Whatcom County Washington

                 Pollen and Mold Counts

 

Pollen and mold counts are obtained from the Asthma & Allergy Center's pollen counting station utilizing a Rotorod Aeroallergen Sampler. Counts are updated three to five times a week and provide a general representation of pollen and mold counts throughout Whatcom County. 

Readings reflect pollen and mold counts for the twenty-four hour period prior to seven a.m. of the day counts are updated. The number of pollen grains and mold spores per cubic meter is determined and reported according to the National Allergy Bureau's count designations.

Updated:  May 8, 2008      Note: Grass pollen was detected for the first time this year on 5.6.08.

Grass  37, high.    Total tree pollen: 88, moderate.   Alder, Birch 7 each, low.   Cedar 44, moderate.    Cottonwood 15, low - moderate.  Pine 15, low - moderate. Mold 58, low.

  

In general, the most important pollens this time of year are the birch and cross reactive alder pollen.  However, counts of these pollens are declining now and grass pollen will take over as the most important outdoor pollen. Grass pollen peaks at about the time the cotton fluffs peak in June.

(Mold spore count designations are different than those for pollens. See count designations above.)
