pollen Count (Week of June 15, 2019)

Airborne sampling weekly from the roof of the Queen of the Valley Medical Center, Napa, CA. 

Total Pollen
- Trees:10
- Grasses: 62
- Weeds: 18
Total Mold: Low

What a little heat and wind can do. Yikes.  Another spike in grass pollen last weekend.   Grass pollen should be finished in about two weeks. This season is longer than usual becauase of our late rains.  Weed pollen is predominantly from chamise  or greasewood, found in the chaparral.  Lots while hiking in Skyline Park.    https://calscape.org/Adenostoma-fasciculatum-()



What’s Happening

June 2019

About a third of people with seasonal allergies have indoor allergies that make them worse in season, but aren’t enough to trigger symptoms out of season.   Make sure you create an environment in your bedroom where you minimize allergen exposure.  Waking up clear in the morning will lessen then impact of outdoor exposures.
